“Galactic Problem Solver”— NASA’s Recognition for Aryyama Kumar Jana’s Solar Irradiance Tracking 

On November 15th, MetaAI and Papers with Code announced the release of Galactica, a game-changer, open-source large language model trained on scientific knowledge with 120 billion parameters. As one of my friends , the model can write whitepapers, reviews, Wikipedia pages, and code. It knows how to cite and how to write equations. It’s kind of a big deal for AI and science. shared on Twitter On November 17th, Galactica was shut down. Why? Because, as with all deep learning models, it didn’t understand the task at hand and was wrong in many cases. This shouldn’t be an issue, especially if we add a warning saying the model may be wrong and not to trust it blindly. Just like nobody trusted Wikipedia, we couldn’t put this as a reference in High School projects. The issue is that . Galactica was wrong or biased but sounded right and authoritative Still, the model is available to researchers, and I believe it is important to keep it open-sourced. As another one of my friend's shared, all the drama around the new model seems a bit excessive. Of course, the model isn’t perfect, just like all others that are currently available online. We need it online to test its limitations, work on it and improve it. We should see these kinds of publications as students and allow for mistakes and improvements without fear of being shut down or canceled. Anyways, we are not here to discuss that. Hopefully, . it will be back online soon We are here to see what Galactica is, or was, and how it could achieve writing papers, reviews, code, and more… Learn more in the video References ►Read the

here to discuss that hopefully it will 1:28 be back online soon we are here to see 1:30 what Galactica is or was and how it 1:33 could achieve writing papers reviews 1:35 code math and more basically Galactica 1:39 is a large language model with a size 1:41 comparable to gpt3 but specialized on 1:44 scientific knowledge more precisely it 1:46 was trained on a large and curated 1:48 Corpus of scientific knowledge including 1:50 over 48 million papers textbooks and 1:54 lecture notes millions of compounds and 1:56 proteins scientific websites 1:58 encyclopedias and more as they highlight 2:00 data were of high quality and highly 2:03 curated which is one of the big 2:05 difference with gpt3 So in theory 2:08 Galactica contains pretty much all of 2:10 Humanity's scientific knowledge imagine 2:12 having an amazing memory and the time to 2:15 read millions of research remembering 2:18 most of it well this is Galactica it 2:21 seems like its memory isn't so good 2:23 after all and it mixes everything even 2:25 though we could assume most information 2:27 present in the training data set was 2:29 accurate even considering all devices 2:31 and failures Galactica stays pretty 2:34 powerful and outperforms pretty much all 2:36 other approaches for scientific related 2:39 tasks it's just not enough for a product 2:41 we can have confidence in still it's 2:44 worth understanding how it works 2:46 especially because it will come back 2:48 even more powerful pretty soon as we 2:51 mentioned Galactica is a large language 2:53 model similar to gpt3 or Bloom 2:55 specifically trained for as they say 2:58 organize science there's also a lot of 3:01 engineering going on in this model 3:03 allowing so much versatility in its 3:05 inputs and outputs like special 3:07 tokenization of citations or protein 3:09 sequences which you can learn more in 3:11 their paper linked below their 3:13 tokenization effort is by far the 3:15 biggest contribution of this work 3:17 tokensation basically means the way the 3:20 model will see the data instead of words 3:23 math or shapes that we understand I 3:26 actually share a video on embedding and 3:28 tokenization later this week so if that 3:30 sounds interesting stay tuned for that 3:33 and subscribe to not miss it so accept 3:35 this weird tokensation and 3:37 pre-processing steps what is Galactica 3:39 and what does it do after taking the 3:42 words or different scientific inputs and 3:44 preparing it for the model doing 3:46 tokenization no surprise Galactica is 3:50 yet another Transformer based 3:52 architecture like gpt3 with a couple of 3:55 variations including the tokenization 3:57 differences so I definitely invite you 3:59 to but one of the many videos I or some 4:02 of my friends made covering the 4:04 Transformer architectures as I won't get 4:06 into how they work once again the second 4:09 major difference between Galactica and 4:11 other large language models is what they 4:13 call the prompt pre-training this means 4:16 that they will include prompts extracted 4:18 from the training data set alongside the 4:21 data itself which has been shown to 4:23 maximize the generality of the model 4:25 while boosting performance on some tasks 4:28 of interest and that's pretty much it as 4:31 I said the architecture is very similar 4:33 to what you already know and mostly the 4:35 training and pre-processing schemes vary 4:37 which shows that the model isn't 4:39 everything but how we preach through the 4:41 data for it might actually matter even 4:43 more you can basically see the 4:45 difference between gpt3 and Galactica as 4:48 the same student with a bad science 4:49 teacher versus a good one it has the 4:52 same capabilities and resources the 4:55 teacher just made it more accessible and 4:57 understandable for him of course this 4:59 was just an overview of the paper and I 5:02 strongly recommend reading it there are 5:04 tons of details about the multiple 5:06 engineering tricks they've implemented 5:08 along with results analysis details on 5:11 all the tasks they tackle using the 5:13 model and how it understood the input 5:15 data and its predictions its limitations 5:18 biases and more I hope you've enjoyed 5:21 this video and I will see you next week 5:23 with another amazing paper and a special video covering what embeddings are

