The Hubble Space Telescope, launched in 1990, uses a large hyperbolic mirror to take highly detailed astronomical photographs. Hubble's orbit outside Earth's atmosphere allows it to take extremely sharp images without distortion or light pollution.
There is minimal atmospheric disturbance up where the Hubble orbits. Down here on Earth we have to contend with the atmosphere.
The Hubble Telescope uses both mirrors and lenses to focus on images.

The (GMT) Giant Magellan Telescope .
Hubble does not have to contend with the atmosphere of the earth which bends and distorts images from earth-based telescopes.
We understand earth and space more because of it.
adaptive optics
The problem with ground based telescopes is that the atmosphere distorts images, The Hubble space telescope is above the atmosphere and therefore can view with much better clarity.
When they started getting images back from the Hubble, thee was a distortion that should not have been there, and it was keeping the telescope from capturing really good images. It later turned out that there had been a mistake made in grinding the curved mirror.
Launched on April 24th 1990 the purpose of the Hubble space telescope is so astronauts and astronomers and even the public can discover new images of our Galaxy and other Galaxy's and other planets
It's a space telescope, meaning that it can get a good view of things out in space without any disturbance from the earths atmosphere. Being in space means that is can magnify images to a higher degree than earth telescopes, providing much more detailed images.
