NASA's Mars rover Perseverance has uncovered rocks in a dry river channel that may hold potential signs of ancient microscopic life, according to scientists.

Washington

NASA's Perseverance rover has identified a rock on Mars that could hold the most compelling evidence of ancient life ever found on the planet. The rock, discovered in an ancient riverbed, displays unusual markings that NASA scientists believe may be biosignatures of Martian microbes from more than three billion years ago.

NASA officials, including acting administrator Sean Duffy and head of science Dr. Nikki Fox, have highlighted the significance of this find, noting that it stands out from surrounding rocks and represents the most interesting observation in the ongoing search for extraterrestrial life. The discovery brings renewed attention to the question of whether life ever existed beyond Earth.

Rocks found on Mars may hold potential signs of ancient life

Long before astronomer Galileo Galilei first gazed at Mars through a telescope, our neighboring red planet had captured our imagination. Humans have long wondered whether there is or was life on the fourth rock from the sun. As Mark Strassman reports, a rock star named Perseverance may have finally dug up the answer. This is a selfie of Perseverance, the rover that found this rock, potentially the most meaningful rock on Mars NASA has ever studied. Sean Duffy is NASA's acting administrator. This very well could be the clearest sign of life that we've ever found on Mars, which is incredibly exciting. These spots on the rock make NASA giddy, a potential biosignature of Martian microbes in an ancient riverbed more than three billion years old. What made it stand out? It just didn't look like the rocks around it. Dr. Nikki Fox is NASA's head of science. This is by far the most interesting observation that we have made as we continue to look for life elsewhere in the solar system. It's a rock for the ages. And for the big question, are we alone?