INTRODUCTION Most nearby galaxies are found to harbor central supermassive black holes (SMBHs) whose masses are correlated with properties of the stellar components of their hosts (e.g., Magorrian et al. 1998; Ferrarese & Merritt 2000; Gebhardt et al. 2000; Kormendy & Ho 2013). However, the details of how gas flows into the galactic nucleus from large cosmic distances and how the SMBH in turn imparts feedback into the galaxy remain coupled unresolved problems. Recently, some attempts to connect these disparate scales have been made using nested simulations where each smaller-scale simulation is initialized from the next larger-scale simulation (e.g., Hopkins & Quataert 2010; Ressler et al. 2020; Guo et al. 2023); or by adopting Lagrangian hyper-refinement methods (e.g., Angl´esAlc´azar et al. 2021; Hopkins et al. 2023); or by pushing out the simulation regime to larger scales (e.g., Lalakos et al. 2022; Kaaz et al. 2023). While successful in studying the process of accretion, feedback from the SMBH has not been followed out to galaxy scales in prior work because either the communication between scales is only directed inwards or because of the inability to include the entire galaxy and the black hole. We employ here a multi-zone computational method which represents a first attempt to not only follow accretion flows but also trace feedback across 7 orders of magnitude from the event horizon to galactic scales. With this method, we study purely hydrodynamic Bondi accretion as well as the magnetized Bondi problem. The outline of this Letter is as follows: In Section 2 we give an overview of the numerical scheme that captures a wide dynamic range simultaneously. In Section 3, we present a purely hydrodynamic simulation and test our numerical scheme by comparing against the general relativistic (GR) analytical solution. In Section 4 we include magnetic fields for a more realistic representation of the environment of SMBHs and study how Bondi accretion is modified. We discuss our findings of feedback via convection in Section 5 and summarize conclusions of our study in Section 6. Additional details are presented in a set of short appendices: various GRMHD quantities are defined in Appendix A, the details of the simulation set-up are outlined in Appendix B, and a resolution and initial condition study is presented in Appendix C.

INTRODUCTION Most nearby galaxies are found to harbor central supermassive black holes (SMBHs) whose masses are correlated with properties of the stellar components of their hosts (e.g., Magorrian et al. 1998; Ferrarese & Merritt 2000; Gebhardt et al. 2000; Kormendy & Ho 2013). However, the details of how gas flows into the galactic nucleus from large cosmic distances and how the SMBH in turn imparts feedback into the galaxy remain coupled unresolved problems. Recently, some attempts to connect these disparate scales have been made using nested simulations where each smaller-scale simulation is initialized from the next larger-scale simulation (e.g., Hopkins & Quataert 2010; Ressler et al. 2020; Guo et al. 2023); or by adopting Lagrangian hyper-refinement methods (e.g., Angl´esAlc´azar et al. 2021; Hopkins et al. 2023); or by pushing out the simulation regime to larger scales (e.g., Lalakos et al. 2022; Kaaz et al. 2023). While successful in studying the process of accretion, feedback from the SMBH has not been followed out to galaxy scales in prior work because either the communication between scales is only directed inwards or because of the inability to include the entire galaxy and the black hole. We employ here a multi-zone computational method which represents a first attempt to not only follow accretion flows but also trace feedback across 7 orders of magnitude from the event horizon to galactic scales. With this method, we study purely hydrodynamic Bondi accretion as well as the magnetized Bondi problem. The outline of this Letter is as follows: In Section 2 we give an overview of the numerical scheme that captures a wide dynamic range simultaneously. In Section 3, we present a purely hydrodynamic simulation and test our numerical scheme by comparing against the general relativistic (GR) analytical solution. In Section 4 we include magnetic fields for a more realistic representation of the environment of SMBHs and study how Bondi accretion is modified. We discuss our findings of feedback via convection in Section 5 and summarize conclusions of our study in Section 6. Additional details are presented in a set of short appendices: various GRMHD quantities are defined in Appendix A, the details of the simulation set-up are outlined in Appendix B, and a resolution and initial condition study is presented in Appendix C.

