Back in the year 1054, Chinese astronomers spotted what looked like a new star, which soon dimmed. They’d actually seen a supernova: a star exploding, ejecting gas and dust and perhaps collapsing. Today, all that’s left of the supernova is a cloud inside the constellation Taurus with a central, rapidly spinning neutron star called a pulsar. Pulsars are extreme objects that have about the mass of our sun but are mere kilometers across. They typically rotate at a constant rate and emit a beam of radiation that appears to us like the regular flashing of a lighthouse. Recently, that pulsar hiccuped.
