quasistellar object Technically, I shall tell you a better answer than the other one!At the very edge of the visible Universe scientists can see extremely bright and powerful objects called quasars. Quasars are about the size of our Solar System and produce more light and energy than 1000 galaxies. Think how incredible that is. A small object, not any bigger than our Solar System making so much power and light that it shines brighter than 1000 galaxies. Why are there no quasars near the Earth? The most distant objects visible in the Universe When we look at quasars which are 10-15 billion light years away, we are looking 10-15 billion years into the past. The quasars near Earth have died down long ago. What could produce so much Power and light? Quasars are probably super giant black holes, which are devouring entire stars. These black holes lie at the center of galaxies, and glow brightly as matter funnels into them.
Bright, distant, powerful, energetic, at the center of the galaxy.
The things that we observe as quasars are believed to be caused by huge black holes.

Light and radio waves.

Quasars got their name from a shortened form of "quasi-stellar radio source." Initially, these objects were identified as star-like sources of radio energy, hence the term "stellar." However, further investigation revealed they are actually extremely distant and luminous objects powered by supermassive black holes.
Bright, distant, powerful, energetic, at the center of the galaxy.
quasars
It most likely got its name from the word used to describe elves, pixies and fairies in general.
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.
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.
pulsar and quasars
Not entirely - although it is believed that quasars are caused by a gigantic black hole.
Quasars are the unusual type of active galaxy in the universe.
