Exoplanets Dont Like Heavy Metals

8th Nov, 2018 - 1.3k views

Studies of planetary systems have indicated that star systems with high metallicity (think iron - actually anything heavier than helium) may preferentially form planets,but a new survey suggests there are many compact, multiple-planet systems for whi

The mission engineers and scientists for the Hubble Space Telescope have been working to correct some technical issues with the gyros that point the venerable space telescope. Hubble went into safe mode a couple of weeks ago and now seems to be back

New Evidence for a Large Exomoon around Kepler-1625b

10th Oct, 2018 - 1.5k views

Astronomers using Hubble Space Telescope data have new observations of a candidate exomoon associated with Kepler-1625b. If confirmed, this exomoon would be quite large, with a mass and radius similar to Neptune. The exoplanet Kepler-1625b is itsel

Have Astronomers Found Vulcan?

Live chat on Discord! https://discord.gg/nqGpvtK What would the planet Vulcan be like? It might be like the "super-Earth" planet orbiting a nearby star (16 light years) called HD 26965. The planet is only 2 times the size of Earth and the parent sta

Mars: Warmer with Water - Was it once Closer to the Sun?

10th Sep, 2018 - 1.1k views

The study of planetary systems around other stars suggests that planets can migrate closer or farther from their parent star, not staying in the orbit where they originally formed. Traces of water on Mars suggests that it may have been wetter, and pe

Climate Change on Alien Worlds: A Possible Great Filter? (Pt 2)

21st Aug, 2018 - 1.2k views

Is climate change inevitable on worlds with technological civilizations? Is planetary feedback from such a civilization a great filter? Our guest Dr Adam Frank will discuss his paper on the effects of planetary feedback on any possible alien civiliz

Finding Neutrinos with (an) IceCube

7th Aug, 2018 - 1.2k views

Super energetic neutrinos can be formed in exotic places, for example the accelerators in the core of galactic supermassive black holes. The IceCube neutrino detector array was built and deployed at the South Pole. The detectors are designed and posi

Climate Change on Alien Worlds -A Possible Great Filter?

24th Jul, 2018 - 1.3k views

While our search is still in its infancy, we haven't yet found any obvious signs of intelligent life in our galaxy. One reason could be that any aliens out there may not have made it past a stage in its development where climate change wipes them out
