telescopes because they are meant to look into space
Their eyes, ground-based telescopes, space telescopes.
Telescopes on Earth have to look through the atmosphere (air) which distorts the image. Telescopes in space dont have to look through the atmosphere and so the image is a lot clearer.
Telescopes are used to see things that are far away from earth. Using telescopes we can see things that are millions of miles away. Most of the telescopes are on Earth but some of them are in space such as the Hubble Space Telescope.
Telescopes.
Yes, if you look in the right place.
Actually they are.
An Earth-bound telescope is merely a telescope located on Earth. This term is used to distinguish all of our normal telescopes on Earth from space telescopes or orbiting telescopes. The Hubble space telescope is the most famous space telescope, but there are many dozens of telescopes orbiting Earth which look at Earth or the Sun or other objects in space. Obviously, it is easier to construct an Earth-bound telescope and they can be bigger since getting a telescope into space requires a rocket and a lot more engineering and money. Space telescopes have the advantage of being outside the atmosphere and thus no atmosphere to diminish the quality of the image. For infrared telescopes there is the advantage of being in the cold environment of space where the interference from radiations of hot objects on Earth is absent. On the other hand, space telescopes are hard to repair and you can't really be there to look through them.
All space telescopes are unmanned - unless you want to count the small telescopes on the Shuttle or IIS as space telescopes.
they use space probes,satellites,and of coarse,telescopes.
people could look deeper into space with a giant telescope.
Scientists use telescopes, specifically large ground-based telescopes and space telescopes like the Hubble Space Telescope, to study Eris. These telescopes allow them to observe Eris' size, shape, surface features, and composition.
