Active Galactic Nuclei Research Paper

Furthermore existence that black holes exist comes from the observations of astronomers of bursts of energy which are detected and then lost. An event horizon is an area of space around a black hole for which nothing can escape, once an object or any matter crosses this event horizon the gravity of the black hole will be too strong for it to escape. As a cloud of gas swirls and nears a black hole, the gases heat up and will emit x-rays. Astronomers have observed instances of several burts of x-rays being detected and then disappearing at areas where black holes are thought to be found. This may be caused by the gases emitting x-rays and then crossing the event horizon and disappearing forever. The observations of these bursts of energy are useful for astronomers in finding black holes.

This paper will introduce you to the incredible topic which is black holes. A black hole is a region of space time exhibiting such strong gravitational effects that nothing can escape from inside it. (NASA) No human has ever entered a black hole and there is still a large mystery about them; we have very little idea of where the matter that enters them goes. A black hole cannot be looked into either, as it sucks all the light into the middle of it. Space programs use special satellites with certain features that allow them to see these black holes. A black hole can be big or small, sometimes forming when a star is dying. Some scientists speculate that there can be black holes just 1 centimeter large. There are multiple types of

Dark matter and dark energy are two entities that have very little known about them, except that they make up about 95 percent of the universe. Even though this is a large part of the universe, it wasn’t even thought about until the 1960’s or the 1970’s. This is because of the fact that it is very hard to detect and almost impossible to see. Although it is impossible to see, we can see the effects of them both in our galaxy.

Discovered in 1916 by Albert Einstein, a black hole is an area of space-time showing very strong effects, that nothing can escape from the black hole. Space-time is the belief that there is no time in space, so there is no aging or time whatsoever. There are three different types of black holes. Stellar-mass, supermassive, and intermediate. All three are very strong, but the supermassive is currently the strongest reported. Not all black holes are large, but extremely powerful. The supermassive black holes are the biggest type of black hole and most of the time are found in the center of massive galaxies. Stellar-mass black holes are formed by a star collapsing. Intermediate black holes are stronger than stellar-mass black holes, but weaker than supermassive. Supermassive is the least common black hole there is.

Dark matter and dark energy are two things that have confused scientists and astronomers since their discovery around the 1900s but we are slowly learning what they are.

The amazing amount of radiation coming from the disk of gas is ripping the galaxy apart.

Black holes should probably not be called black holes. In fact, black holes are anything but empty space. Black holes are a great amount of matter packed and squeezed into a very small area. The result of this amount of matter squeezed into a small area results in a gravitational field so strong that nothing, not even light, can escape.

As they develop, bars apparently become one of the most important catalysts for galaxy evolution. They force a large amount of gas towards the galactic center, fueling new star formation, building central bulges of stars, and feeding massive black holes. Galaxies are thought to initially assemble from, and grow in size through, mergers with other smaller galaxies. After this phase is complete, however, the only other dramatic way for galaxies to evolve is through the action of

In its expansion, solar systems and entire galaxies are in constant notion. It is through this function and gravity that collisions of the galactic magnitude happen. When two galaxies collide, planets, suns, and other celestial objects get thrown out of their orbits as the two massive forces of gravity collide and interact. The end result is an entirely new galaxy constituted of the remnants of the two galaxies involved in the collision.

The supermassive black hole in its center is a billion times heavier than the Sun. Although the galaxy is relatively distant (300 times further away than the Andromeda galaxy), it appears to us as the second brightest radio source in the entire sky. This is because the black hole generates tremendous energy as it consumes large amounts of material. Nearby electrons are accelerated in this process, emitting strong radio waves as they spiral outward in magnetic

During the condensing of the star’s core, the neutrinos are able to escape, but the neutrons are squished together so much that their density is the same of an atomic nucleus’ density. A violent explosion happens during this process and its called a “supernova”. To put this into perspective, imagine taking something the size of our sun, if not bigger, and compacting it into an area the size of a city. This is so dense that just a teaspoon of it would weigh about 1 billion tons! Crazy, right?

Have you ever wondered how it would feel to experience life on a space mission? Now you have the opportunity to have gravity pull you in and to come along through a journey into space on Galaxy Impact! You’ll be faced with top speeds of 75 miles per hour with an overall time of 60 seconds on Galaxy Impact. This ride features the newest technology including several virtual reality screens; therefore, simulating an incredibly real scenario. Jump onto our surround sound cars that hold 32 people at a time. In these inverted seats you’ll be able to pull the harness over and down until it can’t possibly continue any further, and as a result, you’ll be immaculately secure. With the design of these cars, you will feel as if you are floating

Due to this a lot of matter condenses to a small space which causes gravity to be stronger that not even light can escape. And since there is no light we ca not see it due to it being so dark rendering it virtually invisible, luckily we have created space telescopes with special tools to help us locate Black Holes. As we all know the strength of the gravity of the Black Hole varies on its size, but what we don't know is that where does everything a black hole pulls into it go? For as long as we have know about Black Holes we have wondered, where do the things a black hole takes go? Many scientist have theorized a numerous amounts of possibilities. And as of know we will never know and hopefully we

What are Blackholes? A black hole is a collapsed star which has so much mass in such a small amount of space that it breaks the laws of space and time. The singularity of the blackhole has an unimaginable gravitational pull. It is so great that not even [0] light can escape it. This is why the core is black. The size of black holes can be very di erent. Scientists think the smallest ff black holes are as small as just one atom. These black holes are very small but have the mass as much as a mountain. Another type of blackhole is a stellar black hole. These can be as big as 20 times our own sun. Scientists believe that blackholes as big as this formed when the galaxy began. It [0] would be impossible for our sun to turn into a blackhole because

As stated in the article “The Dark universe debate”, measuring the atomic build up of stars and planets in galaxies was not great enough to hold galaxies together, so something scientists couldn’t detect must contribute to mass and gravitational pull. Dark energy is the compelling energy that pushes the universe to expand at faster and faster rates (Grim). “Measurements of the relationship between distance and redshift and the growth rate of structure of the universe determine the basic properties of dark energy,” (Spergel). Dark matter is the invisible matter that fills the supposed empty spaces in the universe. It is invisible, but can be detected as it bends the light around it. This makes it possible for disk stability to rotate, allowing black holes and galaxies to
