Astronomers using XRISM have found that winds from a supermassive black hole are about 100 times more powerful than previously thought. The finding is based on turbulence produced by these winds, which was measured spreading roughly 300,000 light-years from the black hole.
That distance places the effect far beyond the black hole's host galaxy, suggesting the winds can influence a much larger volume of space than expected. Because only one source was available, there are no conflicting measurements to compare, but the reported result marks a major shift in how powerful such black hole winds can be.
