Scientists, using NASA’s Neil Gehrels Swift Observatory, have identified a black hole in a distant galaxy that appears to be recurrently consuming parts of a Sun-like star. This groundbreaking discovery was made possible by a new method of analyzing data from the observatory's X-ray Telescope (XRT).

It lit up in a galaxy around 500 million light-years away in the northern constellation Triangulum.
“We searched and searched for the event brightening in the data collected by Swift’s Ultraviolet/Optical Telescope,” said Alice Breeveld, a research fellow at the University College London’s Mullard Space Science Laboratory who has worked on the instrument since before the satellite launched. “But there wasn’t any sign of it. The galaxy’s variability was entirely in X-rays. That helped rule out some other potential causes.
