Leopard Spots on Martian Rocks
Explanation: What is creating these unusual spots? Light-colored spots on
Martian rocks, each surrounded by a dark border, were discovered earlier this month 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 ring, like some
similarly appearing spots on
Earth rocks. Although other
non-biological explanations may ultimately prevail, speculation focusing on this potential biological origin is causing
much intrigue.
