I guess this isn't technically astronomy, but it sure is beautiful.

"The High Definition Earth Viewing (HDEV) experiment aboard the International Space Station (ISS) was activated April 30, 2014. It is mounted on the External Payload Facility of the European Space Agency’s Columbus module. This experiment includes several commercial HD video cameras aimed at the earth which are enclosed in a pressurized and temperature controlled housing. Video from these cameras is transmitted back to earth and also streamed live on this channel.
While the experiment is operational, views will typically sequence though the different cameras. Between camera switches, a color and then black slate will briefly appear. Since the ISS is in darkness during part of each orbit, the images will be dark at those times. During periods of loss of signal with the ground or when HDEV is not operating, a color slate or previously recorded video may be seen."
