Lonely Supernova Likely Exiled by Merging Black Holes

Isolated supernovae, exploding alone in the empty space between galaxies, may be the result of star pairs ejected from their homes as galaxies merge, new research suggests. "This story has taken lots of twists and turns, and I was surprised every step of the way," Ryan Foley, principle investigator of the new study, said in a statement from the Hubble Space Telescope news center.
