Astronomers could be close to picking up one of the largest space mysteries after a Canadian telescope discovered eight new repeated radio signals known as "fast" radio deficits ""

Rapid radio deficits are light pulses of radio emissions, only milliseconds in duration, believed to come from distant galaxies.

The source of these emissions is still unclear – but researchers have been particularly fascinated by "repeaters", where pulse repeats , ever since the first rapid radio shortage was found in 2007.

Theories range from highly magnetized neutron stars blasted by gas streams from a nearby supermassive black hole, to signatures of technology developed by advanced civilization.

Telescopes have now discovered many more "repeaters", and scientists hope to trace the origins of the mysterious blasts.

Results from the Canadian CHIME telescope were published on the arXiv suppression server, where eight repeaters were detected.

An Australian telescope, the Square Kilometer Array Pathfinder also found one, reported the prestigious scientific journal Nature.

CHIME scientist Bryan Gaensler said: "In 25 years of astronomy research, this is without doubt the most exciting project I have ever worked on,"
