在遙遠的火星上，NASA的Perseverance Rover發現了一些有趣的白色斑點，這些斑點就像流行的地球上的花豹一樣，圍繞著黑色邊框。這些斑點被稱為‘花豹斑點’，它們的大小只有幾毫米，出現在一塊名為Cheyava Falls的岩石上。科學家們正在研究這些斑點，猜測它們可能是古代火星生命留下的痕跡。這些斑點讓科學家們感到興奮，但目前還沒有證據可以證明它們是生物產物。也有可能是其他非生物的原因導致了這些變化。無論如何，研究這些奇特的斑點是非常有趣的！
原文:
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.
