With the naked eye, you can see stars up to about 1000 light years away. You can also see the Andromeda Galaxy. That's about 2.5 million light years away.
That's the most distant object visible to the naked eye. Binoculars show it easily.
With a 3" refracting telescope can see stars down to at least magnitude 9, plus some galaxies beyond Andromeda.
The biggest telescopes can see to over 10 billion light years.
What else can I help you with?
What are space telescopes used to look at?
the sky
What do astronomers use to look at planets?
Their eyes, ground-based telescopes, space telescopes.
Why do you need to put some telescopes in space?
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.
What do most telescopes collect and focus?
Most telescopes collect and focus light from distant objects in space, such as stars, planets, and galaxies. This focused light is then magnified and analyzed by astronomers to study and make observations about the universe.
Are telescopes found in space Yes or No?
Yes, if you look in the right place.
What tools do scientists use from space to study space Why can they only be used from space?
telescopes because they are meant to look into space
What do scientists use to look into space?
Scientists use telescopes, both ground-based and space-based, to observe objects in space. These telescopes collect and detect various forms of electromagnetic radiation, including visible light, radio waves, and gamma rays, allowing scientists to study celestial objects such as stars, planets, and galaxies.
Why are optical space telescopes able to see deeper into outer space than land based optical telescopes?
Optical space telescopes are not affected by atmospheric turbulence, which can distort images and limit the clarity of ground-based telescopes. Additionally, they can be positioned above the Earth's atmosphere, avoiding interference from light pollution and atmospheric absorption. This allows them to capture clearer and more detailed images of distant objects in space.
How have improved giant telescopes have helped in the study of space?
people could look deeper into space with a giant telescope.
Two reasons for sending telescopes into space?
One reason for sending telescopes into space is so that people can get a better look at the stars the second reason for this is so that scientist can discover more about stars.
What is an Earth telescope?
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.
Do optical telescopes allow us to study the visibal light radiated from stars?
Yes, optical telescopes are specifically designed to study visible light radiated from stars. They collect and focus visible light from stars to provide detailed images and spectra, allowing astronomers to analyze the properties of stars such as temperature, composition, and motion.
