Strange Image on Mars

A self-described "armchair astronaut" claims to have found a base on the planet Mars using a satellite imaging map. He thinks the base could have been made by aliens

The video David Martines uploaded to YouTube has been viewed more than 850,000 times. He says the 750'-by-150' cylinder-like structure that he's zoomed in on using Google Mars looks like it's made for people to inhabit. In the video, Martines say he assumes people live in the cylinder or have lived in it.

He named the shape "Bio Station Alpha." Experts told Space.come that the image was most likely caused by "cosmic energy" interfering with the cameras--not by aliens.

"It looks like a linear streak artifact produced by a cosmic ray," Alfred McEwen, a planetary geologist at the University of Arizona told Space.com. Cosmic rays, which are emitted by the Sun and other stars, don't make it to Earth because of its magnetosphere. "But with space images that are taken outside our magnetosphere, such as those taken by orbiting telescopes, it's very common to see these cosmic ray hits. You see them on optical images and a lot of the infrared images too."
