Afternoon Astronomy Coffee

Every week, in universities and institutions around the world, astronomers meet over coffee to discuss the latest research in space and astronomy. This is your chance to join in on Thursdays, 3pm ET.

Exoplanets Don't Like Heavy Metals

6th Nov, 2018

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

Hubble Space Telescope Update

24th Oct, 2018

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

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?

26th Sep, 2018

Live chat on Discord! 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

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

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
