Astronomy Telescopes

Question by John S: Would a radio telescope detect a very big grinding sound?
I know that pulsars emit radiowaves, but how exactly are radiowaves produced?

Best answer:

Answer by Feythe
Radio waves are the longest wavelengths in the EMS (electromagnetic spectrum) and a radio telescope, provided the dish or array was large enough and it was pointed in the right direction, could detect a wave in the radio spectrum.

We can produce radio waves by applying and removing electrical current to a wire. Antenna are used for transmitting and receiving radio waves.

In space, electromagnetic radiation is created when atoms absorb energy (their electrons become excited and move to a higher shell in the atom, then return to their original position).
