10 of the Hubble Space Telescope’s greatest discoveries

The Hubble Space Telescope has been observing the Universe for 30 years. We look back at some of its most incredible discoveries.

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?

The Hubble Space Telescope saw the ‘smoking gun’ that revealed the secrets of these enormous cosmic explosions.

Comet Shoemaker-Levy 9’s impact on Jupiter was captured by the Hubble Space Telescope.


Black holes are hard to find, but having the Hubble Space Telescope in your toolbelt makes things easier.

Our understanding of protoplanetary discs, or proplyds, exploded with a breakthrough from the Hubble Space Telescope.

The Cepheid stars discovered by the Hubble Space Telescope has helped us pinpoint the age of the Universe.

The Hubble Space Telescope was first to detect the atmosphere of one of these alien worlds.
