Ever wonder how astronauts get crazy good shots of the Earth? How about at night, while it’s moving? Turns out, they don’t use tripods.

Wait. Say what? Long exposures with a 400mm+ lens without a tripod?

Yup. They can do that. All because of a little thing called gravity. Don’t believe me? Check out the video with Chris Hadfield. You know, the Canadian astronaut that’s also a YouTube sensation? He explains how he does long exposures free hand with a little help from zero gravity.
