That's no moon. Oh wait. Yes it is. This is a photo of Mars, taken before dawn by our Perseverance rover, and that tiny dot in the sky is Deimos, the smaller of Mars' two moons. Deimos is much, *much* smaller than Earth's Moon: it's about 9 by 7 by 6.8 miles (15x12x11 km) in size. Because it's so tiny, its gravitational forces make it more of a lump than a sphere. Because it was taken at night with a long exposure time, this image of the Martian night sky is a little more grainy than other photos we've received from our Perseverance and Curiosity rovers. Would the night sky on Mars be filled with twinkling stars like we’re used to seeing on Earth? Get the full story from NASAJPL in an Instagram Reel they published on April 15, 2025. Image description: A gray, dimly-lit Martian landscape. Gentle red hilltops in the distance help separate the surface from the sky, in which a dim white light shines just right of center.
