A cluster of eerily circular holes recently appeared in the clouds above Florida, a stunning new NASA image shows. The rare occurrence, which has previously (and incorrectly) been linked to UFOs, has a surprisingly simple explanation — but it took scientists more than 60 years to figure it out.
NASA's Terra satellite photographed the bizarre voids, known as fallstreak holes or hole-punch clouds, above the Gulf of Mexico off Florida's west coast on Jan. 30. NASA's Earth Observatory revealed the striking image on Feb. 26.
