Quasars appear as faint red stars to us here on Earth. They emit radio waves, x-rays and light waves. This radiation can be observed only when a beam of emission is pointing toward Earth (similar to the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance. These emit high-energy electromagnetic radiation via magnetic field decay in bursts of x-rays and gamma rays.

Quasars got that name because they looked starlike when astronomers first began to notice them in the late 1950s and early 60s. Quasars are the brightest objects in our universe, although to see one through a telescope they do not look that bright at all. A pulsar (from pulsating radio source) is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. s 1,000 trillion times more powerful than earth’s magnetic field and 100 to 1,000 times more intense than a radio pulsar. What is a quasar The word quasar stands for quasi-stellar radio source. The activity in these galaxies is caused by a giant black hole at their very heart, pulling in material from its surroundings, tearing it to shreds and heating it up to tremendous temperatures before swallowing it up. #color(white)000000000000000000000# The Vela Pulsar JetĪ quasar (from ‘quasi-stellar radio source’) is, in fact, a distant galaxy with a fluctuating blaze of light and other radiations coming from its central regions. There are many models but no accepted theory". "The theory of how pulsars emit their radiation is still in its infancy, even after nearly forty years of work. Quasars belong to a family of stellar objects known as 'Active Galactic Nuclei' or AGN. At the left is an artists conception of a quasar.

A pulsar is a rapidly rotating neutron star with a strong magnetic field. Pulsars have pulse and rotation, while quasars do not. It is limited to 32-amps (7.4 kW), which. Key Differences between Quasar and Pulsar Pulsars are highly magnetized rotating neutron stars, while quasars are extremely powerful and distant active galactic nuclei. It has a powerful magnetic field, shooting out jets of radiation that sweep across space like lighthouse beams – when they line up with Earth they appear as a rapidly repeating burst of light, radio waves and other radiations. The word 'pulsar' is a shortened version of 'pulsating star' and was coined in 1968. The Quasar is a DC charger that offers bidirectional capability, meaning it can charge your car and also feed energy from your car's battery to your home. Despite their confusingly similar names, these are very different celestial objects.Ī pulsar (originally short for ‘pulsating star’) is a rapidly spinning neutron star – the remnant of a supernova explosion.
