Celebrating Hubble's 20th Anniversary

The Earth-orbiting Hubble Space Telescope sparked a revolution in astronomy when it opened its “eye” on the universe 20 years ago. The telescope’s “hall-of-fame” images and spectacular discoveries of black holes, far-flung galaxies, and gas shrouds around dying, Sun-like stars have forever changed our view of the cosmos.