May 2024's Must-Play List: The Top 10 Game Releases You Can't Miss

"To be governed is to be watched, inspected, spied upon, directed, law-driven, numbered, regulated, enrolled, indoctrinated, preached at, controlled, checked, estimated, valued, censured, commanded, by creatures who have neither the right nor the wisdom nor the virtue to do so. To be governed is to be at every operation, at every transaction noted, registered, counted, taxed, stamped, measured, numbered, assessed, licensed, authorized, admonished, prevented, forbidden, reformed, corrected, punished. It is, under pretext of public utility, and in the name of the general interest, to be placed under contribution, drilled, fleeced, exploited, monopolized, extorted from, squeezed, hoaxed, robbed; then, at the slightest resistance, the first word of complaint, to be repressed, fined, vilified, harassed, hunted down, abused, clubbed, disarmed, bound, choked, imprisoned, judged, condemned, shot, deported, sacrificed, sold, betrayed; and to crown all, mocked, ridiculed, derided, outraged, dishonored. That is government; that is its justice; that is its morality." - Pierre-Joseph Proudhon, The General Idea of the Revolution In vivid words, Proudhon describes the core of state authority as brutal subjugation: Surveillance, control, regulation, restriction, exploitation, and even blunt violence. Contemplating Guantanamo Bay, national debt, Snowden, inflation, and Julian Assange, even the most staunch believers of our liberal democracies have to either catch the scent of truth in it or engage in vertiginous feats of mental acrobatics. The liberation? Autonomy. The purest and most radical following and implementation of this principle in the history of mankind is arguably the . From the mining of the first 50 , to the EVM, to Parachains and Danksharding, every step in this space of maximum decentralization is underlined by the moral imperative that increasing the autonomy of individuals is desirable. Web3 space BTC However, as important as it is to achieve autonomy from all claims to power, the question remains about what we should do with this Autonomy. In our desire to create a better world, is autonomy the value we should try to maximize? If the only aim of spelling out freedom is to create as much space as possible for undisturbed self-expression, then this freedom is threatened to remain empty, dead, and meaningless. Although, as the absence of obstacles and undesired influences, a purely negative conception of freedom is not enough to give our lives meaning and orientation. Therefore, autonomy must not be misunderstood as an end in itself. Instead, we must understand it as the foundation and enabling condition for resonant world relations. I would like to argue that the pure value of autonomy requires a supplement to unfold its utopian potential: social freedom. Autonomy Uncontested The value of autonomy enjoys an almost unchallenged status in our society. In all political spectrums ("My body, my choice" / "Taxes are theft" / "Better dead than red"), in culture (glorification of world traveling influencers, the explosion of interest into self-improvement, the rise of non-traditional relationships, etc. ), art (tropes about oppression/emancipation), everywhere the unquestioned virtue of autonomy shines through. This development has reached its climax in the decentralized space. Here, autonomy is not just one value among many but the central ethical guiding principle from which everything else is derived. The vision of a world where individuals can interact directly with each other without intermediaries or higher authorities is the utopian core of the web3 landscape. Indeed, the decentralized space has an emancipatory potential that can not be underestimated. Many of our institutions are, in the best case, unsuitable for the problems of the 21st century and, in the worst case, rotten to the core. By creating structures that enable individuals to govern their data, finances, identities, and contracts themselves, decentralized technologies have the potential to shift power away from gatekeepers to society. But what is autonomy? Autonomy, negative and social freedom The term autonomy is derived from the ancient Greek "autonomía," which means something like "self-legislation" or "self-determination." Autonomy is often understood as the ability to emancipate oneself from external influences and constraints. Proudhons quote and my examples reference that understanding of autonomy. This notion of autonomy thus shows a great affinity to the concept of negative liberty, as prominently defined by Isaiah Berlin and is famously represented by Thomas Hobbes's quote "A free man is he that in those things which by his strength and wit he is able to do is not hindered to do what he hath the will to do" Negative liberty denotes a state of absence of external obstacles and limitations. It realizes itself in a protected space of individual decision and action freedom to be exposed to as few interventions as possible. It is precisely this ideal that many advocates of decentralized systems also invoke: The substitution of hierarchical structures by autonomous actors is supposed to enable more negative freedom by removing boundaries and obstacles. The gold standard of a decentralized system is its robustness to censorship and, therefore its ability to maintain boundaries and degree of freedom against external forces. However, is the protection and expansion of negative freedom sufficient to enable people to lead a truly self-determined and fulfilled life? The philosopher Axel Honneth has convincingly argued that this is not the case. For him, individual freedom only becomes possible where it can relate to an "objective reality", i.e. to given social conditions and institutions. True self-determination, therefore, always presupposes a social context in which the individual can realize his or her life plans. Honneth calls the form of freedom that arises from this "social freedom", which he derived from Hegel. According to Honneth, it is not enough for a free individual to be devoid of obstacles. Instead, it necessitates a state in which individuals support each other in realizing their respective goals, enabling each other to lead a self-determined life. That is all quite abstract, so Let's visualize the difference between the two concepts of freedom in the following picture: Imagine you are in front of a river that you want to cross. The river looks quite dangerous; you could be swept across or drown in a whirlpool. Hobbes is sitting next to you on a stone and tells you that you have every freedom to cross this river. After all, there are no dangerous animals in the water. (There are also no border guards with machine guns, and no wall has been erected). However, you are completely on your own. It's just your subjective experience, and you can't hope to make it, should you try. However, it could also be that a tree has accidentally fallen, and you can get across quite easily. For Hobbes, though, it makes no difference to your freedom whether you live in a world in which this tree has fallen or not. At that moment, Hegel arrives with a good wine in his hand and a wheelbarrow full of planks and nails. He offers to build a bridge together because he wants to cross it himself. For Hegel, only now have you gained your freedom, because in reality, the conditions have been created through which you can hope to actually cross the river. Before, it was pure chance whether this hope could be rationally justified. It was only through Hegel that you actively received the support from your environment that can give you rational hope of reaching your goal (the other shore). This applies to societies. It is, as supporters of Hegel's idea would argue in societies without social freedom pure chance whether you grow up in circumstances that enable you to achieve your goals and in which everyone can hope to achieve their goals. In societies with social freedom, however, this hope is justified because the objectives of the other subjects are such that they enable and complement the achievement of one's own goals and complement them. Social freedom thus has a cooperative core: it is based on the insight that the freedom of the individual is dependent on the freedom of others. Only in a community in which people grant and support each other in the development of self-determination can the individual also experience himself as genuinely free. The values of the decentralized space have to be ultimately also committed to such an understanding of social freedom, even if this is not always