This is a very interesting video that talks a little about the Hubble Space Telescop, and what it was able to see of other galaxies while in orbit. It gives a good perspective on how small our planet is compared to the rest of the Universe.
More from the huble space telescope, this video shows a series of pictures taken by it, including some galaxies, forming stars, and other planets. It also tells a little about the telescope itself and how it was launched.
