Balancing Rock on Comet彗星上的悬石

Dean

A probe探测器 orbiting a comet彗星 speeding through deep space may have spied捕捉到 something a little odd奇怪: a huge, balancing rock悬岩 on the comet's surface.
The European Space Agency's Rosetta 「罗塞塔」号spacecraft航天器 snapped拍摄 a photo of a boulder巨石 that appears to be balancing on Comet 67P. The large boulder is about 98 feet in diameter, a little longer than an NBA basketball court篮球场.
The balancing rock is joined by two other rocks that also cast投射 shadows阴影 on the comet's surface.
Scientists working with Rosetta hope to learn more about the balancing rock formation形成 as the probe continues to monitor监视 the comet during its trip around the sun. The comet will make its closest approach靠近 with the sun in August.