explicitly reflected. Behind the efforts to create decentralized, self-organized structures has to be the vision of a world in which individuals can freely associate to collectively shape their living conditions with each other for the better. Even the much-cited "trustless trust" and allegedly increase of freedom that blockchain technologies are supposed to enable is ultimately grounded in the individual’s faculty to understand the system. It makes a huge difference if 99,9999& of crypto projects are scams, or if it’s only 80, 70, or 60. However, the fixation on code-based incentive and coordination mechanisms threatens to lose sight of this fact. You could easily imagine a future in which every aspect of societal organization is managed by smart contracts, but in which more people are scammed; more people lack connections and meaning and fewer people can make sense of this world. Conclusion The vision of autonomy that inspires so many in the blockchain space is a noble and important one. Establishing robust individual freedoms and consent is crucial to human flourishing. But to unlock the full transformative potential of decentralized technologies, we must pair the pursuit of autonomy with the cultivation of social freedom. This means aspiring not just for freedom from interference but also to enable the creation of resonance - meaningful, mutually empowering relationships - at both the individual and the institutional level. It means recognizing that our identities are not atomic, but fundamentally intersubjective - our agency is enhanced, not undermined, by positive embeddedness in the social fabric. And it means harnessing the power of decentralized coordination not just to maximize individual gain, but to create emergent realities that are greater than the sum of their parts. By synthesizing the principles of individual sovereignty and collective intelligence, the marriage of autonomy and resonance paves the way for a future that brings out the best in both individuals and the whole. A future where people are free to author their own lives, while also synergizing with others to make the pie massively bigger for everyone. Getting there won't be easy, requiring technical and cultural innovation. But if we can pull it off, the prize is immense - nothing short of the difference between a failed species and a thriving galactic civilization. So let us not settle for autonomy alone but strive for resonant autonomy—the foundation for a world alive with connection, meaning, and potentially infinite upside. We have the rare privilege of living at a time when our actions can shape the entire trajectory of the future. The blockchain renaissance has already expanded our sense of what's possible. Now it's on us to channel that newfound freedom towards a more beautiful and true reality.

The Path to Resonant Autonomy: Navigating Autonomy and Social Freedom in Web3

Space travel remains the dream of many people, and Intuitive Machines' has brought us one step closer. Although it “tripped” while landing on the Moon, Odysseus has managed to communicate with its control team on Earth, beaming back information and images. Odysseus is the first private spacecraft ever to land successfully on the moon — and the first American vehicle to do so since the final Apollo mission in 1972. Odysseus lander Of course, the Moon is probably only meant to serve as a practice pad and “truck stop” in the future for more ambitious missions that will take humans to Mars and elsewhere. The Moon will hopefully be used for scientific experiments, training purposes, and as a way station for future astronauts who will spend lengthy periods of time in space. While the Odysseus was unmanned, NASA has plans to send astronauts back to the Moon through its Artemis program. Billionaire and SpaceX founder Elon Musk he believes that humans could already be making their way to the red planet in just a few years. said last year Musk an ambitious plan to establish a human colony on Mars and that he aims to transport one million people to the Red Planet, stating that “civilization only passes the single-planet Great Filter when Mars can survive even if Earth supply ships stop coming.” In the past, Musk has said he plans to have a million people on and that “a on the red planet could sustain our species if all humanity is extinguished on Earth.” recently revealed Mars by 2050 permanent colony Musk has long voiced his intent to make humanity multi-planetary, often pointing to human settlement on Mars as an insurance policy for civilization in case Earth is struck by any number of calamities. With the space race in full gear, the question of who gets what contract has become a matter of serious competition. Companies like Intuitive Machines, Musk’s SpaceX, Amazon founder Jeff Bezos’ Blue Origin, or Richard Branson’s Virgin Galactic are all competing for the eventual ability to ferry Earth’s inhabitants back and forth between our planet and whatever way station or permanent habitat we build elsewhere, whether on the Moon or Mars. SpaceX's first priority is "establishing a cargo route to Mars," in the past. Musk has said Musk is relying on the much-touted Starship to advance his plans. His early plans involved sending unmanned ships to the surface of Mars and then sending people after that once the flights were proven safe. The first missions would work to convert water and CO2 found on the Mars surface into the liquid oxygen and methane fuel that powers the Starship. By doing so, SpaceX would guarantee a long-lasting fuel source. Once refueled, the Starships would be able to make the journey back to Earth. Following the initial flights, Musk wants to bring large groups of people to Mars to build colonies and factories to make the planet self-sustaining. One of the main priorities would be to build a factory for rocket fuel, essentially turning Mars into an outpost for ever-expanding space travel. In Musk’s vision, people could go from Mars to the asteroid belts, the moons of Jupiter and Saturn, and the Kuiper belt. While in the beginning stages, people on Mars would have to live inside large protected air-tight structures on the surface or even underground, eventually, though, Musk said he envisions having the ability to warm the planet to make it habitable and allow humans to live outside without the need for supplemental oxygen. But this is where some scientists begin to see problems with Musk’s grand plan. According to experts, there just on Mars that you can mobilize and create a long-lasting atmosphere the way Musk believes he can. The other problem, even if this was possible, is keeping the CO2 contained in the atmosphere. isn't enough CO2 Musk has said he understands this issue and realizes it would take a long time. He acknowledged that this is a project that would span several generations, and even if we cannot create an atmosphere now, we could at least build the first colony on Mars, preparing the way for future generations. One of the greatest advantages of space exploration in today’s day and age is that we now have new technologies, such as artificial intelligence (AI), to expand our capabilities more than was possible when space travel first became possible. For instance, AI is to help scientists analyze data more quickly and accurately and automate operations on spacecraft. The continuous development of other planets and moons in ways never before possible. currently being used in the space industry AI is helping rovers and landers explore “SpaceX has been improving and refining how rockets operate. The company uses AI to monitor and analyze data from the rocket’s sensors and telemetry systems, allowing for better decision-making and more precise control of the rocket’s trajectory and speed. SpaceX also uses AI to automate certain aspects of the rocket landing procedure.” NASA’s Jet Propulsion Laboratory has also recently developed an that can autonomously plan a spacecraft mission based on given parameters and constraints. Machine learning algorithms are being used to identify potential water sources or mineral deposits on the planet’s surface. AI-based mission planning system Clearly, AI is essential to the future of space exploration and will increasingly be implemented across various future missions in space—from Mars colonization efforts to interplanetary travel to supporting astronaut health. We are getting closer to this vision of becoming an interplanetary species. As long as it does not hallucinate or generate false information, as some AI technologies currently do, AI will help us achieve this unique and incredible vision.

