Discovering the Unimagined
Hubble has not only furthered our knowledge of the known universe, it’s shocked the astronomical world with never-before-seen phenomena.
When Hubble was launched, no planets around other stars had been discovered, Pluto had only one known moon, and dark energy was not even a concept. With over three decades of observations, Hubble has changed humanity’s understanding of the universe. We now know that black holes exist at the center of almost all galaxies, Jupiter’s massive storm – the Great Red spot – is now shrinking, light can echo just like sound, and the universe is expanding at an accelerating rate. Learn about Hubble’s great discoveries, understand the basics behind Hubble’s scientific capabilities, and explore its incredible images of the cosmos.
