Finger-like rock structures on Mars could harbor potential evidence of past life on the Red Planet, according to new research. In 2007, NASA’s Spirit rover landed on Mars’ “Home Plate,” a flat 90-meter-long area within the Gusev crater. Since then, researchers have been trying to make sense of finger-like rock structures splayed across the landscape. The working hypothesis at the time was that these rocks started out as continuous layers but eroded into odd shapes by the touch of wind and sand over the years.
