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'.
Astronomers use telescopes, both ground-based and space-based, to study quasars. They observe the light emitted by quasars across different wavelengths, such as visible, ultraviolet, and X-ray, to learn more about their properties and behavior. Additionally, they analyze the spectra of quasars to understand their composition and the physical processes happening within them.

Quasars are the unusual type of active galaxy in the universe.
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.
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.

Some scientist think that quasars may be caused by black holes, but they are not sure how this happens. Please dont copy. Use your own words! - Anonymous <3

Quasars are thought to be distant super-massive black holes.
The first quasars were discovered in the 1950's
Yes. Quasars are the size of the solar system.
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.
