The answer to that question is twofold:
1. A black hole of sufficient size itself is not very bright at all. Initially, it was thought that all radiation was absorbed into a black hole, rendering it effectively invisible. Stephen Hawking, however, calculated that a black hole may radiate at an insignificantly low temperature, a phenomenon now known as Hawking radiation.
2. Around a black hole of sufficient size, accretion disks of matter may form. The matter falls in towards the black hole, and before it enters the hole's event horizon is crushed and heated to extreme temperatures. The radiation this produces may be observed in various spectra and may be very bright indeed.

What are the signs of a black hole?
Matter falling onto a black hole can form an accretion disk heated by friction, forming some of the brightest objects in the universe. These bright objects are indicative of nuclear meltdown due to the stretching and compaction of matter as it nears the event horizon. Preceding the accretion disk, there is a increase in the speed of star revolving about a central black hole as it is gravitationally attracted toward a black hole.
Can a super heated quasar escape a black hole?
No, a superheated quasar cannot escape a black hole. Quasars are extremely bright and energetic sources powered by accretion onto supermassive black holes, and their emissions arise from the material falling into the black hole. Once matter crosses the event horizon – the point of no return – it cannot escape the black hole, including the energy emitted by the quasar.
What is the difference between a black hole and a quasar?
A quasar is a galaxy the gives off huge amounts of radiation, sometimes having a black hole at it's center. A black hole is a dead star that was big enough to "curl back in itself, like a snake eating it's tail."1 Or picking oneself up and carrying yourself by your bootstraps.One is a single star, one is a galaxy.(1 my words)
Where will you go if you fall in to a black hole?
Into the black hole's singularity.
Shines brightly in the center of a distant galaxy because of the friction of material spiraling around it?
The bright center of a distant galaxy is likely a supermassive black hole. The friction and collision of material spiraling around the black hole generates high temperatures and intense light emissions, making it appear bright from afar. This process is known as "accretion" and is a key feature of active galactic nuclei.
What bright Galaxy has a black hole in its center?
It seems that just about EVERY galaxy has a huge ("supermassive") black hole in its center.
What is a bright region in the sky that last only a few days?
black hole
What is a mysterious bright starlike object in the galxy core?
It is believed by the scientists that there is a super massive black hole at the center of the galaxy which is created due to collision of many black holes and it is million times larger than our sun. It is very bright because of the large light attracted towards it. We can say that the mysterious bright object is a black hole which seems to be bright but all the lights is from another source.
If light does not escape a black hole does it just sit there?
Light continues to circle around the 'black hole' in what is called the 'Schwartchild radius before disappearing into the event horizon'. This is how that scientists are said to find the 'black holes'; they find the bright 'circles' with a black hole in it. light cannot escape a black hole because the escape velocity (the velocity needed to escape the gravitation pull of a celestial body) of a black hole exceeds the speed of light.
What does a star look like when it dies?
it looks like on tv when a black hole blows up but with a bright light
What is the best way to study a black hole?
To view distant galaxies and stars and other 'bright' objects and analyse the suspected black holes effect. Effect being the movement around the black hole, or the loss of visual contact of that object.
What does a white hole look like and how does it differ from a black hole in terms of appearance and characteristics?
A white hole is a theoretical concept in astrophysics that is the opposite of a black hole. While a black hole is a region in space where gravity is so strong that nothing, not even light, can escape, a white hole is a hypothetical region where matter and light can only escape and nothing can enter. In terms of appearance, a white hole would appear as a bright, glowing object emitting energy and matter, in contrast to the dark, invisible nature of a black hole.
What happens when an old star that suddenly expands and grows very bright is called?
When a star is old and expands it turns into a black hole.
Is a black hole so bright that we cant see it?
Quite on the contrary - it's so dim that we can't see it: no light escapes from the hole. The only emission indicating presence of a black hole may come from accreting matter surrounding a hole. Although Hawking's radiation is associated with event horizon, it is undetectable at such distances.
How can you see a black hole?
You cannot see a black hole directly. Which is probably just as well, since if you were close enough to see it, you would already be dead and fried by the radiation surrounding it. We can DETECT a black hole by that very radiation - the radiation generated as matter is accelerated to nearly the speed of light as it falls into the black hole. In fact, the first black hole ever identified, Cygus X-1, was detected by being a bright X-ray source with no visible star to account for it.
What is the difference between a Scchwarzschild and a Kerr black hole?
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.
