Light from two massive stars that exploded hundreds of millions of years ago recently reached Earth, and each event was identified as a supernova.
A supernova discovered Feb. 6 exploded about 450 million years ago, said Farley Ferrante, a graduate student at Southern Methodist University, Dallas, who made the initial observation.
The exploding star is in a relatively empty portion of the sky labeled "anonymous" in the faint constellation Canes Venatici. Home to a handful of galaxies, Canes Venatici is near the constellation Ursa Major, best known for the Big Dipper.
A second supernova discovered Nov. 20 exploded in one of the many galaxies of the Virgo constellation. It exploded about 230 million years ago, said Ferrante, who made the initial observation.
Both supernovae were spotted with a telescope at the McDonald Observatory in the Davis Mountains of West Texas near Fort Davis. Read the full story at http://bit.ly/V5T43Z.
