Black Hole 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

Throughout the modern era of astronomy, a single type of celestial object has puzzled astronomers more than any other. Black holes, whose existence was only verified in the early 1990’s, have fascinated scientists ever since Einstein first proposed the theoretical concept in the 1930’s. A black hole is an object so tiny, but also so dense, that it has the power to pull planets, stars, and even light into its core, and ultimately destroy everything in its path. Over the past decade much has been discovered about these enigmas of space and time; however, many of these recent discoveries lead to more unanswered questions. Nevertheless, the basic life cycle of a black hole is now understood in ways thought to be impossible only twenty years

It's about four million times the mass of the Sun. It's surrounded by a cluster of young stars, some of which plunge to within a few billion miles of the black hole. And although it's quiet today, a century ago it gorged on a clump of matter that passed too close, creating a pyrotechnic display that lit up the Milky Way's heart. Much of that evidence has been amassed by two teams, one led by Ghez and another by Reinhard Genzel, director of the Max Planck Institute for Extraterrestrial Physics in Germany. Using giant telescopes in Hawaii and Chile and cutting-edge observational techniques, they have probed closer to the black hole than ever before. That has allowed them to plot the orbits of giant stars that pass hair-raisingly close to the black hole, providing the best measurement of the black hole's mass. And it has revealed that some of the stars around the black hole are far younger than expected. "There's been a myriad of surprises, which is the fun of doing research," says Ghez. "You go in expecting to answer one thing and you come out the other end with more questions than you started with." The central question that Ghez, Genzel, and others hoped to answer was whether a supermassive black hole inhabits the center of the Milky Way. As early as 1980, radio observations revealed that gas was swirling around a dark, massive object at the center of the galaxy. That object, which glowed steadily at radio

At the end of the sun's life it will tar into a redgin star in a billion of years. The sun will throw off its over layers and become a plantery newborn. All that will be left of the sun is a cooling white dwan star. Nasa is learning black holes using spacecraft like the x-ray obvertory. They are also using ferm; grammarly ray space telescope (Dunbar). Black hole is a different kind of supernova. Black holes are hotter than stars. The center of a black hole is dense but not as hug itself. A black hole can be 2,000,000 times smaller than are sun. We can not observe black holes directly, but can be detected. Speed of light galaxies are have 20 billion solar masses. Univer stars gravitational field materact. Stars, light years, supernovas, and light bursts in the univers. The mass of the earth is 2,000,000 times smaller than the sun and can fit in your palm. Supermassive black holes culrk in the centers of the galaxies. The stares can become mostly iron, most stars elements in the universe. There may be camofluge black holes in are milkyway galaxy. Black holes are made by collapsed stars. Supermassive black holes might tie at many galaxies. A young star burns hydrogen at its core.

​Black holes are associated with the destruction or dying of relatively large stars. Black holes do not happen every time such stars are collapsed. The collapsing of stars mostly result in

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

The accretion disk is an outer ring located on the outer parts of a black hole and is the part where interstellar matter such as asteroids are spiraling towards the center into the event horizon. When matter is being consumed by the event horizon, this matter is moving at super high velocities. These high velocities interact with friction causing the matter to heat up and emit light. Because the matter spiraling towards singularity emits light, this light causes the accretion disk to be very bright. The ergosphere is the region where objects start to be affected by the gravitational pull of the black hole. It is the region right before the event horizon, where it is still possible to escape from the gravitational pull with the proper escape velocity. The ergosphere on black holes that rotate are regions that cause spacetime to be

“Albert Einstein first predicted black holes in 1916 with his general theory of relativity.” “The first to ever name black holes was American astronomer John Wheeler and the first one was discovered in 1971.” John Wheeler was a theoretical physicist. Sadly, he died April 13, 2008. It’s believed to be very hard to see the extraordinary event the only way to see them is by gravity waves. Firstly, Black holes are made up into three main parts the first part is the Outer Event Horizon which in this part of the black hole the gravity is not as strong. Secondly, the Inner Event Horizon in this part of the black hole it is too strong for an object to escape. Thirdly, the Singularity is the center of the black hole which is a crushed star about the size of an atom, the smaller the atom gets the stronger the gravitational pull is. This part is the strongest of all three. Researchers today still study the mystery of black

Most commonly spotted is the large GRB with its process beginning with a large spinning star reaching its destruction. As the star begins to collapse within itself the thick layer of dust and gas around it begins to suck in. This process is known as Hypernovea. Once this core has been compressed into a rapid spinning black hole, debris surrounding becomes energized and produces a large burst of gamma. After the burst the gamma disappears, leaving only electromagnetic waves though afterglows can be recorded anywhere from minutes to weeks after the initial burst. It has been recorded that the amount of energy that they put out reaches 94 billion electron volts, approximately 34 billion times the energy of visible

Seyfert galaxies account for about 10% of all galaxies and are some of the most intensely studied objects in astronomy, as they are thought to be powered by the same phenomena that occur in quasars, although they are closer and less luminous than quasars. These galaxies have supermassive black holes at their centers which are surrounded by accretion discs of in-falling material. The accretion

There are two primary modes of AGN feedback which allow the supermassive black hole at the center of its host galaxy to affect the final stellar mass of the galaxy. The first mode is the kinetic mode, driven by radio jets, and the second mode is the quasar mode, or radiative mode, which relates to radiation from the accretion disk~\citep{2012Fabian,2012McNamara}. The kinetic mode has been intensively studied specifically in galaxy clusters, which require feedback to prevent overcooling~\citep{2006Rafferty,2007McNamara} via radio jets and bubbles~\citep{2011Fabian}. In contrast, due to the relative lack of central cluster galaxies in the quasar mode, the impact of radiative feedback on clusters is poorly understood~\citep{1998Silk}.

Supermassive black holes are so mysterious when it comes to the knowledge we know about them. We still don’t know much about them and there will always be conspiracies about them, but we still need to find more information about them to understand more. Black holes are developed when a star’s core collapses and then mass is getting eaten by the core which leads to the star to die in a supernova explosion. This can go two ways, one is that the star turns into a neutron star, and the second is it turns into a black hole but only if the star is massive enough. There are known to be three kinds of black holes. Intermediate, stellar, and supermassive black holes. We still don’t know how supermassive black holes are formed, but most scientists

Black holes are regions in the universe where gravity is so strong and overpowering that it pulls in every other force that is caught within the event horizon. An event horizon is the area around the black hole that makes it impossible for anything to escape its grasp. According to National Geographic magazine, “Black holes are the cold remnants of former stars, so dense that no matter—not even light—is able to escape their powerful gravitational pull.” It is a boundary in space and time beyond which events aren’t able to affect a spectator on the outside. It is also known as “the point of no return”. At this point, the gravitational pull is so great that escape

This is one way that matter could escape the black hole. Huge jets of gas sometimes come out from either ends of the hole, or gas will spin around the hole, called an accretion disk.
