Nearby supernova 30M years ago equaled detonation of 100 million suns
Dallas TX (SPX) May 03, 2016
A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, according to astrophysicists at Southern Methodist University, Dallas. The sudden blast hurled material outward from the star at a speed of 10,000 kilometers a second. That's equivalent to 36 million kilometers an hour or 22.4 million miles an hour, said SMU physicist Govinda Dhungana, lead author on the new analysis. The comprehensive analysis ... read more
