Scientists Puzzled When Mars Rover Finds Egg-Like Rock

Who said there's an egg crisis? NASA's Perseverance Rover has stumbled across an extremely strange rock that's "astonished" scientists while exploring the rim of the Jezero crater on Mars. Nicknamed "St. Pauls Bay," the rock is made up of hundreds of densely packed, millimeter-sized dark spheres — not unlike an insect's slimy egg cluster. These "spherules," as they're known, are somewhat heterogeneous. As seen in a closeup taken with Perseverance's SuperCam Remote Micro Imager, some of them appear more elliptical while others are more angular. Stranger still, some spherules have tiny pinholes through their centers. In short, they're nothing like the rocks that make up the surrounding landscape, which are lighter and flatter. I'm finding bumpy rocks on this side of Mars, too! While different than yours, these spheres are created when droplets of molten rock are thrown into the air by volcanoes or meteorite impacts. The droplets cool as they travel, forming round shapes. https://t.c ... Read full article.
