What is the difference between a pulsar and a quasar?
| September 13, 2020 | Education
According to modern concepts, a pulsar is a rapidly rotating neutron star with radio emission. The radio beam emanates from the polar regions of the star, therefore it forms a kind of “searchlight”. The Earth periodically falls under this radiation, so there is a feeling that the star is pulsating. Hence the name.
Quasars are active nuclei of distant galaxies with luminosities trillions of times that of the Sun.
