Towering cloud on Mars is a mystery

Cosmic Log – Mysterious cloud spotted on Mars.

Amateur astronomers are puzzling over a seemingly anomalous cloud that has shown up on images of Mars taken over the past few days. Is it really a cloud, or a trick of the eye? Does it really extend 150 miles up from the surface, as some of the observers suggest? And what churned up all that stuff, anyway? The amateurs and the pros will be trying to resolve those questions before the phenomenon fades away.

“It’s not completely unexpected,” Jonathon Hill, a member of the team at the Mars Space Flight Facility at Arizona State University, told me today. “But it’s bigger than we would expect, and it’s definitely something that our atmosphere guys want to take a look at.”

The thing is still there. Fading away though. It was discovered by an amateur, Wayne Jaeschke, on March 20. This goes to show that amateur astronomers can provide valuable information. But, the good thing is, it was passed to the experts who are the only ones who have the tools to potentially figure it out.
