What is Hubble?
The Hubble space telescope has been in space for almost 30 years. Hubble was created to take pictures of things in space that we could not reach by space travel. Hubble is named after Edwin Hubble who was the scientist who discovered the Universe is expanding. Hubble is also the only space telescope designed to be serviced in space. Hubble has been is space since 1990 and has been serviced four times since then.
How does Hubble Work?
Hubble is able to take high resolution pictures with almost no background light by absorbing the light which then bounces off of a primary concave mirror. The light then goes to the secondary convex mirror. The secondary concave mirror focuses the light through a hole in the center of the primary convex mirror which leads it to Hubble's instruments where it is able to take pictures. The mirrors help Hubble absorb more light which allows for better images in the vacuum of space.
What has Hubble Seen?
Hubble has seen almost everything in our own galaxy and is now exploring other galaxies. Here are just a few examples. Hubble has photographed Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus Neptune, a vast number of nebulae, including the Crab Nebula , the Orion Nebula, etc.). Most recently, Hubble has captured images of the star Icarus which broke a world record for the farthest lone star photographed. Here are some pictures that hubble has taken.

How big is Hubble?
Hubble is 13.2 meters long and weighs 11,110 kilograms. Although this sounds massive, Hubble is one of the smaller telescopes used by NASA. Here is a picture of Hubble's mirror compared with other telescope's mirrors. (Hubble's mirror is the one right next to
James Webb space telescope),