ANALYSIS AND VALIDATION 3.1. Stellar Host Characterization 3.1.1. Semi-empirical Stellar Parameters We constructed the spectral energy distribution (SED) of EPIC 249631677 using photometric magnitudes from Gaia (GBP and GRP ; Gaia Collaboration et al. 2018) and the AllWISE source catalog (J, H, Ks, W1, W2, and W3; Cutri et al. 2013). The corresponding fluxes for these magnitudes are tabulated on VizieR (Ochsenbein et al. 2000) and shown in Figure 5 and Table 1. The parallax of EPIC 249631677 is π = 17.61 ± 0.09 mas, which yields a distance of 56.8 ± 0.3 pc (Gaia Collaboration et al. 2018; Stassun & Torres 2018). We then derived the stellar luminosity L∗ by integrating over the SED, which yielded L∗ = 0.0041 ± 0.0001L . Two independent methods were applied to obtain stellar mass. First, we used the empirical M∗−MKs relation (applying the metallicity obtained in Section 3.1.2) from Mann et al. (2019) to obtain M∗ = 0.1721 ± 0.0044M . We also applied stellar evolution modeling, using the models presented in Fernandes et al. (2019), using as a constraint the luminosity inferred above and the metallicity derived in Sect. 3.1.2). We considered the stellar age to be >1 Gyr in the absence of signs of youth, such as presence of prominent flares (Ilin et al. 2019, see Section 3.1.3). We obtained with this method M∗ = 0.176 ± 0.004 M . This uncertainty reflects the error propagation on the stellar luminosity and metallicity, but also the uncertainty associated with the input physics of the stellar models. We combined these two mass estimates as in Van Grootel et al. (2018) to obtain M∗ = 0.174±0.004M as our best estimate for the stellar mass of EPIC 249631677. Given its proximity, we expect minimal extinction (Av) for the target; the SED fitting analysis described in Section 3.2.1 similarly constrains it to be 0.02 at 3σ confidence and we adopt that upper limit here. Finally, we note that given its luminosity, mass, and Gaia colors this star is likely to be fully convective (Jao et al. 2018; Rabus et al. 2019). Due to the absence of a strong constraint on the stellar density from the transits, we further obtained stellar radius, surface gravity, effective temperature and density from our evolutionary models. Table 1 summarizes the results from this analysis, along with other properties of the star. Our values are consistent with those listed in the TESS Input Catalog (Stassun et al. 2019), and we adopt them for the remainder of this analysis. 3.1.2. Reconaissance Spectroscopy To confirm EPIC 249631677’s stellar properties and better characterize the system, we acquired an optical spectrum using Keck/HIRES (Vogt et al. 1994) on UT 30 May 2020. The observation took place in 0.6 00 effective seeing and using the C2 decker without the HIRES iodine gas cell, giving an effective resolution of λ/∆λ ≈ 55, 000 from 3600 ˚A to 7990 ˚A. We exposed for 1800 s and obtained SNR of roughly 23 per pixel. Data reduction followed the standard approach of the California Planet Search consortium (Howard et al. 2010). We used our Keck/HIRES radial velocity and Gaia DR2 data to estimate the 3D galactic (UV W) space velocity using the online kinematics calculator[2] of Rodriguez (2016). Following Chubak et al. (2012), our Keck/HIRES spectrum gives a barycentric radial velocity of 6.25±0.17 km s−1 . With the Gaia-derived coordinates, proper motion, and distance listed in Table 1, we find (U, V, W) values of (−17.02, −9.06, +33.66) km s−1 , indicating a likely membership in the Milky Way’s thin disk (Bensby et al. 2014). Using the SpecMatch-Empirical algorithm (Yee et al. 2017), we derive from our HIRES spectrum stellar parameters of Teff = 3195 ± 70 K, R∗ = 0.23 ± 0.10R , and [Fe/H]= −0.24 ± 0.09, consistent with the values tabulated in Table 1. The three best-matching stars in the SpecMatch-Empirical template library are GJ 15B, GJ 447, and GJ 725B, which have spectral types of M3.5V, M4V, and M3.5V, respectively. Given the close match between the spectra of these stars and our target (see Fig. 4), we therefore classify EPIC 249631677 as an M dwarf with subclass 3.5±0.5. We see no evidence of emission line cores at Hα, consistent with our determination that our target is not a young star. We see no evidence of spectral broadening compared to these three stars (which all have v sin i < 2.5 km s−1 ; Reiners et al. 2012), so we set an upper limit on EPIC 249631677’s projected rotational velocity of < 5 km s−1 , comparable to the spectral resolution of HIRES. 3.1.3. Stellar Variability The long-term variations apparent in the everest light curve (Figure 1) are not evident in light curves from other reduction pipelines (e.g., K2SFF). These variations likely arise from systematics and are not reliable for estimating the stellar rotation period (Esselstein et al. 2018). Similarly, no flares are apparent either in the K2 or SPECULOOS data. Flare rates peak for ∼M3.5 stars in TESS data (G¨unther et al. 2020). However, given the long integration time of 29.4 minutes as well as a need for data processing which corrects for the saw-tooth pattern, flare signals, unless very prominent, are expected to be difficult to detect in K2 long cadence data. 3.2. Vetting In order to produce a transit depth on the level of 0.2% in the light curve of the primary target, a background eclipsing binary producing eclipses with depths of 25% to 50% would have to be 5.25 to 6.0 mag fainter than the target, respectively. Qualitatively, the odds of EPIC 249631677 hosting a planet are higher than the odds of such magnitude contrast eclipsing binary being present within the SPECULOOS aperture, given occurrence rates of M-dwarf planets (Dressing & Charbonneau 2013; Mulders et al. 2015; Hardegree-Ullman et al. 2019). A stringent quantitative constraint can be placed using the ingress/egress duration (T12/T34) compared to the total transit duration (T14) (Seager & Mall´enOrnelas 2003, Equation 21). Such a test yields