What is a distant extremely bright galaxy with the black hole at Center called?
The most luminous and distant objects known to science are called quasars and generally accepted to be the nuclei of active galaxies, or in other words supermassive black holes with their relativistic polar jets aimed towards earth.
How many quasars are there?
A Quasar is a powerfully energetic and distant galaxy with an active galactic nucleus surrounding a super massive black hole. Quasars show where massive black holes are growing rapidly (via accretion). These black holes grow in step with the mass of stars in their host galaxy.Therefore there are going to billions or trillions of stars - many more than our own galaxy (~400 billion).
Why do astronomers think that quasars represent an early stage of galactic evolution?
There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.
Are quasars possible?
Yes they are. Thanks mainly to the Sloan Digital Sky Survey, more than 200,000 quasars are known.
Is everything in the universe stationary?
No. More accurately, nothing in the universe is stationary. There is no single fixed reference point in the expanding universe, and all known astronomical objects are in motion with respect to one another.
Are there a lot of quasars in the universe?
There are about 12,000 known quasars today. I'm sure that as our telescopes get better, that number will go up. As a guess, I would estimate a lot.
What is the most powerful star in the universe?
Depends on how you define power. If we take it as transferring energy then it will have to be the most luminous. So the most luminous star known in the Universe is R136a1
Does a quasar have very little energy?
No. Quasars have the highest energy output of any type of object in the known universe.
What is the non luminous material?
The objects/bodies which do not produces(emits) light on their own are known as non-luminous material. For ex- moon
What is the definition for Luminous and non luminous?
"Luminous" means emitting light (conveniently measured in units known as Lumens). Synonym would most often be "glowing".

How hot is a quasar compared to other celestial objects in the universe?
Well right there friend, a quasar is one of the hottest and brightest objects in our universe when we take a closer look at it. It can shine brighter than thousands of galaxies combined, which shows how powerful and radiant it truly is. Just imagine the warmth and light it brings into the vast expanse of space!

Why were quasars first called ''radios stars''?
Quasars are the brightest and most distant objects in the known universe. In the early 1960's, quasars were referred to as radio stars because they were discovered to be a strong source of radio waves. In fact, the term quasar comes from the words, "quasi-stellar radio source". Today, many astronomers refer to these objects as quasi-stellar objects, or QSOs. As the resolution of our radio and optical telescopes became better, it was noticed that these were not true stars but some type of as yet unknown star-like objects. It also appeared that the radio emissions were coming from a pair of lobes surrounding these faint star-like objects. It was also discovered that these objects were located well outside our own galaxy. Quasars are very mysterious objects. Astronomers today are still not sure exactly what these objects are. What we do know about them is that they emit enormous amounts of energy. They can burn with the energy of a trillion suns. Some quasars are believed to be producing 10 to 100 times more energy than our entire galaxy. All of this energy seems to be produced in an area not much bigger than our solar system.
What is the largest explosion ever recorded in the universe?
Quasars are the most luminous, powerful, and energetic objects known in the universe. They tend to inhabit the very centers of active young galaxies and can emit up to a thousand times the energy output of the Milky Way. Basically, they are galaxies with extremely luminous nuclei outshining their parent galaxy by several hundred times, caused by a high redshift source of electromagnetic energy (radio waves, visible light, etc.) at a compact region in the center of the galaxy surrounding the theoretical supermassive black hole. The most luminous quasars radiate at a rate that can exceed the output of average galaxies, roughly equivalent to one trillion suns!The energy source to such stupendous activity is theoretically considered to be an accretion of matter into a supermassive black hole expelled as pure energy in cataclysmic bursts generated outside the event horizon by gravitational stresses and immense friction on the incoming material.In answer to your question, the most extreme quasar currently known for being the least distant, optically brightest from Earth, and the most powerful quasar radio source is 3C 273.

What objects are decomposable?
Everything in the known universe decomposes, with the possible exception of protons
