Two dead, dancing stars challenge astronomers' expectations
Stars still have plenty of surprises despite (or perhaps, because of) advances in astronomy. Researchers using Caltech's Zwicky Transient Facility have discovered a binary white dwarf system 8,000 light-years away, ZTF J1539+5027, where the two dead stars orbit each other every seven minutes. That's the second-fastest pair of white dwarfs seen to date, and the fastest such "eclipsing" system (where one passes between its partner and Earth). This isn't the first time they've seen one white dwarf 'eat' the other, but it's rare to catch this cannibalization in the act.