an upper limit on the relative radius of the transiting body. By assuming equal effective surface temperatures, the lower magnitude limit ∆m (corresponding to a flux difference ∆F) for a blended binary mimicking a signal of depth δ is given by: Using the posterior for the transit fit (See Section 3.3), we find for EPIC 249631677 that such a background object can be fainter at most by 1.73 mag at the 3σ level. Fortunately, EPIC 249631677 has a significant proper motion, ∼140 mas yr−1 , which allows us to investigate the presence of background sources at its current sky position. We looked at archival imaging of EPIC 246331677 going back to 1953[3] . A POSS I plate from 1953 is the publicly available oldest image of EPIC 249631677, and it does not show any background source at the current position of the target as shown in Figure 6. The plate is sensitive to objects at least 3.5 magnitudes fainter than the target. Similarly, the Hubble Guide Star Catalogue (GSC), with a limiting magnitude of 20 (Lasker et al. 1990), does not show any background source. While POSS II would go the deepest in terms of limiting magnitude (20.8, Reid et al. 1991), the star has moved appreciably closer to its current location, precluding a definitive measurement from this image. Overall, using archival images we can rule out the possibility of the transit signal originating from background star at a high level of confidence. 3.2.1. Binarity of the Host Star Despite the lack of background sources, the host star could produce a false-positive transit signal if it were a grazing eclipsing binary or a hierarchical eclipsing binary. We investigated the evidence for host star binarity using the isochrones software package (Morton 2015), which performs isochrone fitting in the context of the MESA (Paxton et al. 2011, 2013, 2015) Isochrones and Stellar Tracks database (Dotter 2016; Choi et al. 2016). Single-star and binary evolutionary models are available within isochrones, and the inference is performed via the nested sampling algorithm MULTINEST (Feroz et al. 2009) (as implemented in the PyMultiNest software package (Buchner et al. 2014)), which allows for direct comparisons of the Bayesian evidence ln Z. We tested both single-star and binary models using the priors on photometric magnitudes and stellar distance described in Section 3.1.1. The inferred properties from the single-star model fit are consistent with those given in Table 1 at the 2σ level. The ln Z for the single-star model is −213.86±0.04, whereas the ln Z for the binary model is −229.6 ± 0.2. According to Kass & Raftery (1995), the corresponding Bayes factor of 16 indicates “decisive” evidence in favor of the single-star model. We also examined our Keck/HIRES spectrum for secondary lines that would indicate the presence of another star following the approach of Kolbl et al. (2015). We found no evidence of additional lines down to the method’s standard sensitivity limit of ∆V = 5 mag for ∆v > 10 km s−1 , consistent with EPIC 249631677 being a single, isolated star. We therefore conclude that the available data strongly support EPIC 246331677 being a single star. 3.2.2. Photometric Tests We performed a series of tests on the photometric data to rule out false-positive scenarios. First, we performed an even-odd test on the target using K2 photometry. The even and odd transits are consistent with one another in transit depth to within 1σ. We also looked for secondary eclipses in the phase-folded light curve and found none to be present. Note that since we observe consistent signals in both the K2 and SPECULOOS data sets, we can rule out the signal originating from systematics. The transit depth in SPECULOOS observations with I+z filter, which is redder than Kepler bandpass, are consistent to K2 transit depths within 1σ level, keeping up with the expectation of the achromatic nature of planetary transit. Furthermore, a massive companion, such as a faint white dwarf, can be ruled out using the ellipsoidal variation, which puts a 3σ upper limit on the mass of any companions at the given orbital period of the transit signal as ∼100 MJup (Morris 1985; Niraula et al. 2018). From the transit fit, we can rule out a grazing eclipse originating from a larger transiting object (i.e. ≥ 2R⊕) at >3σ confidence. Together, these tests rule out the object at 3.14 days being a massive companion. 3.3. Transit Fitting We used the refined estimates of the host properties together with a joint analysis of the K2 and SPECULOOS light curves to derive the planetary properties. In order to calculate the transit model, we used batman (Kreidberg 2015). We simultaneously model both the K2 observation as well as the ground-based observations with 21 parameters in a Monte Carlo Markov Chain (MCMC) framework using the emcee package (ForemanMackey et al. 2013). We use a Gaussian prior on the scaled semi-major axis of the orbit a/R∗ of N (25.72, 0.27), derived using Eq. 30 from Winn (2010) along with the stellar density of 32.6 ± 1.0 g cm−3 (see Section 3.1.1) and orbital period of 3.1443 days from the TLS search. As for the limb darkening, we use the non-informative q1, q2 parameterization of the quadratic limb-darkening law as suggested by Kipping (2013). We fixed the eccentricity to 0, given that the expected time of circularization is 50 Myr (assuming a quality factor Qp ∼ 500, Goldreich & Soter 1966; Patra et al. 2017), which is at least an order of magnitude smaller than the estimated age of the system. For K2 data, we supersample the transits by a factor of 15 in batman to take into account the effect of non-negligible integration time. As for the ground-based data, we use second-order polynomials to detrend against the observables airmass and FWHM. We ran the MCMC for 50,000 steps with 150 walkers performing a combined fit of K2 and SPECULOOS — (1) This work. (2) Huber et al. (2016). (3) Stassun et al. (2019). (4) Cutri et al. (2003).

