Monday, September 24 2018: Green auroras shimmy over Earth in this nighttime view from a window of the International Space Station. Russian cosmonaut Oleg Artemyev tweeted the photo from space yesterday (Sept. 23). Visible in the foreground is one of the two Soyuz spacecraft used to ferry astronauts to and from the space station. To the left of the frame, you can see a tiny bit of daylight peeping over Earth's horizon. — Hanneke Weitering
