Nearby massive star explosion 30 million years ago equaled brightness of 100 million suns

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, say astrophysicists at SMU.

The massive explosion, Supernova 2013j, was one of the closest to Earth in recent years. Analysis of the exploding star’s light curve and color spectrum found its sudden blast hurled material from it at 10,000 kilometers a second. Continue reading

Observed by Texas telescope: Light from huge explosion 12 billion years ago reaches Earth

Gamma Ray Burst, SMUIntense light from the enormous explosion of a star more than 12 billion years ago — shortly after the Big Bang — recently reached Earth and was visible in the sky.

Known as a gamma-ray burst, light from the rare, high-energy explosion traveled for 12.1 billion years before it was detected and observed by a telescope, ROTSE-IIIb, owned by Southern Methodist University, Dallas. Continue reading
