Bizarre piles of rock have formed on Mars and NASA isn't quite sure what caused them

NASA's Mars Reconnaissance Orbiter (MRO) is taking pictures of the Red Planet and a newly released photo has revealed bizarre piles of rock.

The photo, released by NASA and taken on Jan. 27, shows boulders set at regular intervals within the stripes of light, on top of the flat ground below. NASA has theorized that it may be a sign of the phenomenon known as "frost heave," but did not specifically say that is what is causing the occurrence.

"With frost heave, repeatedly freezing and thawing of the ground can bring rocks to the surface and organize them into piles, stripes, or even circles," NASA officials wrote in a description of the photo. "On Earth, one of these temperature cycles takes a year, but on Mars it might be connected to changes in the planet's orbit around the Sun that take much longer."
