Experience a Beautiful New View of Earth, as Seen From Space

Earth | Time Lapse View from Space, Fly Over | NASA, ISS from Michael König on Vimeo.

Does your brain need a little afternoon stimulation this Tuesday? Check out this beautiful video.

It was created by stitching together several series of photographs taken by astronauts onboard the International Space Station from August to October. The photos were created about 200 miles up, which is the average orbit height of the ISS.

According to Space.com, the video required very little color correcting or digital editing, so the beautiful view you're seeing is real. Those amazing auroras that permeate the video are triggered by charged particles from the solar wind interacting with Earth's atmosphere. The result is one of the most stunning videos of Earth to hit the web.

Watch NASA's New Robot Come to Life

NASA/Frankie Martin NASA has compiled an amazing series of photos showing the construction of its new humanoid robot, Robonaut 2 (aka R2).       

R2 weighs a whopping 300 pounds and runs on a battery. The robot will join the Discovery shuttle team on their Nov. 1 mission to the International Space Station for a series of operational tests. Eventually, though, R2 will help spacewalking astronauts with tasks outside the space station.
