What do we know about the second object to visit us from another stellar system? Detailed Hubble images have given us plenty to consider!
Remember KIC 8462852, better known as Boyajian’s star (or you may have seen it referred to as the “alien megastructure” star)? We still don’t have a definitive explanation for this source’s odd behavior — in part because we thought that Boyajian’s star was one-of-a-kind.

What causes the bizarre, extragalactic fast radio bursts we’ve detected over the last decade? An unusually bright supernova may hold the answer.
Humanity’s search for signs of extraterrestrial intelligence has been underway, in one form or another, for decades. But how much searching have we really done?
A recent study has discovered three of the fastest stars — white dwarfs — known in the Milky Way. But these stars may be more than just speeders — they might also be evidence of how Type Ia supernovae occur.
