What is a super heated quasar?
Quasars or quasi-stellar radio sources are the most energetic and distant members of a class of objects called active galactic nuclei (AGN). Quasars are extremely luminous and were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light, that appeared to be similar to stars, rather than extended sources similar to galaxies. They cannot escape a black hole. Only Hawking Radiation can escape a black hole.
How do you measure the size of a black hole?
The size of a quasar can be inferred from the timescale of variations in its light output. Assuming that no signal can travel across the source faster than the speed of light, the time scale of the fastest variations sets an upper limit on the size of the quasar (i.e., size quals approximately the variation timescale times speed of light). An alternative method called 'reverberation mapping' monitors changes in the quasar's light output, then looks for these same changes in the light output from specific spectral lines. The delay times the speed of light gives the size of the quasar.
What is a quasar in space?
Quasars are: quasi-stellar radio sources. The consensus now is that: quasars (the most luminous objects in the Universe) are compacted regions in the middle of massive galaxies. Quasars owe their high energy to the accretion discs surrounding massive black holes at the center of these galaxies.
What two things does the central engine if a quasar contain?
The central engine of a quasar contains a supermassive black hole at its core, which is surrounded by an accretion disk of hot gas and dust. The intense gravitational forces and high temperatures within the accretion disk lead to the emission of powerful electromagnetic radiation, making quasars some of the brightest objects in the universe.
What is superheating?
Super heated to remove excessive moisture
Is a quasar a galaxy with a super-massive black hole in its center?
Yes, a quasar is a galaxy with a super-massive black hole in its center. The hole being invisible, all light vanishing from the great gravity. The quasar itself, among the brightest, most luminous objects in the universe, is being powered by an accretion disc around the black hole.
What is a blazar?
A blazar is a compact quasar, associated with a super-massive black hole at the centre of an active galaxy.
What is the line through the middle of a quasar?
A quasar is a lot like a black hole, in that it was once a star. There are many spikes that do project from the center of the quasar. These are optical spikes. they are like a glare that the telescopes see when they look at a star. if you look at the sun off of a mirror, you can see the same optical spikes from the sun. It is basically a You can also see another line that extends from both sides of the quasar. These lines that you see are actually super heated gas that has been shot out from the center of the quasar. These streams extend many light-years away from the quasar. If you want to learn more, look at some of the Hubble pictures of quasars.

How much brighter is quasar than the sun?
Immeasurably more brilliant. A quasar (quasi-stellar radio source) is as bright as some entire GALAXIES. We believe that a quasar is an actively-expanding super-massive black hole, and that these black holes may exist in the centers of many or most large galaxies - including our own Milky Way.

Who are some super heroes that begin with the letter Q?
The Question, Quasar.
Is the super massive black hole the largest black hole?
Black hole is a location in space that possesses so much gravity, nothing can escape from its pull. Yes, Super massive black hole is the largest black hole.
How heavy is a quasar?
A quasar is not a physical object that has weight, as it is a highly energetic and distant celestial object powered by a supermassive black hole at the center of a galaxy. The mass of a supermassive black hole in a quasar can range from millions to billions of times the mass of our sun. However, it is important to note that the weight of a quasar itself cannot be accurately determined due to its complex nature and distance from us.

Could quasars be imploding black holes?
Quasars - short for "quasi-stellar radio objects" - are believed to be the super-massive black holes in the cores of large galaxies as they are in the process of forming, merging, and consuming nearby stars and star systems. It is likely that our own Milky Way was once a quasar, but that the super-massive black hole has already consumed most of the nearby mass and settled down to a tranquil old age.
