It measures hydrogen from which stars are formed.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
No they are not bigger then radio telescopes at all.
Astronomers use radio telescopes, infrared telescopes, and space-based telescopes to map the shape of the Milky Way. They measure the positions and motions of stars, gas, and dust to create a three-dimensional map of our galaxy.
Radio telescopes gather data from radio sources and they target the radio frequency part of the electromagnetic spectrum.
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.
No, radio telescopes and refracting telescopes have different designs and functions. Radio telescopes are designed to detect radio waves from space, whereas refracting telescopes use lenses to bend light to create images of distant objects. While both types of telescopes have a common goal of observing the universe, their designs are optimized for different wavelengths of electromagnetic radiation.
Radio Telescopes and radio wires
using radio waves it collects the data.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
As far as I know, there is no "optical radio telescope". There are, separately, optical telescopes (which work with visible light), and radio telescopes (which work with radio waves).
Light telescopes which are refractor and reflector and radio ones.
Not necessarily.
