A new study confirms that Earth's inner core has been rotating more slowly than usual since 2010. This mysterious "backtracking" could also end up slightly altering the planet's overall rotation, lengthening our days.

In July 1054, astronomers in China documented a "guest star" in the sky that shone as brightly as Jupiter for nearly a month before gradually fading into invisibility. That "star" was, in fact, a cloud of debris blown into space by a dying star roughly 6,500 light-years away in the constellation Taurus. In the 19th century, Irish astronomer Lord Rosse named the curious object the Crab Nebula, not least because it appeared to have "streams running out like claw
