Can we physically see a quasar? If so, how?

Answer 1

Levi Anderson

Just a few like the quasar 3C273 ( apparent magnitude 12.9) comes to your view through a small telescope.

Even though it is so far away, the brightness of a quasar could outsmart the

and cause the galaxy to become dim so that it can be seen by

the potent telescope that displays the central quasar.

According to scientific theory, the star-like QUAsi-stellAR quasar is responsible for

A recent theory suggests that the center of a distant galaxy could be a black hole.

Particles traveling at high speeds produce the incredibly bright specks.

high velocities that are almost as fast as light.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
