The Mars Reconnaissance Orbiter has taken incredible images of another giant dust devil, similar to one photographed in February, but much larger. This one, in Amazonis Planitia, is about 20 kilometres (12 miles) tall! That’s also a lot bigger than typical dust devils on Earth, more like the size of a terrestrial tornado.

There are also two animations, here and here.
