Mysterious new repeating fast radio bursts (FRBs) have been picked up coming from space, according to a a new study.
Astronomers do not know what causes the FRBs but 25 were counted during the research carried out by the Canadian Hydrogen Intensity Mapping Experiment (CHIME), working with the University of Toronto.
There are now a total of 50 known repeating FRBs and it has led scientists to believe that there may be more than they had first thought.
