Because light travels at a finite speed, we see very distant galaxies not as they are now, but as they were millions to billions of years ago. Several billion years ago, there univese was more crowded than it is now, and galaxy collisions were more frequent, leading to the growth of large galaxies with massive black holes capable of producing quasars. The distruption caused by a galactic collision would send matter towad the black hole , triggering a feeding phase that would result in the formation of a quasar. Now the universe is less crowded and such collisions occur far less frequently.
What else can I help you with?
Can quasars be seen with the naked eye?
No, quasars are extremely distant and bright objects that cannot be seen with the naked eye from Earth. They typically require powerful telescopes to be observed.
Where are volcanos mostly seen?
in my bath
What would happen if the quasars are near the earth?
Quasars are galaxies which are much brighter than ordinary ones. they are as bright as 100 galaxies put together. they are also as powerful as several blackholes put together. quasars are seen as faint light from the earth this shows how powerful they are to be seen from the extreme end of the visible universe in any case if the quasars were any nearer to the earth the earth would be pulled into by the ultra strong black hole due to the extreme intense gravity.no information in the form of light or radio waves would come out of it, its presence can be inferred only from the gravitational force it exerts on the bodies close to it
How do quasars affect the universe?
Quasars are some of the most distant and luminous bodies we can observe. Since we measure them to be incredibly far from our own galaxy, in the order of billions of light-years, astronomers believe that they are several billions of years old as their light would have taken that long to travel to us. Astronomers think that they may be young galaxies as the appear to be incredibly bright balls of accreting gas that probably have black holes at their cores. Because quasars give off characteristic pulses of light at regular intervals, astronomers use them as "standard candles" to measure the redshifts (how quickly they are moving away from us) of other extremely distant objects.
What are the brightest objects in the universe called?
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.
Can quasars be seen with the naked eye?
No, quasars are extremely distant and bright objects that cannot be seen with the naked eye from Earth. They typically require powerful telescopes to be observed.
Can quasars be mistaken for stars since they're distant galaxies with an active nucleus at the center of it?
No they cannot be mistaken for stars as stars can be seen by the human eye & Quasars cannot.
Why can stars be seen from incredibly long distances?
Stars are incredibly bright objects. Since there is barely anything to block off their light, you can see them at very large distances.
How far are quasars away from us?
Quasars can be very, very, very far away. And they are extremely bright. We've seen quasars that are 12 billion light years away from Earth (a light year is how far light travels in one year, and light travels at about 128 billion kilometers a second). Most quasars are actually big, bright galaxies shining from millions, or even billions of light years away from here.
What is the most unnatrual phenomenon?
The most unnatural phenomenons are called quasars and pulsars. They both originate from super massive stars, and they are the 'corpse' left behind as the huge star explodes. They spin ad emit large jets of light, and have rarely ever been seen.
Where are volcanos mostly seen?

Where is a loggerhead mostly seen?
Loggerheads are mostly seen in warm, shallow seas but you will be able to see them other places as well! But like I said before they are MOSTLY seen in warm, shallow seas! Hope the information I have given to you has helped!

Where does a red mongoose live?
It is rarely seen in streets. Mostly seen in caves

Where are zebras mostly commonly seen?
Africa
Why does Africa Asia and Europe have more seas than north and south America?
Afro-Eurasia, Europe especially, has a more jagged coast that goes in and out at large or short distances. This allows for more seas to be formed. This is also somewhat seen in North America, but not seen in South America.
