A Runaway Star in the Small Magellanic Cloud

4 April 2018

In a drama taking place in the Small Magellanic Cloud, a close companion galaxy to the Milky Way, a rare star is speeding out of the galaxy at 300,000 miles per hour. The first runaway yellow supergiant star ever discovered, and only the second evolved runaway star found in another galaxy, the star was once a member of a binary star system and was ejected at high speed when its companion star exploded as a supernova. The discovery was made using the CTIO 4-m Blanco telescope.
