Mysterious cosmic explosion puzzles astronomers
LIGO’s twin black holes might have been born inside a single star
On 14 September 2015, the Laser Interferometer Gravitational-wave Observatory (LIGO) detected gravitational waves from the merger of two black holes 29 and 36 times the mass of the Sun. New research suggests that the two black holes might have resided inside a single, massive star whose death generated a gamma-ray burst detected by the Fermi Space Telescope.

NASA’s Swift spots its thousandth gamma-ray burst
NASA’s Swift spacecraft has detected its 1,000th gamma-ray burst (GRB). A GRB is a fleeting blast of high-energy light, often lasting a minute or less, occurring somewhere in the sky every couple of days. GRBs are the most powerful explosions in the universe, typically associated with the collapse of a massive star and the birth of a black hole.
Final kiss of two stars heading for catastrophe
Using ESO’s Very Large Telescope, an international team of astronomers have found the hottest and most massive double star with components so close that they touch each other. The two stars in the extreme system VFTS 352 could be heading for a dramatic end, during which the two stars either coalesce to create a single giant star, or form a binary black hole.
