Black hole space volcano erupts after 100 million year nap

Spanning 1 million light-years, J1007+3540's plasma jets are nearly 10 times wider than the Milky Way. Breakthroughs, discoveries, and DIY tips sent six days a week. A supermassive black hole is reawakening inside a distant galaxy cluster--and after almost 100 million years of slumber, astronomers now say it's making up for lost time. According to a study published today in, J1007+3540 is erupting like a volcano and spewing plasma across interstellar space. In fact, it can lay dormant for eons.
