Amateur astronomers have spotted huge cloudlike plumes erupting from Mars – a phenomenon that scientists are at a loss to explain...
The researchers initially were skeptical, but "we came to the conclusion that what we were seeing is actually real," says study co-author Antonio García Muñoz, a planetary scientist at the European Space Agency. The plumes are "exceptional. … It's difficult to come to terms with this."
This scientific brainteaser first came to light in early 2012, when amateur astronomer Wayne Jaeschke was poring over footage of Mars he had captured at his private observatory. He came across a puzzling image showing the Red Planet with a blob billowing off the planet's rounded edge.
In all his years of peering at Mars, "I'd never seen anything like that," says Jaeschke, a West Chester, Pa., resident who spends about 100 nights a year training his gear on the heavens. He quietly ran the image by a few friends, then circulated it among a larger group of both amateur and professional astronomers.
