A Decade of Discovery
All About Hubble

GalileoNearly 400 years ago, the Italian scientist Galileo opened a whole new world when he pointed the newly invented telescope toward the heavens. His crude telescope detected pockmarks on the moon and satellites around Jupiter, proving that the Earth wasn't the only special place in the cosmos. Galileo's discoveries revolutionized our view of our place in the universe.

Launch The launch and deployment of NASA's Hubble Space Telescope, likewise, has changed our understanding of the heavens. From capturing the nearby, violent death of a massive star to staring far back in time to see embryonic galaxies, Hubble's many awe-inspiring moments have brought the beauty and mystery of space to homes all over the world.

Hubble in OrbitThe Earth-orbiting observatory collects and analyzes light from visible to near infrared, seeing more sharply than any previous telescope. The telescope has a much clearer view of the heavens because of its unique position above Earth's roily atmosphere, which distorts starlight, making it dance and wiggle. Its razor-sharp vision of celestial objects has turned the "hints and suspicions" of terrestrial observations into certainties, forcing theorists to rewrite broad-brush theories.

By observing 14,000 astronomical targets, Hubble has contributed significantly to astronomical research, from our solar system to the most distant galaxies.
