There’s an unexpected population of blue stars identified in clusters, known as blue stragglers. They should have evolved off the main sequence, but some rejuvenating process is in action, keeping them there longer than expected. Their origin and evolution is not fully understood. Today’s paper tackles these two issues, identifying some possible answers as to where these blue straggler stars come from and where they are going.

A new look at Saturn’s windy weather.
A classic paper on dark matter is brought to ‘light’ in this bite, discussing a discovery that provides one of the best evidences we have for non-baryonic matter in the universe.
Today, we’re taking a look at a recently discovered planet, which is almost 10,000 light years away from Earth, and as such one of the most distant planets ever discovered.
Today’s astrobite explores one of the most extreme distant galaxies: a dusty, star forming galaxy at redshift 5.7 which has been found to have one of the highest star formation densities of any known galaxy in the Universe. But what causes this? Does it contain an active galactic nucleus?
Five young stars in one system — all the same age but at different stages of their evolution. What can they tell us?
