Earth At Night Video
Perhaps you’ve already seen all the impressive Earth at night images (like this famous one), but here something new: an actual video of Earth rotating, as taken from the night side. This is really impressive, and you must watch it at full screen in full HD resolution (and, if you have 3D glasses handy, there’s a 3D mode available if you view it directly on YouTube).
The video was taken over 22 nights by Soumi NPP Earth-observing satellite. If you want to read more about, check out what Phil Plait has to say.
