This from the New York Times web site, specifically, the slide show which is a huge time-vampire.
Moving ice too on Mars? Examining images like this one of a canyon taken by Mars Reconnaissance Orbiter, scientists at Brown University believe they see evidence of flowing glaciers on Mars within the last 10 million to 100 million years. That counts as very recently on a geological timescale and runs counter to the prevailing view that Mars’ climate has been largely quiet for the past 3.5 billion years. The Brown researchers believe rock debris seen in the image was left by a glacier that rose at least half a mile from the surrounding plain and flowed onto the canyon.
Brown researchers made the cover of the May issue of Geology with this work.
