NASA launched the Hubble Space Telescope on April 24th, 1990. Since then we’ve discovered things that we never even imagined, and seen light from distant galaxies and stars billions of years old.

Named for groundbreaking astronomer Edwin Hubble, the Hubble Space Telescope has helped astronomers prove the existence of black holes, dark energy, and defined the age of the universe.

NASA celebrates 20 years of amazing astronomical discoveries with the Hubble Space Telescope with an interactive showcase of incredible images of our universe.

NASA has also announced the extension of the Hubble Space Telescope Science Operations Contract through April 2013, which will extend science operations with the Association of Universities for Research in Astronomy for the Hubble Space Telescope Science Operations Center located at the Space Telescope Science Institute in Baltimore.
