Canada’s Radio Telescope Picks Up Strange New Signal

Canada’s new radio telescope has picked up a mysterious signal from deep space with a frequency so low, it’s never been detected before. The Canadian Hydrogen Intensity Mapping Experiment (CHIME) detected the ‘fast radio burst’ July 25.

FRBs frequently are picked up on radio telescopes, though their exact origins aren’t fully understood. This most recent one, named FRB 180725A, is notable because of its low frequency of 580 megahertz. Before this, there had never been an FRB picked up below 700 MHz.

It’s likely that FRBs come from turbulent black hole activity, such as when two black holes merge into one. CHIME is located in British Columbia and its FRB from last month was reported in a post by the Astronomer’s Telegram.

One FRB, FRB 121102, has been detected several times before — and researchers believe its origin is in a galaxy some 3 billion light years from Earth, meaning it would have to be extremely powerful to be picked up on a telescope. Source: News.Com.Au
