A supermassive black hole is blasting out X-rays about every nine hours, according to data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton, as described in our latest press release. This indicates that this black hole, containing about 400,000 times the mass of our Sun, is consuming significant amounts of material about three times per day.
The main panel of this graphic is a visible light image taken by the Digitized Sky Survey (DSS) around the galaxy known as GSN 069, located in the center of the image. The inset gives a time-lapse of Chandra data taken over a period of about 20 hours on February 14 and 15, 2019, centered on the X-ray source in the middle of GSN 069. The sequence runs in a loop to show that the X-ray brightness of the source changes regularly and dramatically over the Chandra observation. Three X-ray eruptions are observed. (Note that to clearly show the Chandra source is located in GSN 069, the size of the box in the center of the DSS image is about ten times larger than the Chandra field in the inset.)
XMM-Newton was the first to observe this phenomenon in GSN 069 with the detection of two bursts on December 24, 2018. Researchers then followed up with more XMM-Newton observations on January 16 and 17, 2019, and found five outbursts. The Chandra observations less than a month later — on February 14 and 15 — revealed an additional three outbursts.
These repetitive outbursts are evidence that the supermassive black hole at the center of GSN 069, located 250 million light years from Earth, is consuming about four Moons' worth of material about three times a day. That's equivalent to almost a million billion billion pounds going into the black hole per feeding. ...
