No, this isn't a solar eclipse. It's an image of Mars, captured by NASA's asteroid-bound Psyche probe

Mars as a bright crescent as seen by the Psyche spacecraft as it heads for a Red Planet rendezvous.

Is it an eclipse? An oddly angled crescent moon, perhaps? Nope. This stunning silver arc is actually Mars.

The breathtaking new image of the Red Planet was captured by the NASA spacecraft Psyche as it heads for a close encounter with Earth's planetary neighbor on Friday (May 15).

NASA shared the image captured late on Wednesday (May 13) on its NASA Solar System X feed. The space agency wrote: "This is not an eclipse, but an even more rare sight: a crescent Mars as seen by NASA’s #MissionToPsyche spacecraft. The unprocessed image — taken by Psyche today — shows the night side of Mars as the spacecraft approaches the Red Planet for a flyby on May 15."
