This sound that you hear from the Radio, was carried to you by the radio waves thru Ether from the radio stations that could be away from you by tens of kilometers. also the radio telescopes can catch the radio waves that's coming from a very far stars throughout the universe and it could take millions of years to travel from it's source to reach Earth before been picked up by the Radio telescope. These radio waves were discovered by coincidence by the wireless technology engineer Carl Jansky where he noticed this type of radio waves that his wireless radio is picking up some radio Galactic signals when he directs his radio antenna towards the milky way Galaxy. Most types of these observatories are established in a far away places from crowded cities and in a high places from the ground in order to bring best results, be away from radio attenuation and have a clear vision of the night sky. The radio telescopes are made of connected together metal sheets in a form of a giant concave plate that is called "the reflector" and it has an antenna in the middle that is perpendicular to its center, the

and the reflector works in manner that it reflects the galactic radio waves towards it's antenna in it's center, and the antenna by it's turn drives the received signals to a device called "The Receiver" which by it's turn interprets the signals in a manner that could be plotted on the screen as linear slopes. The Radiation Astronomy Science is specifies in a particular type linear slopes that are generated by the galactic radio waves. The astronomer relies on some tools that interprets these waves in order to analyse the star characteristics, like how far, how big, age, direction, temperature,

spinning speed, formation, and mass of the star. Many stars emits a large quantity of radiation waves including our sun, and most of these signals have been observed and interpreted and this
scientific research field has been enriched throughout the period since it was discovered. But there are the remnants of supernovae "Pulsars" and "Quasars" that emits a huge amount of radio waves in a specific frequency, these types of stars has a specific characteristics where it's mass is very dense and one square meter of it's mass weighs millions of tons, these type of "Pulsars" can

destroy any present mass in it's radio field in a milliseconds. this type of stars was discovered in 1967, and it was known as small stars, where some of these stars has a diameter of 30 kilometers, and it spins around itself in an imaginary speed, some can spin in less than a minute around itself and some can spin in one millisecond.