As we step into 2024, the Non-Fungible Token (NFT) industry, is ripe for a satirical forecast. Here are ten humorous and exaggerated predictions for the NFT market in 2024, where reality often seems stranger than fiction. 1. Donald Trump's Wall Builder NFT Series: A Virtual Political Statement In a unique blend of real estate and politics, former President Donald Trump's entry into the NFT market in 2024 will take a captivating turn. A major NFT series is set to be released: the controversial "Wall Builder" NFT series. In a move that is sure to stir both support and outrage, the "Wall Builder" NFT series will be Trump’s digital nod to one of his most infamous proposals – the border wall. Each NFT in this series represents a section of the virtual wall, with designs ranging from imposing fortresses to avant-garde barriers. Owning a Wall Builder NFT comes with unique virtual titles like "Digital Border Patrol Chief" or "Virtual Wall Inspector," allowing holders to partake in simulated border patrol missions. These missions are gamified experiences, complete with rewards, leaderboards, and exclusive digital merchandise. 2. Interstellar NFTs: NASA, Elon Musk, and the Cryogenic Conundrum In 2024, NASA, in collaboration with Elon Musk and a leading blockchain company, announces the launch of Interstellar NFTs. These digital assets represent ownership of land on distant exoplanets, blending the frontiers of space exploration with blockchain innovation. Each NFT offers buyers a stake in otherworldly real estate, complete with intricate digital depictions and detailed planetary profiles. Elon Musk, ever the visionary, adds an intriguing twist to the narrative. He promises to greet the NFT owners upon their arrival on these distant planets in the year 3024. The public is left speculating on the nature of Musk's presence: Will he be there in human form, having triumphed over aging through cryogenic freezing (only available via buying an NFT), or will he welcome them as a digital avatar, an immortal representation of his pioneering spirit? This conjecture fuels a mix of fascination and humor, with people playfully debating whether they'll meet an age-defying Musk in the flesh or interact with his advanced AI doppelgänger. 3. Time Travel NFTs Break All Sales Records The "Temporal Passports NFT" series, launched in 2024, has shattered all previous NFT sales records but not for reasons one would expect. Intended to transport holders to the era of their token's depicted historical figure, the series instead gained fame for its humorous technical glitches. Users anticipating accurate historical immersions were amused to find themselves in wildly mismatched time periods. For example one NFT holder, armed with a George Washington NFT and expecting a Revolutionary War scene, ended up in the roaring 1920s, quipping, “Instead of crossing the Delaware, I crossed into the Jazz Age. At least the booze is better.” This unpredictability turned the Temporal Passports into a unique profiting sensation, with holders being able to stake their NFTS and able to rent out their NFTs to other history buffs. 4. The Capitol Coin DAO: The White House Launches a DAO In 2024, as the U.S. political landscape dives into the world of blockchain with the launch of the "Capitol Coin DAO," the corridors of power get a digital makeover. In the Capitol Coin DAO, influential lobbyists and billionaire donors find themselves in a familiar position, but with a twist. Known as the 'Whales of Politics,' these power players attempt to sway decisions by accumulating vast amounts of Capitol Coins. However, they quickly realize that in the world of DAOs, money can't always buy consensus. In a comedic turn of events, a group of high school students, using only their lunch money and bags of SHIB, outvote a major lobbying effort, proving that in the DAO, quantity of coins doesn't always trump the power of collective decision-making. To combat the potential for manipulation, the Capitol Coin DAO introduces a series of humorous but effective measures. One such measure is the "Filibuster Feature," where any proposal that seems suspiciously advantageous to the 'Whales' is automatically subjected to a 24-hour meme bombardment, questioning its legitimacy. 5. Trump's NFT Gambit for Eternal Presidency In an unexpected yet somehow predictable move, former President Donald Trump jumps on the DAO bandwagon, launching his own NFT collection titled "Trump's Triumphs." He claims that anyone holding the complete set of these NFTs can unlock a secret feature in the Capitol Coin DAO, granting them "Permanent Presidency" powers. The Capital Coin DAO quickly blocks any attempts at a hostile takeover and as a result. Undeterred by this setback and true to his indomitable style, Trump pivots to create his own digital domain, the "TrumpVerse." Here, he proclaims himself as the perpetual president, a role unbound by the constraints of traditional politics. Supporters and collectors alike can buy virtual land in the TrumpVerse giving them the chance to own a piece of this exclusively Trumpian digital world. 6. Mortgaging Reality for Virtual Acres As 2024 rolls around, a bizarre economic trend sweeps across the nation. With real estate prices sky-high and interest rates climbing, homeowners start mortgaging their physical homes, not for a bigger backyard or a better neighborhood, but for a slice of virtual land in the ever-expanding metaverses. The craze for virtual land is driven by a mix of escapism and speculative investment. Enthusiasts argue that owning a piece of digital paradise is a wise move, free from the constraints of physical maintenance and pesky property taxes. Some even boast about their virtual mansions, complete with artificial intelligence butlers and virtual reality gardens, all financed by the equity in their modest three-bedroom bungalow. As more people jump onto the virtual land bandwagon, economists begin to warn of a 'Surreal Estate Bubble.' Late-night show hosts quip about the absurdity of people living in cramped apartments while owning virtual estates, with one joking, "In the Metaverse, everyone can hear you brag, but no one can help you move your virtual couch." 