NASA astronaut Christian Koch snapped this image of Hurricane Dorian from the International Space Station yesterday, from more than 200 miles (300 km) above Earth. Dorian was at a near-standstill over the Bahamas for most of the day yesterday, where it caused at least 5 deaths and destroyed thousands of homes.
