The European Homepage For The NASA/ESA Hubble Space Telescope
I just stumbled upon the official website of the Hubble Space Telescope, spacetelescope.org. spacetelescope.org is a great site, the place to go for all those amazing images, that keeps coming, after Hubble has been in service for 15 years.
The latest published image, is of the Crab nebula, and it is simply outstanding. The Crab Nebula is the remnants of the first historically documented super-nova, that was observed by Chinese astronomers in 1054.
