Via Earth Sky:
"By now, we all know what the Earth looks like from space. But to see our home planet from above – in real time – is truly something special. Is that what you’ll see in the live video feed below? Sometimes. The live video feed below is from the International Space Station (ISS), and it also includes internal views when the crew is on-duty, a map showing the path of ISS in orbit, ISS turning its camera on itself, and other features. The video is accompanied by audio of conversations between the crew and Mission Control. One other caveat. This video feed is available only when ISS is in contact with the ground. During “loss of signal” periods, viewers will see a blue screen. (Sometimes it takes a while to load.)"
