Hubble has discovered rocky remains of planetary material 'polluting' the atmospheres of two white dwarfs. Continue reading →
What happens when you combine a white dwarf with an M dwarf star? A possible answer to a supernova mystery.
Given their withering radiation and tidal stresses, white dwarfs are unlikely places to go looking for inhabited worlds -- but don't rule them out either.
White dwarfs may technically be the remnants of dead stars, but could they provide a steady, long-term energy source to alien life?

These two stellar siblings don't seem to like each other very much. But it's OK, they make up in the end.
