Fastest wind observed around black hole

Scientists recently clocked the fastest ever observed wind blowing off the disk around a stellar-mass black hole, according to media report on Tuesday. Using NASA's Chandra X-ray Observatory, scientists spotted the particle wind, which was calculated moving at a record-breaking speed of 32 million kilometer per hour, or about 3 percent the speed of light. The black hole, known as IGR J17091, was found in the central Milky Way galaxy, about 28,000 light-years from the Earth. "It's a surprise this small black hole is able to muster the wind speeds we typically only see in the giant black holes. It's performing well above its weight class." said co-author Jon Miller, from the University of Michigan. Scientists suggested that the strong magnetic fields around the black holes may be responsible for such a high speed. The observation has important implications for better understanding how this type of black hole behaves, scientists said.
