Astronomers have discovered an object that orbits dangerously close to its parent white dwarf star. It should have been crushed to death by the dying star’s gravitational pull, but has miraculously stayed intact somehow.

“The planetesimal we have discovered is deep into the gravitational well of the white dwarf, much closer to it than we would expect to find anything still alive,” said Boris Gaensicke, co-author of the research published in Science and a physics professor at the University of Warwick.
