Alien spacecraft or merging black holes? Powerful radio bursts are from outer space, say scientists
Researchers have finally been able to confirm that the baffling ‘fast radio bursts’, which are about 1 billion times brighter than anything in our galaxy, have their origin in outer space.
The mysterious phenomena were first noticed in 2007 when the ‘Lorimer burst’ was discovered in archived data from 2001. Since then, more than a dozen fast radio bursts (FRBs) have been detected in telescope data.
The blasts last for just a few milliseconds, occurring as one-off events with just a single burst recorded from a single location. They can emit as much power as 500 million suns.
