These massive objects can famously swallow everything—even light—that could proffer obvious signs of their presence. Scientists seeking them out must rely on more circumstantial evidence, which comes from the fact black holes are messy eaters: As material funnels into one, it piles up into a spinning disk of glowing debris that can spit out x-rays and enormous jets of subatomic particles. Astronomers have long considered these energetic jets to be a feeding black hole’s calling card—but new observations of similar phenomena from an exotic type of star suggest identifying black holes is about to get even harder.
