E.T. could well be phoning home, as scientists have detected 25 mysterious ‘fast radio bursts’ from outer space.
These blasts of powerful radiation were picked up by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope between 2019 and 2021.
It is not currently known what produces fast radio bursts, or FRBs, but they are generally thought to be emanated by dying stars in distant galaxies.
