NASA’s Swift Studies Gas-Churning Monster Black Holes

https://science.nasa.gov/missions/swift/nasas-swift-studies-gas-churning-monster-black-holes/?utm_source=newsletter&utm_medium=email&utm_campaign=nn50 Scientists using observations from NASA’s Neil Gehrels Swift Observatory have discovered, for the first time, the signal from a pair of monster black holes disrupting a cloud of gas in the center of a galaxy. The dual black holes are in the center of a galaxy 1 billion light-years away in the northern constellation Cygnus. The pair are about 16 billion miles apart, close enough that light only takes a day to travel between them. Together, they contain 40 million times the Sun’s mass. Scientists estimate the black holes complete an orbit every 130 days and will collide and merge in approximately 70,000 years.
