We see clouds so often that it’s easy to forget how amazing they are. Thankfully German astronaut and geophysicist Alexander Gerst is currently aboard the International Space Station where he often spends his free time taking countless extraordinary photos of the Earth as it’s whizzing by 205 miles below.
Gerst is particularly fond of photographing dramatic shadows cast by cloud formations - something that we cannot see down here on Earth. These stunning photos remind how awesome clouds are as they cast shadows that stretch for thousands of miles across the planet’s surface. Shadows so long that they eventually disappear into the black horizon.
