radio astronomy, study of celestial bodies by means of the electromagnetic radio frequency waves they emit and absorb
Radio waves, also known as "radio frequency" (RF), are a type of electromagnetic radiation with wavelengths ranging from about 1 mm to over 100 km and frequencies from 1–300 MHz. They are used in various fields such as communication, navigation, radar, medical imaging, astronomy, and indus...
In radio astronomy, a fast radio burst (FRB) is a transient radio pulse of length ranging from a fraction of a millisecond to a few milliseconds, caused by some mysterious high-energy astrophysical process that has not yet been discovered. Astronomers estimate the average FRB releases as much...
it intercepts radio waves, which create a feeble current in it. The current is then amplified in a radio receiver until it is strong enough to measure or record. Like your television or radio, receivers can be tuned to select a single frequency (channel). In astronomy, however, it is mor...
