Astronomers Find a Bunch of ‘Monster Stars’ in Star Cluster

March 18, 2016

A group of astronomers probing a young star cluster within the ultraviolet section of the light spectrum just found a bunch of huge ‘monster stars.’ The R136 star cluster, located in the Tarantula Nebula, inside the Large Magellanic Cloud, is about 157,000 light years from Earth.

A Blast of Gamma Rays from Halfway Across the Universe Detected

December 16, 2015

Back in April 2015, a surge of high-powered gamma rays from half-way across the universe crashed into Earth’s atmosphere. But, according to the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, the burst of gamma rays didn’t put any of us in danger and produced no noticeable effects since the high-energy rays are blocked by Earth’s atmosphere. Astronomers, using […]
