Hubble Telescope Screen Saver displays a collection of color photographs taken from NASA's Hubble Space Telescope.

The screen saver displays 37 images as a slideshow. There are options that let you choose the time delay between images (in seconds or minutes), select which transition effects to use, and stretch the images to fit the screen or display them in their original size.

This screen saver also supports Microsoft Plus!. This lets you select 'hot corners' on your screen to automatically display the screen saver, or prevent it from appearing.

It also comes complete with a 'Screen Saver Control' utility that lets you select, configure, and launch any installed screen saver with a click to the System Tray icon.
