Three Stars Banished From Their Galaxies, Explode in Deep Space

Three stellar exiles exploded in solitude hundreds of light-years away from their closest cosmic neighbors, it was revealed this week
Supernova — giant exploding stars at the end of their lives — are usually embedded within galaxies that play host to billions of stars. But new data from the Hubble Space Telescope confirms that three stars went supernova alone, in the void between galaxies in different clusters
These huge star explosions could give scientists a better idea of what happens in those mysterious, empty areas of space between galaxies.
The three errant supernova were first discovered between 2008 and 2010 by using a telescope on Mauna Kea in Hawaii. But the Hubble's more recent, sharper observations revealed more about the three supernova.
