. Astronomers think gamma-ray bursts may be linked to black holes but aren't sure of the exact circumstances of their creation. One idea is that gamma-ray bursts are produced after a massive star explodes and leaves a black hole in its place. Another idea is that they're produced when two neutron stars collide to form a black hole. The appearance of a gamma-ray burst is unpredictable, but one appears about once per day. ESA / ECF

Seven months ago, on Mar 19, 2008, at 09:12 Moscow time, a new star appeared on the sky. The Sun had already risen over the Russia, but people of the Western hemisphere might be able to see by their eyes a faint starlet near one of Bootes constellation stars. This starlet appeared and faded by an order of magnitude in a minute. Astronomers named it GRB080319B or, informally, the Naked-Eye Burst, as it was twice as bright as human eye can see a star. ...
