What do astronomers use to look at planets?
Their eyes, ground-based telescopes, space telescopes.
What are the advantages of ground-based telescopes?
Ground-based telescopes are typically larger and more cost-effective than space telescopes. They can be easily upgraded and repaired, and have the ability to be built in remote locations for better viewing conditions. Additionally, ground-based telescopes benefit from continuous improvements in technology and instrumentation.
The Hubble Space Telescope obtains higher-resolution images than most ground-based telescopes because it is?
Only because it gets no atmospheric interference, which most of the ground based telescopes do.
Which of the following is not an advantage the Hubble Space Telescope has over ground based telescopes?
The Hubble Space Telescope is not affected by atmospheric distortion, providing clearer images than ground-based telescopes. Ground-based telescopes have the advantage of being easier to upgrade and maintain than a space-based telescope like the Hubble.
Why do astronomers currently prefer orbiting telescopes over earth based telescopes?
Orbiting telescopes are located in the sky, where it is not affected by the turbulence of the atmosphere, while ground-based telescopes are located on the ground, where the atmospheric turbulence (the moving of air) is greater. This is also the reason that some telescopes are built on mountains where the atmosphere is thinner and turbulence is smaller.
Do astronomers use ground-based X-ray telescopes?
Yes, astronomers use ground-based X-ray telescopes to study high-energy phenomena in space. These telescopes are typically located at high-altitude sites to reduce interference from Earth's atmosphere and are used to observe sources such as black holes, neutron stars, and supernova remnants.
What are the major types of optical telescopes?
Ground-based telescopes, and space telescopes. Or: refracting telescopes (main collector is a lens), and reflecting telescopes (main collector is a mirror). Or: Home telescopes (small ones), and professional ones (larger and more expensive).
Why are astronomical IR telescopes deployed well above the cloud but never on the ground?
Ground based telescopes are not as effective at these observations because infrared light is largely blocked by water in Earth's atmosphere.

What is an advantage of using orbiting telescopes rather than ground based telescope?
There is no distortion from Earth's atmosphere.
What tools are used to study Eris?
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.
Why can hubble space telescopes see much further into space and product much clearer images then telescopes on earth?
Because light is absorbed and disturbed as it passes through air ... effects that ground-based telescopes have to live with but Hubble doesn't.
