Recently, several supernovae have been observed that do not fit in any of the known categories. These Calcium-rich supernovae are challenging to explain, but in this astrobite you read that they are likely the result of an expelled merger.
Astrophysics covers a huge amount of scales from subatomic size to the size of the universe. Nevertheless, it is often possible to describe fundamental phenomena only with the help of few equations – although doing the calculations may reveal surprises.
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?
More than a year ago, scientists managed to land on a comet for the very first time in human history. Read on to get a compact overview of some of the most important results of the mission obtained so far.
Planets with radii between Earth and Neptune and small radii are the most common in planetary systems. These planets are challenging to explain with classical models of planets. Do planets form instead in-situ in an inside-out manner?
