A. Radio telescopes have led to the discovery of hundreds of cosmic objects that emit radio waves. Most of these cosmic objects can be identified by the optical

telescopes. With the help of radio telescopes, pulsars were discovered.

Pulsars are stars that send out pulses of light and radio waves in regular bursts of energy. For example, a pulsar in the center of the Crab nebula at a distance of 6000 light-years from the Earth sends outbursts of light and radio waves 30 times a second.

Quasar an abbreviation of 'quasi-stellar radio source', is a star-like object situated billions of light-years away, are the radio sources. Not all quasars are radio sources. Since the electromagnetic waves from quasars are being detected on the Earth, and after observation, it shows they send out huge amounts of energy. Quasars are comparatively small in size but it emits 100 times more energy than the entire Milky Way Galaxy.
