  1. The aftermath of Winter Storm Harper has made it hard to predict whether or not it’ll clear up in time for the eclipse, but as of now, it seems like it is clearing and will stay (mostly) clear. I wonder how the moisture in the atmosphere will impact how red the moon gets from my vantage point, since low moisture and high levels of dust are known to make it darker red.
  2. Winter Storm Harper wasn't a big snowmaker for where I live, but it glazed EVERYTHING in ice, which has made for some really cool photography opportunities.
  3. You’re lucky. I’m not too sure if the sky will clear up quickly enough for me to see the Moon when it’s in the umbra.
  4. 10 F is the actual temperature; I don’t know the exact wind chill prediction for Monday, but I’ve been hearing around -20 F. Do you live in New England as well?
  5. It’s lucky that it’s still even somewhat active after over two years. I’m also getting stuff from Winter Storm Harper, but not much. Likely 3-5”, maybe 5-8” if I’m lucky. However, temperatures will drop to no more than 10 F for Monday, and it may clear up quick enough Sunday night to see the total lunar eclipse.
  6. R/Prequelmemes: “r/StarWars just circlejerks in whatever is the thing that mean Disney Is Evil, without looking into what the facts actually are”. Look who’s talking. (And yes, that is an actually quote from Prequelmemes just a few days ago after everybody went berserk over Warner Chapell copyright striking that Vader fan film because they thought it had copyrighted music. Jeez, people need to calm down.)
  7. Considering how much pressure is stuck under the surface due to tidal forces, it’ll be impossible to plug the old volcanoes without leading to new ones forming. Even if you did manage to clog all of them up, you’d just lock up even more pressure and risk causing even worse eruptions, and even if you avoid that, the radiation would cook you alive pretty quickly. After the success of Bird Box, I guess Netflix thinks they can get away with lazy writing if their movies have a concept interesting enough to get people talking about it. Just by the fact that they chose Io for their setting conf
  8. Tau Ceti will be observed by TESS, so if the inner planets transit, they should be detected. However, since all the planets are likely have inclinations similar to the system’s debris disk, they are unlikely to transit and would be much more massive. That doesn’t mean Tau Ceti e and f aren’t rocky. Lower metallicity stars are expected to have a harder time forming Mini-Neptunes and other gas planets because, due to the lack of heavier elements, it would take too long for planetary cores to form and get large enough to accumulate hydrogen atmospheres before the gas disk is blown away. That woul
  9. I hope we get more precise data on the Tau Ceti system soon, especially on the masses and orbital eccentricities of the planets. I’m pretty confident they’re all rocky because of the host star’s low metallicity (less metals = less likely for gas planets to form), even if Tau Ceti e and f end up being around 7-8 Earth masses as suspected, but better eccentricity estimates will be good to determine whether or not Tau Ceti e strays too close to be habitable. The PHL has also, after all this time, FINALLY updated K2-72e with its correct stellar flux, making it the most Earth-like planet ever
  10. EPIC 210693462 b has been confirmed as K2-288 Bb! https://www.jpl.nasa.gov/news/news.php?feature=7313
  11. LHS 3844 b could be around the higher range of 2.5-3.5 Earth masses because of its close proximity to the host star’s Roche Limit. Similar to K2-229b, it’s probably a dense iron planet. Also, I am not working on IA-Revived anymore. I just haven’t been able to get back to it, and I can’t even keep up with my newest mods. I have some good news: it looks like the TESS press conference will be happening tonight! It’ll start at 7:00 pm PST (10:00 pm EST), so it will probably be a little too late for me to watch it, but I should be able to watch the K2-138g press conference. It st
  12. In the talk starting at 10:15 am PST, the third section will be about K2-138g. Jessie Christiansen, one of the founders of Exoplanet Explorers, mentioned over the summer that she and her team had used Spitzer to detect a third transit of that planet, and their results will be presented tomorrow. However, it’s the section after that I’m most excited about: “A Small Transiting Planet Discovered by Citizen Scientists”. Ever since Jessie said on Twitter how multiple citizen scientist exoplanet finds would be announced at AAS 233, several of us over on Planet Hunters have been hoping one of them wo
  13. Something big is coming tomorrow... https://aas.org/meetings/aas233/2nd-media-advisory#press_conf
  14. Now I can’t unsee Ultima’s almost uncanny resemblance to BB-8.
  15. 11:30? I thought it was going to be around 2 or 3 pm EST, or did they move the image arrival time?
  16. Closest approach just flew by, New Horizons is speeding away and (hopefully) continuing to do science!
  17. Under two hours and 100,000 km to go!
  18. Probably even less than that. Tomorrow at around 2 or 3 pm EST, we should get the first few images showing the shape and, maybe, color of Ultima Thule. We will have to wait a few days for some of the best photographs, though, but anything that gives us any insight into what this ice potato is like is welcome.
  19. I think I can see signs that Ultima is a contact binary. It would be just as cool if it were a flatted football shape like Haumea. Also, it appears that we’re looking right down Ultima’s rotational axis, just as the NH team thought.
  20. My favorite launch this year would have to, of course, be TESS. Parker and BebiColombo are set to make amazing finds in the near future, but TESS is the one that started making incredible finds almost immediately — its first planet, Pi Mensae c, was confirmed just two months after observations began! Also, it’s an exoplanet mission, and it’s one I’m using to find planets, just like with Kepler/K2 (may you Rest In Peace). How could I not pick it? I honestly can’t decide between Hayabusa2, Osiris-REX, or InSight for my top space exploration mission of the year, but they would all be in the
  21. Only the TESS candidates I’ve found with LcViewer and Planet Hunters TESS. I primarily analyze K2 data, especially from the later campaigns (13, 14, 15, 16, and 18).
  22. I’m not too sure. Even if Barnard b does have the potential to host a Titan-like atmosphere, Barnard’s Star emits most of its light in the infrared, so I’m unsure of that could impact the composition of its planet’s atmosphere, or change whether or not hazes can exist. Also, the star is extremely metal-poor, which might determine what kinds of atmospheres can exist on any of its planets. Barnard’s Star is just about as different from the Sun as you can get, which means what’s possible in our solar system might, unfortunately, not be possible in its system.
  23. At that distance from its star, I would expect a Titan-like mix of nitrogen and methane, possibly even thicker than Titan’s atmosphere thanks to the higher gravity. Some other ices like ammonia will probably also be present in small amounts.
  24. K2-149h is probably too warm for liquid methane, but liquid ammonia can’t be ruled out, since it likely formed near or at its current location. The visual representation for it is actually a desert almost entirely covered in ice, which could be the case if the planet turns out to be smaller than I calculated.
