NASA’s Hubble Space Telescope is celebrating its 30th birthday!

The Hubble Telescope was launched on 24 April 1990. It is one of NASA’s most valued observatories.

Currently, the telescope is orbiting the earth 550km above Earth. It has beamed back images that have completely changed our understanding of the universe!

Hubble has proved black holes exist, shown that space isn’t empty, and helped to find new planets.

The Hubble uses a big curved mirror lens to help it take pictures. When it was first put in space experts found that the edge of the mirror had been ground down too flat by a depth of four microns (that’s around one-50th the thickness of a human hair!).

Three years later a group of astronauts were launched into space to help fix the telescope.
