Pulsars(short for PULSAting Radio Stars) are highly magnetized rotating neutron stars that emit a beam of electromagnetic radiation in the form of radio waves. Their observed rotational periods range from 1.4 ms to 8.5 seconds The radiation can only be observed when the beam is pointing towards the Earth. This is called the "lighthouse effect" and gives rise to the pulsed nature that gives pulsars their name. Because neutron stars are very dense objects, the rotation period and thus the interval between observed pulses are very regular. For some pulsars, the regularity of pulsation is as precise as an atomic clock. Pulsars are known to have planets orbiting them, as in the case of PSR B1257+12.

A quasar (contraction of QUASi-stellAR radio source) is an extremely powerful and distant active galactic nucleus. They were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light that were point-like, similar to stars, rather than extended sources similar to galaxies. While there was initially some controversy over the nature of these objects, there is now a scientific consensus that a quasar is a compact region 10-10000 Schwarzschild radii across surrounding the central supermassive black hole of a galaxy. It is a very large object at the centre of a very distant, and hence very old, galaxy. It has a mass of thousands or even millions of times that of our sun. As matter is dragged into it, it emits huge amounts of radio waves, but because it is so far away it appears to us as a point source - hence quasi stellar.

Is a galaxy similar to a quasar and pulsar?

No, not in the slightest sense. A quasar, pulsar, and galaxy are three very different things.

That would be called a "pulsar". See related question

Pulsar Quasar Radial(?) These are all names for some variety of "star"


Why would astronomers be interested in the difference between a black hole and a quasar?

They are separate phenomenon and different principals are in action.


What conducts radio waves through space?

Radio waves are not conducted. They propagate. They do not need a medium through which to propagate. They just move.


Which is more powerful a quasar or a hypernova?

Depends on how you look at "power" I suppose, but a quasar is similar to a pulsar in that it has high enough angular velocity to produce jets of EM and synchrotron radiation through it's poles but however, a quasar is orders of magnitude larger than a pulsar since a pulsar is just a single neutron star (Maybe 20-30km in diameter) while the quasar is a entire galactic nuclei.


What is the difference between a galaxy and a pulsar?

A galaxy is a massive collection of stars, most orbiting around a supermassive black hole.A pulsar is a rapidly rotating neutron star that emits a beam of electronic radiation.See related questions.


What is the difference between a quark and a quasar?

Magnitude - sheer size.A quark is tiny - it takes 3 to make a single proton.A quasar is a "quasi star" and is actually an entire galaxy with its core on fire(not actual fire with flames, but in the act of constantly blowing up).


What is the difference between a neutron star and a pulser?

If they are both young - nothing. The only difference between the two is that a pulsar has one of it's poles pointing towards Earth - so we can detect the "pulse". See related questions.


Which is better pulsar 135 or pulsar 150?

First of all, the main distinguishing factor between Pulsar 150 and Pulsar 135 is the cost. Pulsar 150, as the name says, 150cc has more power, pick up and speed when compared to Pulsar 135. But, pulsar 135 has also got the equivalent features of Pulsar 150. (Because of the latest technology) In a nutshell, Pulsar 135 is a lite version of Pulsar 150. And, my opinion, Pulsar 150 is better...

It is not.


What is a star catalog?

A listing of stars. It will include the star's name, celestrial location and brightness, as well as color and other key notes (binary star, pulsar, quasar, etc.). It may also include such things as who discovered it and when.
