Answer:
Radio signals from neutron stars are produced through a phenomenon known as pulsar emission. Neutron stars are extremely dense objects formed from the remnants of massive stars that have undergone supernova explosions. They have incredibly strong magnetic fields, and when they rotate rapidly, they emit beams of electromagnetic radiation.
As a neutron star rotates, these beams of radiation sweep across space like the beam of a lighthouse. When the beam points in the direction of Earth, we detect it as a regular series of pulses, hence the name "pulsar."
These radio signals are received by radio telescopes on Earth, which can detect the periodic pulses of radiation. By analyzing the timing and characteristics of these pulses, astronomers can learn a lot about the properties of neutron stars, such as their rotation rates, magnetic fields, and even the presence of planets orbiting around them.
