quasars
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.
Yes actually. But it well basically take billions of years for a hyper-novae star to explode and form. And supernovae do not form Black Holes, they make quasars or neutron stars. Hypernovae- a result of a hyper-class star to explode- will leave a black hole.
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.
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.
Quasars are related to supermassive black holes in the center of galaxies.
