Even if you already took our first survey, you can help us improve Astrobites even more by taking our second very brief reader survey. There are just 6 short questions and it will only take a couple minutes.
We’re starting a new section of Astrobites we’re calling “Glossaries”. The first of these glossaries, on Galaxies and AGN, is now available.
Compositional investigations of comets have suggested that they are “icy dirtballs,” so would it be possible to detect traces of hydrogen and oxygen if they were flung from one stellar system into the atmosphere of another star?
Each galaxy in the sky will probably produce just one or two supernovae in our lifetimes, so you have to be lucky to spot one. But if you happen to be observing hundreds of thousands of galaxies anyway, you’re bound to catch a few.
