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.


What did William Herschel build?

He built a telescope. Read about it. It is interesting.


Why aren't infrared telescopes built at low altitudes?

Infrared telescopes are usually built at high altitudes to minimize atmospheric interference. At lower altitudes, the Earth's atmosphere absorbs and scatters infrared light, making it difficult to observe astronomical objects accurately. By placing telescopes at high altitudes, such as on mountain peaks, scientists can minimize the interference and obtain clearer observations of infrared radiation from space.


What are some good telesconpes that have built in cameras?

The best telescopes with built in cameras are made by Samsung and Sony. They are difficult to find and should be purchased from the internet.

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.


How are radio telescopes different from keck telescopes?

Keck telescopes do not exist, Keck telescope refers to the WM Keck Observatory on Mt. Kea.The Keck Observatory is comprised of several opticalreflecting telescopes, whereas aradio telescope consists of a large parabolic solid metal or screen reflector with a radioreceiver at its focus, built to detect and measure radio waves.


What would happen if telescopes weren't built?

As Necessity is the Mother of Invention then someone would need to invent a thing which works like a telescope but may go by a different name and might be better than any telescopes we have


What year was the non optical telescope invented?

The non-optical telescope, primarily radio telescopes, were invented in the 1930s. One of the first and most notable radio telescopes was built by Karl Guthe Jansky in 1931.
