The Hubble Space Telescope is a large telescope that orbits the Earth. It was launched into orbit by space shuttle Discovery on April 24, 1990.
Hubble orbits about 547 kilometres above the Earth. It is the length of a large school bus, and weighs as much as two adult elephants.
Hubble does not travel to stars, planets or galaxies. It takes pictures of them as it whirls around Earth.
Hubble is named after an American astronomer Edwin P. Hubble. He showed that the galaxy containing the solar system-the Milky Way – was only one of many galaxies.
His work helped show that the universe is expanding, and this has been proved by the Hubble Space telescope as well.
The Hubble Space telescope helped researchers make important discoveries about our Universe.
