Question

Quizplus · Accepted Answer

Quasars are objects that emit large amounts of radio wave energy and are very distant from Earth, with some being billions of light-years away. They are believed to be powered by supermassive black holes at the centers of galaxies. Pulsars, on the other hand, are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation, including radio waves. Galaxies and black holes are both much larger and their radio wave emissions are not typically as intense as those from quasars.
