The Hubble Space Telescope (HST) is a space telescope that was launched into low Earth orbit in 1990, and remains in operation.
The Hubble Space Telescope (HST) is the most famous-and probably most successful-space observatory ever flown. The 11 tonne telescope was placed into a 570 km high orbit around Earth by the Space Shuttle in April 1990. Circling our planet every 96 minutes, the HST has so far travelled some 5 billion km. Hubble has sent back a huge amount of scientific data and incredibly detailed images of every type of object in the sky. By autumn 2009, it had made nearly 900,000 observations and snapped over 570,000 images of more than 29,000 objects.
