For those who don’t read the Bad Astronomy blog, I feel duty bound to share an image taken by the HiRISE camera currently orbiting Mars. They caught a picture of several avalanches on steep cliffs on Mars:
It’s also worth looking at the full set of pictures, which shows the wide-angle shots and the zoomed-in shots of two avalanches, giving a better sense of how far the orbiter was when the pictures were taken. Modern technology is quite amazing, isn’t it? (I may have found my newest desktop background.)
