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.

Quasars were discovered in the early 1960s by astronomers through radio observations. The first quasar identified was 3C 273 by Maarten Schmidt in 1963, challenging our understanding of celestial bodies' extreme brightness and energy output.

There probably was many before this though.

Why are quasars called radio stars?
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."
What are quasars and where are they found in the universe?
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. See related link for more information.
Why are there no quasars left?
Quasars are not gone; they are still observed in the universe. Quasars are powered by accretion of material onto supermassive black holes at the centers of galaxies, which can make them appear as some of the brightest and most powerful objects in the universe. However, the number of observed quasars may be influenced by factors such as the current stage of galaxy evolution or observational limitations.
Are quasars the most unusual type of active galaxy?
Quasars are the unusual type of active galaxy in the universe.
How many quasars are in a galaxy?
Typically, a galaxy may contain one or a few quasars. Quasars are incredibly luminous objects powered by supermassive black holes at the centers of galaxies. They are rare and only occur under specific conditions, so it is not common for a galaxy to have multiple quasars.
What year were quasars first discovered?
The first quasars were discovered in the 1950's
Which was discovered most recently DNA atomic power radio waves or pulsars and quasars?
pulsar and quasars
What was discovered recently DNA pulsars quasars atomic power or radio waves?
None of them. They were all discovered a good many years ago.
What does the word quasar stand for?
The word quasar refers to a quasi-stellar radio source. Quasars are astronomical bodies that produce vast amounts of energy. The first Quasars have been discovered in the late 1950s.

Are there any discoveries of active black holes?
Yes. Several quasars have been discovered; they are black holes, and they are quite active.
This theory lost its appeal when astronomers discovered quasars and cosmic background radiation?
In Cosmic Physics for $1000, Alex, "What is the Steady State Universe?"
Are distant objects in space called quarks or quasars?

How a quasars are formed?
Quasars are thought to be distant super-massive black holes.
Are quasars the size of the solar system?
Yes. Quasars are the size of the solar system.
Do all quasars have host galaxies in them?
Quasars do not have galaxies in them, quasars are at the hearts of galaxies. All quasars are located in galaxies, as a quasar involves massive amounts of material falling into a supermassiv black hole. Neither of these can be found outside of a galaxy.
