German astronaut Alexander Gerst with the European Space Agency created a photo-animation of Earth using over 12,500 images gathered by the International Space Station. The his video offers some stunning views of the Earth as the ISS passes over the planet. There is some pretty "spacey" music to accompany the animation as well.

For more detailed science results, an ESA manager working with the Hubble Space Telescope team walks through answers to some questions submitted about Hubble discoveries made by the telescope as it peered at distant galaxies. The background music is more subtle. WHB
