X-rays show galactic black hole spinning near speed of light

Black hole

Black holes may have given up some secrets of their growth thanks to the sleuthing of two X-ray space telescopes. The findings have solved a long-standing mystery about a supermassive black hole’s spin, finding that some of them can whirl very close to what the speed of light allows. NASA’s X-ray telescope NuSTAR teamed up with the European Space Agency’s XMM-Newton space ... Read More »

Scientists discover black holes weighing 40 billion suns

Arp 147

This NASA image shows a new image of a ring – not of jewels – but of black holes. This composite image of Arp 147, a pair of interacting galaxies located about 430 million light years from Earth, shows X-rays from the NASA’s Chandra X-ray Observatory (pink) and optical data from the Hubble Space Telescope (red, green, blue) produced by ...

Astronomers discover a new black hole in our galaxy

Xray nova flaring black hole

This is the X-ray nova flaring black hole. NASA’s Swift satellite recently detected a rising tide of high-energy X-rays from a source toward the center of our Milky Way galaxy. The outburst, produced by a rare X-ray nova, announced the presence of a previously unknown stellar-mass black hole. “Bright X-ray novae are so rare that they’re essentially once-a-mission events and ...
