telescopes cannot see beyond are so called light sphere, and that is that anything more than 13.7 Billion Light years cannot be seen as the light from it has not reached us yet, but everyday new light is reaching us, but very slowly and its usually just galaxies seen as dots.

How light and radio telescopes are different?
Light telescopes, such as optical telescopes, focus on visible light to observe celestial objects, while radio telescopes detect radio waves emitted by these objects. The design of optical telescopes involves lenses or mirrors to collect and concentrate light, whereas radio telescopes use large parabolic dishes to capture and amplify radio signals. Additionally, optical telescopes are limited by atmospheric conditions and light pollution, while radio telescopes can operate effectively through clouds and at night. This leads to different applications and discoveries in astronomy for each type of telescope.
What are the disadvantages of telescopes?
Some disadvantages of telescopes include limited field of view, susceptibility to atmospheric conditions such as turbulence and light pollution, and the need for regular maintenance and calibration to ensure optimal performance. Additionally, high-quality telescopes can be expensive and may require specialized expertise to operate effectively.
What are the advantages and disadvantages of X Ray telescopes?
Advantages of X-ray telescopes include the ability to capture high-energy emissions from objects such as black holes and neutron stars, providing valuable information about these phenomena. However, X-ray telescopes are limited by Earth's atmosphere, which absorbs X-rays, necessitating the need for them to be placed in space. Additionally, X-ray telescopes tend to have lower resolution compared to optical telescopes.
What other kinds of radiation are detected by telescopes?
Researchers use all of these: -- optical telescopes -- radio telescopes -- x-ray telescopes -- infra-red telescopes -- ultraviolet telescopes
Why have no large refracting telescopes been built since 1900?
Refracting telescopes suffer from chromatic aberration, refracting telescopes have several surfaces to shape and polish, making large glass lenses without interior defects is very difficult, and large glass lenses are more difficult to support than large mirrors.
What are two problems with refracting telescopes?
Images are not always clear because the light is being bent.The size of the lens is limited which limits the power of the telescope.
Radio telescopes are often connected together to do interferometry What is the primary problem overcome by radio interferometry?
The primary problem overcome by radio interferometry is the limited resolution of individual telescopes. By combining signals from multiple telescopes, interferometry creates a virtual telescope with a larger diameter, which improves the resolution and allows astronomers to see finer details in the radio sources being observed.
Most telescopes are telescopes?
refracting
Are optical telescopes much bigger then radio telescopes?
No they are not bigger then radio telescopes at all.
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
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).
Where are telescopes generally found?
