What is special about the Hubble Space Telescope?

Earth's atmosphere changes and blocks some of the light that comes from space. Hubble flies around, or orbits, high above Earth and its atmosphere. So, Hubble can see space better than telescopes on Earth can. Hubble is not the kind of telescope that you look through with your eye.
NASA's Hubble Space Telescope is the first major infrared-optical-ultraviolet telescope to be placed into orbit around the Earth. Located high above Earth's obscuring atmosphere, the telescope has provided the clearest views of the universe yet obtained in optical astronomy.
Hubble Telescope Captures Farthest View of the Universe Yet. The Hubble Space Telescope's eXtreme Deep Field image allows scientists to see galaxies more than 13 billion light years away.
