For nearly a decade, or as NASA says, 3508 sols, the space agency's Curiosity rover has been exploring Mars. During that time, Curiosity and its fellow rover, Perseverance, have spotted all sorts of things on the Red Planet. While they've observed plenty of rocks and dust, they've also encountered some stranger items, like an "alien boot," metallic wreckage, a flying UFO, a mysterious doorway, and what looks like an alien. Now, Curiosity has sent back some of its weirdest pictures yet, and the photos seem to show alien arms reaching out of the ground.
NASA shared the pics, explaining that the strange rocks "likely formed as groundwater trickled through rock in the ancient past, depositing mineral cements over time; many years later, when the rock was exposed to the atmosphere, wind eroded the softer material around the cemented portions."
However, conspiracy theorists think otherwise. One wrote, "That is not the case here. What we see are two metal arms sticking out of an actual alien under that rock. I believe if you lift up this huge rock, you will find the remainder of the creature. I think something threw this huge rock on purpose to kill the alien creature attacking it. This creature has an exoskeleton...an outer skeleton like an insect would have. Thus, this is an intelligent insect species that was attacking and was killed here."
The rocks are located on Mount Sharp, a three-mile-tall mountain that Curiosity has spent the last 8 years climbing.
Whether you believe that the rocks are just odd formations or that they are arms belonging to aliens, you can see more of what Curiosity is finding by following the rover on Twitter.
