Mysterious fast radio bursts from deep space ‘could be aliens’
Astronomers have detected mysterious, ultra-brief repeating energy bursts from deep space for only the second time in history, and some experts suggested they could be evidence of advanced alien life.
The origin of fast radio bursts (FRBs), millisecond-long pulses of radio waves, is unknown, but most scientists say they are generated by powerful astrophysical phenomena emanating from billions of light years outside our galaxy, the Milky Way – such as black holes or super-dense neutron stars merging together. Some, however, including Prof Avi Loeb, from the Harvard-Smithsonian centre for astrophysics, have posited more outlandish theories, suggesting they could be evidence of incredibly advanced alien technology.
The new discovery, made by a Canadian-led team of astronomers searching for FRBs, was published in the journal Nature following a three-week period last summer during which the group detected 13 of the flashes using a new type of radio telescope, the Canadian Hydrogen Intensity Mapping Experiment (Chime), in British Columbia’s Okanagan Valley.
