Named after astronomer Edwin Hubble, NASA launched the Hubble Space Telescope in 1990. Hubble is a telescope that orbits Earth. Moving air in the atmosphere distorts and bends the light making for twinkling stars and blurrier images. With the Hubble Space Telescope in low-earth orbit about 350 miles above the Earth, it can observe objects deep in space, and objects closer to Earth. The telescope has sent back thousands of images helping scientists shed light on many great mysteries in the universe. Hubble has seen galaxies that were formed near the beginning of the universe almost 14 billion years ago, merging galaxies, vast star-forming nebulae, quasars pumping out huge amounts of energy, aurorae on Saturn, comets, icy objects in the Kuiper Belt, asteroids, and the changing face of Pluto. The telescope also has sent back images known for their beauty as well as their scientific importance.
