Pulsar =

Neutron Stars turning quickly on itself, and sending a regular interval of radioléléctrique signals.

This is remains the core of a supergiant star after a supernova explosion.
Pulsars rotate on themselves and look like a powerful beacon of the cosmos, sweeping space of their light beams.
The light is visible faster 1000 times per second!
The slower, 1 time every second.
Currently we spotted more than 400 pulsars in the sky through telescopes.

Quasar or quasi-stellar source =

Nucleus of a young galaxy tes, producing an incredible amount of energy.

Quasars are the active cores of young galaxies, or the outbreak of millions of stars occur.
These are also the most distant visible Astres of the Universe.
Their light took more than ten billion years to travel in space jusqua us.
That is what we see today is 10 billion years old, so almost the age of the universe itself (about 13 billion years).
When astronomers observe quasars, they observe what was happening in the Universe just 3 billion years after the Big Bang: they attend early exisentence galaxies!

Pulsars and quasars are seen in the depths of the universe, almost at the very beginning is that the "Big Bang" 13 milliars years.

Each pulsar has a different rotational speed, the slowest performs one revolution upon itself in 1.3 second, faster up to several hundreds of revolutions per second. We must therefore look for pulsars in supernovae.
These pulsars emit energy with wind and solar radiation.

This is called pulsar nebula.

The most famous nebula is the Crab Nebula, discovered in 1968. Pulsars are also famous for their very strong magnetic field.

But that's nothing compared to the magnetar, which have the strongest magnetic fields in the universe.

Pulsars also emit radio waves that can be detected via our satellites, some pulsars emitting sounds like a melody.

Certainly, pulsars and magnetars are considered the strangest objects in our universe, but there are still strange objects.

Certainly, pulsars and magnetars are considered the strangest objects in our universe, but there are still strange objects.

These are the quasars, extremely bright and located at the edge of the universe. 3C273 is the first quasar discovered.

Quasars are gigantic black holes radiate light and devouring matter.



Quasars are therefore situated at the center of galaxies, where there is a supermassive black hole. Today we discovered fifty quasars.

These cosmic monsters send astronomical jets, which remain a mystery to the scientific community.

It is not known how these jets arise. Still, these jets are spread over great distances.

They are also called Dragn and may extend over a distance of 5 to 6 million light years.

These Dragn also correspond to powerful radio waves passing through the galaxies.

The nearest quasar is at two billion light years from us, later, to 13 billion light years.

The first quasars were born after the Big Bang and probably played an important role in the creation of the universe. But how?

That is still to discover these strange objects, both monstrous and fascinating.
 
Back in my college days I speculated that quasars are the opposite end of black holes in another location in space/time. NASA still refuses to return my calls!
 
Hi Iceweasel, there is now a scientific consensus that a quasar is a compact region surrounding a supermassive black hole at the center of a massive galaxy. Their size is 10 to 10 thousand times the Schwarzschild radius of the black hole. Their source of energy comes from the accretion disk surrounding the black hole.

By God. I knew I was onto something. Everybody laughed at me.
 
There is such celestial violence in quasars yet it displays such beauty.
