What secrets are hiding in the archives of the GALEX satellite?
We know that white dwarfs have planets, but there are very few that we have detected directly. An upcoming survey may change that.
A supernova that Tycho Brahe studied in 1572 may yet have something to tell us about what causes supernovae.
Today’s paper describes models of what a nearby supernova would do to a young planetary system, and looks at whether the same may have happened to our own solar system.
New data from Gaia shows that the white dwarf GD 50 is part of the co-moving group of stars AB Doradus. What does this tell us about the group?
