This is an article from the RT website.
An unknown radio signal, which may have come from a black hole, colliding neutron stars (or – for those who ‘believe’ – alien life), has been picked up by astronomers live for the first time ever. Its origins remain mysterious.
The fast radio bursts are quick, bright flashes of radio waves that last only milliseconds, but still emit as much energy as the sun in an entire day.
This is the first time that these radio waves have been spotted live. The first burst was picked up in 2007 by sifting through old data at the Parkes Radio Telescope in Eastern Australia. Only seven others have been seen since then.
This time, the mysterious waves were picked with the use of 12 telescopes in Australia, Chile, Germany, Hawaii, India, California and the Canary Islands.
Because they observed the radio waves in real time, they were also able to try and find other wavelengths, like x-rays or infrared to find out their source...but remained unable to find anything.
“The fact that we did not see light in other wavelengths eliminates a number of astronomical phenomena that are associated with violent events such as gamma-ray bursts from exploding stars and supernovae, which were otherwise candidates for the burst,” Daniele Malesani, of the University of Copenhagen, told Astronomy Magazine.

Ok. can anyone simplify this for us please?
