Will Smith and his son Kitai are back in this highly anticipated, totally unexpected sequel and this time, they’ve crash landed on a Super-Earth. Surviving won’t be easy, but it might be even harder for the planet’s atmosphere.
Planets are km-size bodies, but it is particularly puzzling how solid grains have grown to sizes beyond cm to m. Water ices can improve the sticking of such grains, but does this imply that ices from other molecules improve the sticking as well?
How can we find other pale blue dots? Today’s paper studies what could be the most time-effective way to search for Earth-like exoplanets, just by looking at their colors.
For several years now, there has been considerable interest in circumbinary planets – that is to say, planets that orbit both stars in a binary system. They pose many interesting questions, such as, “How does their formation differ from planets in single-star systems?”, “What will happen to them when the stars evolve?”, and of course, “Could humans live there?” It was because of questions like these that the authors of today’s paper turned their telescopes on KIC 7177553.
Sherlocks Holmes investigates the scene of a crime for clues about whodunit. Today’s paper investigates the massacre of circumstellar disks in a star cluster for clues about the cluster itself.
Planets can live very close to one another, but are planetary neighbors destructive to life, or might they help it get started in the first place?
