A windy day on HD 189733b is nothing to take lightly.
A solar storm that missed Earth but smashed into Mars last March dramatically confirmed long-held suspicions that the sun is blasting away the Martian atmosphere, and doing so at a rate that will leave the planet airless in another couple of billion years, if not sooner.

In 'The Martian,' astronaut Mark Watney gets hit by debris, blown away and partially buried by a terrible Martian dust storm. But how accurate is this depiction of living on the Red Planet?
New photos from NASA's mission to Pluto reveal more detail in the dwarf planet's dynamic atmosphere and surprising landscape.
