Astronaut Reid Wiseman posted a Vine over the weekend from the International Space Station (ISS) for the first time in history. The beautiful, six-second video is a condensed time-lapse capturing the ISS's 92-minute orbit around Earth:
The cool details: While the idea of a space Vine is mind-boggling on its own, Wiseman's video is especially awesome because it captures something most of us will never have the chance to see from afar: the terminator line.
The so-called "twilight zone" is a moving line that separates the light and dark sides of a planet. As Wiseman points out, the orbit of the ISS is almost parallel to the terminator line, which means that astronauts aboard are currently experiencing daylight all day long.
A whole new world: As if his Vine wasn't cool enough, Wiseman has also been regularly posting these stunning photographs of Earth from the ISS. This is serious social media game right here:
