In Arp 220, a galaxy 250 million light-years from Earth,
NatGeo said:astronomers have spotted a record-breaking seven supernovae all found at the same time.
"As far as we know, only three supernovae in a single galaxy were found at once so far, which is already an impressive number," said study leader Fabien Batejat, a Ph.D. student at Chalmers University of Technology in Onsala, Sweden.
