Einstein Probe may have caught a black hole tearing apart a white dwarf for the first time - Science Daily

Can a dying star reveal the location of a black hole that has otherwise gone unnoticed? Turns out, it can. Astronomers have now traced a stellar destruction event to a massive black hole about 3,500 light-years from the center of its host galaxy. This discovery offers a rare look at a so-called wandering black hole and raises a further question: how did it end up so far from home?

The discovery, reported in Science Advances, shows a subduction zone actively breaking into pieces. Subduction zones form where one tectonic plate is forced beneath another and pushed deep into Earth. They are responsible for some of the planet's largest earthquakes, powerful volcanic eruptions, and long-term changes to continents and ocean basins. Until now, however, scientists have had few opportunities to see clearly how one of these enormous systems reaches the end of its life.
