SpaceFap – This NASA Time Lapse Video is Beautiful

Space, it’s something I think a lot of us can relate to that most of us just want to go out there one time and look down on Earth. NASA instead took this video a little different route. It’s crazy to see everything from the perspective of a fixed point on the stars and the EARTH actually moving, because that’s how it really is. The stars don’t move, we do.

Here is an explanation of the video from NASA:

Why is the Earth moving in the above video? Most time lapse videos of the night sky show the stars and sky moving above a steady Earth. Here, however, the frames have been digitally rotated so that it is the stars that stay (approximately) steady, and the Earth that moves beneath them. The video dramatically shows the actual rotation of the Earth, called diurnal motion, in a clear and moving way, as if the camera were floating free in space. The telescopes featured in the video are the Very Large Telescopes (VLT) in Chile, a group of four of the largest optical telescopes deployed anywhere in the world. A discerning observer of the above time lapse movie may also note the use of laser guide stars, zodiacal light, the Large and Small Magellanic Clouds, and fast-moving, sunlight-reflecting, Earth-orbiting satellites. The original video, on which the above sequences are based, can be found here.
