The cylindrical satellite the size of a school bus was sent into orbit on April 24 1990, after its launch was delayed by the Challenger space shuttle disaster four years earlier.
Hurtling round the Earth at almost 16,800mph at a height of 347 miles, the telescope has transformed our view of the universe, led to astonishing new discoveries about the cosmos, and delivered breathtaking images from the great beyond.
Speaking of the £5.3 billion instrument with which he has been involved from the outset, Royal Astronomical Society president Professor Martin Barstow said: "The scientific and cultural contribution is incalculable. Hubble has measured the size of the universe and contributed to the discovery of Dark Energy, leading to a Nobel prize.
"It has gone on to study planets outside our solar system, a project that could not have been conceived when Hubble was launched, as no such objects were known.
"Its images have coloured all our lives and engaged millions in an exciting scientific adventure."
The Hubble Space Telescope (HST) was named after US astronomer Edwin Hubble (1889-1953) whose work led to the discovery that the universe is expanding.
Let's have a look at some of the spectacular imagery Hubble has sent back to us.
