Explanation: What is creating these unusual spots? Light-colored spots on Martian rocks, each surrounded by a dark border, were discovered last year by NASA's Perseverance Rover currently exploring Mars. Dubbed leopard spots because of their seemingly similarity to markings on famous Earth-bound predators, these curious patterns are being studied with the possibility they were created by ancient Martian life. The pictured spots measure only millimeters across and were discovered on a larger rock named Cheyava Falls. The exciting but unproven speculation is that long ago, microbes generated energy with chemical reactions that turned rock from red to white while leaving a dark biosignature ring, like some similarly appearing spots on Earth rocks. Although other non-biological explanations have not been ruled out, speculation focusing on this potential biological origin is causing much intrigue.

That’s rust - don’t they know rust never sleeps??
Fascinating. Are these like Martian fossils?
Wow.
Cool.
copper?
My guess is itâs the migration of elements during the solidification process much like a eutectic forms in the iron/carbon alloy.
“Dubbed leopard spots because of their seemingly similarity to markings on famous Earth-bound predators,”
Proof the leopards beat us to Mars. They’re not as Earth bound as we thought.
Look for several democRATS to ask just how the leopards managed to travel to Mars. Also, did any of the leopards plant the American flag on Mars?
The leaping ability of leopards is underestimated. You should notice that they are not finding donkey dung.
The heartbreak of psoriasis?
Some Windex will clean that right up. Next rover needs a scrub brush attachment.
It looks like mold to me. That would be incredible if it was.

Sorry. I donât know what happened. Blame it on the MartiansâŠ.
