Hubble Space Telescope Poster. Key Ring

Hubble Space Telescope Poster. Launched in 1990, the Hubble Space Telescope is a large, space-based observatory that has revolutionised astronomy. Hubble has observed planets inside and outside our solar system and some of the most distant stars and galaxies yet seen. Exoplanets, which are planets outside our solar system, are incredibly hard to image directly due to how far they are from Earth, and their proximity to bright stars. More than 30 years after launch, Hubble continues to investigate the atmospheres of transiting exoplanets, and remains one of our most valuable and successful windows on the cosmos.​
