A Martian Solar Eclipse

Mars has two moons, Phobos and Deimos. NASA's Perseverance rover recorded the transit of Phobos across the sun on April 2. Mars rovers have been recording eclipses since 2004, but this is the highest-quality video sent back to earth yet. Phobos is much smaller than our moon, and its orbit is much more eccentric. It's also shaped like a potato. Phobos' orbit is slowly disintegrating, which means it will spiral down to Mars' surface, in a few tens of millions of years. So it's a good thing we have video.
