Few of NASA’s telescopes have captured the public imagination like Hubble, with its spectacular views of distant galaxies, supernovas, and nebulas. The first telescope in the world to return visible wavelength images of space from near-Earth orbit, Hubble’s photos are more than just pretty pictures. In its twenty-five year mission, Hubble’s discoveries have transformed astronomers’ understanding of cosmic objects, events, and history. Hubble continues to deliver unparalleled images and help scientists solve some of the biggest mysteries about the forces that shape the universe.
