Back from the dead, a black hole is erupting after a 100-million-year hiatus

Inside an incredibly bright cluster of galaxies, a long-dormant supermassive black hole has come back to life. Radio images captured a one-million-light-year-long stream of star-forming particles and gas emanating from the black hole at the center of the galaxy J1007+3540—which apparently is erupting for the first time in about 100 million years.
“Although some ‘restarted’ radio galaxies are known in the literature, J1007+3540 stands out,” says lead study author Shobha ***** ari of Midnapore City College in India.
