The Telescope Science Institute provides a web site for the Hubble Space Telescope through http://HubbleSite.org/. The telescope is named for Edwin P. Hubble an astronomer who proved the existence of other galaxies and determined the relationship between the distance of galaxies and the speed at which they are moving.  The telescope was launched into orbit in 1990 with the simple mission of capturing detailed images of space. The results have been simply astounding. Throught the site, you can download free images captured from the telescope for use as desktop wallpaper or printed art.  The site also features a children’s section and resources for teachers.  Even those with casual interest in space exploration will be amazed with the images.
