Astronomers have spotted a cosmic blast that dwarfs all others.
A gargantuan explosion tore through the heart of a distant galaxy cluster, releasing about five times more energy than the previous record holder, a new study reports.
“In some ways, this blast is similar to how the eruption of Mt. St. Helens in 1980 ripped off the top of the mountain,” study lead author Simona Giacintucci, of the Naval Research Laboratory in Washington, D.C., said in a statement. “A key difference is that you could fit 15 Milky Way galaxies in a row into the crater this eruption punched into the cluster’s hot gas.”
