Quasars

Quasars are thought to be galactic black holes which are releasing focused energy from an accretion disk. The temperature could be as high as hundreds of millions of kelvins, but is detected due to its extremely high luminosity.

There are more quasars in faraway galaxies, i.e., in the distant past.

Quasars are highly luminous due to the accretion of mass onto supermassive black holes at their centers. Since their luminosity comes from a small region near the black hole, they must be compact in size. Observations of rapid variability in their light output further support the idea that quasars are small objects, as these changes happen on timescales that would be consistent with a compact source.

The primary source of a quasar's energy is gravitational potential energy. Quasars are powered by the immense gravitational forces surrounding supermassive black holes at the centers of galaxies, which convert this potential energy into light and other forms of radiation.

Quasar is an acronym for quasi-stellar source. It is a 'star' or region with a very bright and regular electromagnetic pulse. There are several such examples the most notable is the Crab nebula.

So you could say 'the Crab nebular is a quasar'.

Light travels at approximately 186,282 miles per second. So, to calculate the time it takes for light to travel 58,656,960,000,000,000,000,000 miles, you would divide the distance by the speed of light. This would give you approximately 315,102,786 seconds or about 9,996 years.

Quasars emit strong radio waves in addition to other forms of radiation like visible light. These radio emissions can be detected by radio telescopes, which is why quasars are sometimes colloquially referred to as "radio stars."

The first quasars were discovered with radio telescopes in the late 1950s. However many were recorded only as radio sources with no visible object. Hundreds of these objects were recorded by 1960 and published in the Third Cambridge Catalogue. In 1960, a radio source was finally tied to an optical object. Astronomers detected what appeared to be a faint blue star at the location of the radio source. In 1962 another radio source, 3C 273,measured by Cyril Hazard and John Bolton during one of the occultations which allowed Maarten Schmidt to optically identify the object and obtain an optical spectrum. This discovery revolutionized quasar observation. The term quasar was coined by astrophysicist Hong Yee Chiu in 1964.

Your question can not be answered exactly as it is asked. Many of the things in the universe come in various sizes. There are Galaxies and there are Super Galaxies. Super Galaxies can be bigger than clusters of galaxies. Planets and Moons come in all kinds of sizes. Some moons are the size of some minor and/or regular planets... such as Ganymede, and Titan for example. Both are larger than Mercury, and the minor planet Pluto. Pulsars are the remnants of a dying star, stars, meteors, and every thing you have asked about come in various sizes as well. I would recommend that you find and watch "The Universe" which I believe is on the Discovery Channel. There is an episode that deals with the largest things in the Universe. According to that source... the largest thing in the Universe is the "Cosmic Web". This show will deal with pretty much everything you have on your list. It is a very interesting show, and it repeats regularly.

To enter codes on the Quasar Tower Universal Remote LSSQO209, first press and hold the "Setup" button until the indicator light comes on. Then, enter the code for your device using the number buttons on the remote. After entering the code, press the "Power" button to test if the code works.

Without a remote, you may not be able to adjust the color settings directly on the Quasar VV2008. You could try to see if there are manual controls on the TV itself, but those are usually limited. Alternatively, you could look into getting a universal remote that is compatible with your TV model to adjust the color settings.

They are called quasars. We occasionally observe short bursts of gamma radiation which outshine even quasars temporarily, but astronomers aren't absolutely certain yet what causes them.

The world record for the most miles on a Scion xB is held by Victor Sheppard, who has driven his 2007 Scion xB for over 1 million miles. He achieved this milestone in 2019 and continues to drive his vehicle daily. Sheppard credits regular maintenance and a love for his car for reaching such a high mileage.

Melons were "discovered" on the third day when God said, "Let there be..." and mature vegetation appeared all over the earth.

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.

That's the current best guess; the formation of extremely powerful black holes in the centers of many galaxies. It's possible that when the central black hole in the Milky Way was forming, our own galaxy might have shined like a quasar.

This may be why we never see any aliens in space; any civilization that existed then might have been exterminated by the radiation released when the central black hole formed. Earth's biosphere formed after that, and we might be one of the first spacefaring species since.

Quasars are the most radiant objects in space. They contain a central black hole surrounded by a disk of gas and dust. They emit large amounts of radio waves but not much visible light.

Gravity. We're not entirely certain what a "quasar" is, but the current theory is that it is a black hole forming and growing in an active galactic core. It is likely that 10 billion years ago, the Milky Way Galaxy was a "quasar", as the supermassive black hole in the center of our own galaxy was forming.

All quasars are located at a great distance from us. Of the quasars discovered, they range from between 780 million and 28 billion light years away.

Because of these distances and the velocity of light, we are seeing them early on in the creation of the Universe. They are very rare they have only found about 20 or so.

Quasars are not dangerous to humans as they are located very far away in distant galaxies. They are powered by supermassive black holes and have immense energy outputs, but their effects are not felt on Earth. Quasars are important for understanding the early universe and the physics of black holes.

They don't.
You have not understood what the theories try to explain.
You will need to do a great deal more reading and learn a great deal more about mathematics before you can approach even a rudimentary knowledge of what is being theorised here.

Quasars have all kinds of spectral lines namely more energetic ones which makes them the brightest objects in the night sky.

Yes, quasars are observed from Earth using telescopes and other astronomical instruments. They appear as distant, extremely bright objects located billions of light-years away at the center of young galaxies.

Chalk is a naturally occurring mineral. The "white cliffs of Dover" are made of chalk. It has been used for marking and painting by many ancient cultures.

Today's 'chalk' that is found in classrooms is a clay composite. It is poured into molds.
