Radio Telescopes and radio wires
The pulsing radio waves from the discovered object were detected using radio telescopes that can pick up and analyze radio signals emitted by celestial objects in space.
Radio waves were detected in space for the first time in 1938. At the time, radio waves traveled around 60 light years away.

Radio waves are one example.
No, electromagnetic waves such as radio waves, microwaves, and visible light are not able to be detected by the sense of smell because they do not have a scent. These waves are typically detected by instruments or devices designed to pick up their specific frequencies.
MRI machines use radio waves to magnetize the hydrogen atoms in the body. When the radio waves are turned off, the hydrogen atoms release energy in the form of radio waves that are detected by the MRI machine to create an image of the internal structures of the body.
An example of a signal that carries information and can be detected is an electromagnetic wave, such as radio waves or light waves. These waves can encode data and be received by antennas or sensors for further processing and interpretation.
astronomy using radio waves, rather than visible light. visible light and radio waves are essentially the same, only radio waves have a much longer wavelength. not everything emits light in the visible band, many otherwise invisible objects can only be detected using extreme wavelengths.
Radio waves beyond our solar system were first detected by astronomers using radio telescopes, with notable contributions from the team led by Jocelyn Bell Burnell and Antony Hewish in 1967. They discovered pulsars, which are highly magnetized rotating neutron stars that emit beams of radio waves. This groundbreaking detection expanded our understanding of astrophysical phenomena and opened up a new field of study in astronomy. Subsequent advancements in radio astronomy have allowed for the exploration of various cosmic sources of radio waves beyond our solar system.
Radar uses radio waves for detecting and tracking objects. These radio waves are emitted by the radar system and bounce off nearby objects, with the reflected waves then being detected by the radar receiver to determine the object's location and speed.
