EUROPE: 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.
Foley and his colleagues studied massive stellar explosions that normally take place inside the confines of a parent galaxy, but were instead lighting up the sky between galaxies, presenting an ongoing puzzle for astronomers. What happened to the stars that created these explosions? How were they ejected them from their homes, and what caused them to explode? The researchers think they have some answers.
