We learned about the Hubble Telescope. The Hubble Space Telescope is 13.2metres long (length of a school bus).

It weighs 11,110 Kilogrammes (weight of 2 African elephants.

In the 1920’s Edwin Hubble discovered that the universe was much larger than was previously thought and that it was expanding all the time. As a result of his discoveries scientists named The Hubble telescope after him. The Hubble Telescope was launched into space in April 1990 because images taken by telescopes on earth are distorted by turbulence in the atmosphere. Hubble is located about 547 km above Earth’s surface where it completes 15 orbits every day and is considered to one of the most significant advances in astronomy since Galileo’s telescope in the 1670s. It is used to observe the most distant stars and galaxies as well as the planets in our solar system.

Hubble is to be replaced by the James Webb Space Telescope on December 18th 2021. The James Webb Telescope is 100 times stronger than the Hubble. It will change how we see the universe. In the first picture we see The James Webb Space Telescope.
