NASA's Chandra X-ray Observatory has recorded ultra-fast 20 million-mph (32 million km/h) winds roaring from a gas disk around the stellar-mass black hole IGR J17091-3624. The wind speeds are a record, a factor of ten greater than any previously recorded, for a black hole of this kind. It is hoped the surprise discovery will shed new light on the behavior of stellar-mass black holes.
A black hole discovered by NASA's Chandra X-ray Observatory is generating winds blowing at 20 million miles per hour - about three percent of the speed of light. read more Read Post
Astronomers using NASA's Chandra X-ray Observatory have clocked the fastest wind yet discovered blowing off a disk around a stellar-mass black hole. This result has important implications for understanding how this type of black hol... Read Post
