(CNN NEWSOURCE) NASA's Mars Exploration Rover Opportunity caught a unique weather picture on mars.

It’s an image of what NASA calls a Martian dust devil.

You can see it twisting through the valley.

Dust devils on Mars are created like those on Earth. A column of hot air begins to rise and rotate, picking up tiny grains of dust from the ground, and making the spinning vortex visible.