7. Home Depot's MetaDepot: Revolutionizing Virtual Home Renovation In an innovative twist in 2024, Home Depot launches "MetaDepot," a series of NFT Metaverse stores dedicated to virtual home improvement. This move taps into the burgeoning trend of digital homeowners needing to renovate and enhance their virtual abodes. At MetaDepot, customers find themselves in a surreal world of home renovation, specifically tailored for the Metaverse. Gone are the days of physical paint and lumber. Instead, virtual homeowners purchase NFTs representing digital wallpaper, ethereal lighting fixtures, and even holographic furniture to spruce up their online properties. 8. Senator Warren's NFT Escapade: From Political Pundit to NFT Artist In an unexpected turn of events, Senator Elizabeth Warren, known for her critical stance on cryptocurrencies, launches a Profile PFP NFT Meme series in 2024. The collection, infused with rare NFTS that are a nod to her controversial Native American ancestry, becomes an instant hit. But it's the climactic use of her NFT fortune that cements her place in the annals of political satire. Thwarting the Whale with Capitol Coin DAO Cashing in on her NFT success, Warren invests in Capitol Coin DAO Tokens, aligning herself with a group of astute high school students who have become influential players in the DAO who hodle a large amount of tokens from pooling their lunch money and selling their SHIB bags. Together, they engineer a masterful move to thwart a major lobbying effort by a "Whale," a wealthy player attempting to sway decisions with sheer financial power. This David versus Goliath scenario plays out on the digital stage, with Warren and the students championing the power of collective action over deep pockets. The plot thickens when one of the high school students, armed with insights from the DAO and a cunning use of Reddit, manages to ascend to an unprecedented level of political influence. In a stunning development, this savvy teenager leverages their digital prowess to make a bid for the presidency – and wins. The political world is left in shock as a Reddit-savvy, DAO-empowered student with lunch money and SHIB takes the highest office in the land. In the wake of this surreal turn of events, Senator Warren decides to hang up her political gloves. She retires from the world of policy and legislation, but not from the public eye. Warren turns her attention to creating NFT art, drawing on her experiences and the whirlwind events she helped catalyze. Her art, known for its blend of political satire and digital innovation, becomes highly sought after, turning her into a surprising yet successful figure in the NFT art world and a keynote speaker at NFT.NYC and Art Basel. 9. Interstellar NFTs: NASA and Elon Musk's Galactic Real Estate Gamble In a partnership that stretches the bounds of imagination, NASA, in collaboration with Elon Musk's space exploration company, launches Interstellar NFTs in 2024. These NFTs represent a bold venture into digital ownership of land on distant exoplanets, blending the allure of space exploration with the burgeoning world of blockchain. Each NFT offers virtual rights to a plot on an alien world, complete with artistically crafted visuals and detailed planetary descriptions. The most captivating aspect of this venture, however, is the promise that owners of these NFTs will have the opportunity to visit their interstellar holdings when space travel to these distant planets becomes possible – a feat optimistically slated for the year 3024. Adding to the intrigue, Elon Musk playfully assures potential buyers that he will personally greet them on their new cosmic properties, sparking widespread amusement and speculation about the longevity and future ambitions of the tech mogul. 10. Emotional Ownership NFTs: Claiming History's Feelings In 2024, a groundbreaking initiative by a leading tech company introduces a new genre of NFTs – "Emotional Ownership" of historical events. This novel concept allows individuals to own the exclusive rights to the emotions associated with significant moments in history. It’s an audacious blend of technology, sentimentality that captures the public's imagination. Imagine having the exclusive NFT that represents the collective joy felt during the 1969 moon landing. This NFT wouldn’t just be a digital token; it would symbolize your personal connection to the euphoria and wonder that enveloped the world as humanity took its first steps on the lunar surface. Each NFT comes with a beautifully designed digital certificate, detailing the event and the specific emotion it encapsulates. NFT holders question the practical implications of owning such NFTs and what rights the holders have. “Do I get royalties every time someone feels inspired by the Wright Brothers' first flight?” one user quips. Another posts, “Just bought the NFT for ‘surprise’ at the Boston Tea Party. “If someone reenacts the Tea Party, do I get to sue for emotional trespassing!” *** As we reflect on the remarkable developments in the world of NFTs and digital assets throughout 2024, it's clear that we are witnessing a period of unprecedented innovation and creativity. Here's to the innovators who dare to dream big, the communities that come together to turn these dreams into reality, and the endless possibilities that the future holds. Cheers to 2024! Audrey
