Here’s a joke for astronomy buffs: what’s a black hole’s favorite meal? Spaghettification! Of course, the joke only makes sense if you know what spaghettification means. This A Moment of Science explains that punchline.

Today's Moment of Science is about a galaxy called UGC 1382. For a long time, scientists thought it was a fairly small, run-of-the mill galaxy, but then they realized it actually had huge spiral arms.

It might sound odd, but scientists think Mars is going to have a ring around it in tens of millions of years. They're predicting that one of Mars' moons, Phobos, is going to break apart, and its particles are going to make a ring around Mars.
