So it can be closer to the stars it magnifies
|
|
|
They have very large optical lenses
|
|
|
So its images aren’t distorted by Earth’s atmosphere
|
|
|
So it can be operated by astronauts

Detailed explanation-1: -Telescopes in space orbit the earth and work above the atmosphere. Therefore, they should give detailed images not distorted by the atmosphere.
Detailed explanation-2: -Hubble views the universe with greater precision than Earth-based telescopes because it is not hampered by Earth’s atmosphere. The atmosphere distorts light that travels through it and blurs images taken of outer space.
Detailed explanation-3: -Why is Hubble able to see so much better than telescopes on Earth? Because it is above the Earth’s atmosphere. The atmosphere disturbs the starlight (a bit like looking through water) and blurs the images. So Hubble’s images are much sharper than those from other telescopes.
Detailed explanation-4: -To keep Hubble from gradually falling back toward Earth’s surface, the telescope was boosted into a slightly higher orbit multiple times over the years by the space shuttle following servicing.
