The Hubble Space Telescope was launched by NASA on 24th April 1990 attached to the Space Shuttle Discovery. The next day, Hubble was released into low Earth orbit, opening a new chapter in humanity’s understanding of space. During its 25 years, Hubble has provided over one million observations, noted 38,000 celestial targets and has circled Earth more than three billion times, travelling at a speed of 17,500 mph.
The Hubble Space Telescope has a primary mirror of 2.4 metres and records hundreds of thousands of very high resolution images which it beams back to Earth. By orbiting outside the distortion of the Earth’s atmosphere, it is able to capture images with almost no background light, making them the most visible images of space ever. Eight such images feature on the stamps within this commemorative issue.
