Radio burst from galaxy far, far away
SCIENTISTS have picked up a rare, mysterious radio signal from the other side of the universe. The low-frequency super-fast burst (FRB) lasted just milliseconds.
But experts say it is the lowest radio emission received from beyond our Milky Way – and its source is therefore likely to be extremely powerful.
Theories suggest the signal, named FRB 180725A, could originate from a black hole – or even an alien civilisation.
FRBs were first discovered in 2007.
Only about 24 have been picked up since.
The latest phenomenon was detected on July 25 by the new £12million Canadian Hydrogen Intensity Mapping Experiment (Chime) telescope in British Columbia.
University of Nottingham astrophysics professor Christopher Conselice said the discovery could help pave the way for a greater understanding of what causes FRBs.
“We don’t know their origin, they could be caused by a number of things,” he said.
“They could be caused by exploding stars, supernova, exotic stars like pulsars, magnetars, neutron stars or massive black holes at the centre of distant galaxies.
“It could even be some other physical mechanism we don’t yet understand.”
