A Shadow of Phobos

I saw this very cool animation of the shadow of Mars‘ moon Phobos passing over a dust storm. Apparently an enterprising enthusiast combed through online archives of photos taken by the Viking 1 probe back in ’76 and found this sequence. It’s kind of cool to see that people are still finding new information this much later. If you’re an astronomy nerd like I am you’ll probably find it worth checking out!
