And the more we explore our near planetary neighbor, the weirder the things we find get. NASA’s Mars Reconnaissance Orbiter, which has been circling Mars since 2006, provides the clearest and highest-resolution images of the planet’s surface. Looking through the image archive of its HiRISE camera, which can resolve things about a meter wide on the ground, reveals a vast supply of strange and wonderful things.

Here we share some of the orbiter’s most recent weird sightings from the last few months. The images provide incredible scientific insights into Mars. But, perhaps just as important, they are beautiful, fascinating, and reflective of the alien world that sits not too far from our own.
