While many of you gazed at the total lunar eclipse on Jan. 20, you probably had no idea you were witnessing something unprecedented. Amateur astronomer Christian Fröschlin of the Netherlands peered up at the skies, and along with some others around the world, he caught a quick glimpse of a bright flash on a corner of the reddish-tinted moon.
Why it matters: While scientists have observed meteorite collisions on the moon before, this appears to be a first to be observed during a total lunar eclipse. According to Nadia Drake, reporting for Scientific American, the moon gets hit on a daily basis by what are typically small meteorites. (Unlike Earth, the moon lacks an atmosphere where such rocks can burn up before hitting the ground.)
