30 years ago, one of the most famous and awe-inspiring pieces of technology – The Hubble Space Telescope – was launched.
Hitching a ride with the Space Shuttle Discovery in 1990, Hubble was placed in low-Earth orbit, where it has been continuously observing the night sky ever since. Observations have been carried out across all wavelengths of light, from ultraviolet to infrared, which have given astronomers an unprecedented window on the Universe.
So what have they learned from its breath-taking pictures?

SpaceThe cause of gamma-ray bursts
The Hubble Space Telescope saw the ‘smoking gun’ that revealed the secrets of these enormous cosmic explosions.
SpaceHow planetary collisions work
Comet Shoemaker-Levy 9’s impact on Jupiter was captured by the Hubble Space Telescope.
SpaceSupermassive black holes
Black holes are hard to find, but having the Hubble Space Telescope in your toolbelt makes things easier.
SpaceProtoplanetary discs
Our understanding of protoplanetary discs, or proplyds, exploded with a breakthrough from the Hubble Space Telescope.
SpaceThe age of the Universe
The Cepheid stars discovered by the Hubble Space Telescope has helped us pinpoint the age of the Universe.
SpaceExoplanet atmospheres
The Hubble Space Telescope was first to detect the atmosphere of one of these alien worlds.

SpaceGenerations of stars
When the Hubble Space Telescope looked to the stars, it found much more than was expected.
SpaceDark matter
Something is hiding in our Universe, and the Hubble Space Telescope could help us find it.
SpaceHow galaxies evolve
The Hubble Space Telescope was able to find 3,000 galaxies looking at an area of just one 24-millionth of the whole sky.
SpaceAccelerating expansion of the Universe
Hubble Space Telescopes observations found that not only is the expansion of the Universe accelerating but is also being fuelled by ‘dark
