The faraway bursts from outer space emit as much energy in a millisecond as the Sun does in about 10,000 years.A radio flash, one of many which have baffled scientists for nine years, has been traced to a galaxy six billion light-years from Earth. Fast radio burst (FRBs) are invisible to the human eye and last just a fraction of a second, emitting as much energy in a millisecond as the Sun does in about 10,000 years. It is not known what causes them - only 17 have been detected since 2007, even though more than 10,000 are thought to occur every day - and for years astronomers have been unable to discover where they come from. But now a team has for the first time traced one flash to the faraway galaxy in the constellation Canis Major. Some had speculated that the flashes might be signals from aliens but this has been ruled out by study lead author Evan KeaneĀ of the Square Kilometre Array Organisation. More likely is the possibility that the FRB, seen on 18 April last year, was the result of two ultra-dense neutron stars colliding.
