Window on the Universe

The Hubble Space Telescope (HST) has been taking stunning images of space for 20 years. It is one of the largest and most versatile space telescopes and its orbit outside the distortion of Earth's atmosphere allows it to take extremely sharp images with almost no background light. As an observatory in space, Hubble is one of the most successful scientific projects of all time, both in terms of scientific output and its immediate public appeal. It has consistently delivered super-sharp images and clean, uncontaminated spectra over the entire near-infrared and ultraviolet regions of the electromagnetic spectrum. Hubble's observations have opened up new scientific territory and have led to major breakthroughs in astrophysics, such as accurately determining the rate of expansion of the Universe.
