Ravioli-shaped moon.

In a stunning set of close-ups, Pan, a diminutive moon of Saturn, looks like a floating ravioli lost in space, or a wrinkled flying saucer.

NASA’s Cassini spacecraft took the photographs Tuesday, passing within 15,268 miles of the moon, which has a diameter of about 20 miles, roughly the size of New York City.

Carolyn C. Porco, a visiting scholar at the University of California, Berkeley, who leads Cassini’s imaging team, was asleep when Cassini’s shots were transmitted to Earth. She first saw an image on Twitter.
