No, that’s not what the Predator sees when he looks out the fisheye lens on his apartment door. It’s in fact a picture of methane on Mars, no doubt through a camera that makes it more colorful–it’s not like methane turned the red planet blue.
And chances are if you frequent this site you’re thinking right now, “That means Mars is a lot like Bartertown!” E-xactly. This was detected by NASA, who said this indicates “the planet is either biologically or geologically active.”
This from the lasted round-up of nifty space photos from NASA, which includes Venusian arachnoids–and no, Dindrane, they’re not giant alien spiders, they’re “volcanic centers surrounded by networks of cracks.” So take deep breaths. Also there’s a computer simulated pic of HD 80606b, an extrasolar planet. Go and enjoy.
