On Sunday, January 20, viewers across the Western Hemisphere were treated to the rusty hues of the decade's last “blood moon” eclipse. But as people across the planet watched the moon glow crimson, some lucky observers caught an unexpected delight: the flash of a space rock striking the lunar orb.
“It's a rare alignment of infrequent events,” says Justin Cowart, a Ph.D. candidate at Stony Brook University in New York. “A [meteoroid] about this size hits the moon about once a week or so,” he says. But if this event is confirmed, it may be the first time such an impact has been recorded during a lunar eclipse.
