Scientists just detected another repeating radio signal in deep space

Scientists Find 13 Mysterious Deep Space Flashes Including 2nd Known'Repeater

"And with more repeaters and more sources available for study, we may be able to understand these cosmic puzzles-where they're from and what causes them", said Ingrid Stairs, a researcher at the university, in the news release. A repeating FRB, however, provides more opportunities for scientists to learn about these radio bursts and where they come from. The first repeating fast radio burst was recorded at a frequency of 700 megahertz, but some of the bursts CHIME recorded were as low as 400 megahertz.

"FRBs, it seems, are likely generated in dense, turbulent regions of host galaxies", Shriharsh Tendulkar, a corresponding author for both studies and an astronomer at McGill University in Canada, told AFP news agency.

The CHIME/FRB Collaboration includes scientists from UBC and McGill as well as the University of Toronto, the Perimeter Institute for Theoretical Physics and the National Research Council of Canada.

"Different emission mechanisms expect that FRBs will be emitted within a certain range of radio frequencies, much like a light bulb can not emit X-rays or a microwave oven can not emit ultraviolet light", Tendulkar told Gizmodo.

The presence of a second source of repeat FRBs - as well as the detection during CHIME's brief active pre-commission period - hints at the potential existence of two different types of radio bursts, one that happen only once and another that results in multiple bursts from one spot. Whatever the photons pass through, that interaction is recorded in the radio waves and can be "translated" after it's received by the telescope.

However, Tendulkar said it was extremely unlikely the waves were caused by intelligent life. These effects vary with frequency, and many of them become stronger at lower frequencies.

Having two sets of repeating bursts could also allow scientists to understand what distinguishes them from single bursts, helping them understand more about their source and watch for future blasts. Dozens of mysterious radio signals have been noted by scientists with telescopes being used all over the world to track its source.

Mysterious radio signals (artist's impression) have reached Earth - from a galaxy 1.5 billion light years away. Whatever they are, CHIME's initial detections suggest that the $13 million radio telescope will be a powerful tool for tracking down more of the bursts.

Good said that "if we had 1,000 examples, we would be able to say many more things about what FRBs are like".

The CHIME observatory, in British Columbia's Okanagan Valley, has four 100-metre-long, semi-cylindrical antennas, which scan the entire northern sky each day.

The new repeating FRB has another unusual characteristic as well. While interesting, these new observations, he said, can not tell us about the nature of these sources-at least not yet. "But it has to be in some special place to give us all the scattering that we see". If observers could find 13 such bursts this early into CHIME's lifespan, there's a real possibility that it will find others.
