NASA image: Good night from space
× close
Earth's thin atmosphere stands out against the blackness of space in this photo shared on Aug. 31, 2015, by NASA astronaut Scott Kelly on board the International Space Station.
The station's solar panels can be seen in darkness at the right of the image.
Kelly, in the midst of a year-long stay on the orbital outpost, shared the photo in a tweet: "Day 157. At the end of the day, #sunrise will come again. Good night from @space_station! #YearInSpace."
