What is the device used to detect the radio waves from outer space?
A
Spitzer space telescope
B
Hubble space telescope
C
Radio telescope
D
Lunar 2
Explanation: 

Detailed explanation-1: -A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky.

Detailed explanation-2: -Parts of a Radio Telescope Radio telescopes are built in all shapes and sizes based on the kind of radio waves they pick up. However, every radio telescope has an antenna on a mount and at least one piece of receiver equipment to detect the signals.

Detailed explanation-3: -Devices used to detect radio waves from objects in space are called radio telescopes. Radio telescopes are large dishes made out of metal that reflect radio waves to a central point called an antenna.

Detailed explanation-4: -It’s not unusual for astronomers to detect radio signals in space. In fact, in the field of radio astronomy, telescopes continually pick up signals emanating from pulsars, black holes, massive galaxies, stars and numerous other cosmic phenomena.

Detailed explanation-5: -Radio telescopes are used to study radio waves and microwaves between wavelengths of about 10 meters and 1 millimeter emitted by astronomical objects. Radio waves with wavelengths longer than about 10 meters are absorbed and reflected by the Earth’s atmosphere and do not reach the ground.
