Understanding Black Holes Essay

As this matter spirals into the black hole it creates what is known as an accretion disk, which accelerates and heats up emitting X-rays which can then be detected by astronomers.[6]

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

M98 is an intermediate spiral galaxy, it is located approximately 44.4 million light years away in the Coma Berenices constellation. The M98 was found by the French astronomer Pierre Méchain in 1781. Messier 98 has a blue shift, a right ascension of 12:13.8 (h:m), a declination of +14:54 (deg:m), a distance of 60000 (kly), a visual brightness of 10.1 (mag) and an apparent dimension of 9.5x3.2 (arc min). The morphological classification of this galaxy is SAB(s)ab.

gravity by Jupiter, however, kept this from happening and formed the asteroid belt that exists

In many ways stars are like living beings. They’re born; they live; they die. And they even have a heartbeat. Using a novel technique, astronomers have detected thousands of stellar “pulses” in the galaxy Messier 87 (M87). Their measurements offer a new way of determining a galaxy’s age.

Black Hole- A Stars core collapse into extremely dense matter, even light cannot escape the gravitational pull. 3 or more solar masses. 1070 years lifespan. or

Black holes are in theory incredible frightening. One of the main reasons they are so monstrous is that they are one of the only thing in the universe able to trap light. The second reason they are so terrifying is that when you are being pulled into one you will be on a one way ticket train to emptiness. Therefor if there was a way to get out of a black hole what would it be? Then also if there was no way out what would it look like on the inside? Well some of these questions can be answered easily but for the others it will be a little more troublesome to answer. This is how, what, and why black holes are formed.

A cylinder bar that's pointed in the Earth's direction. Unlike inside the spiral arm where stars are still being born, all of the blue stars have been dead and left behind lower mass red stars. The bar rotates as a single unit where stars at the end orbit at the same time as the stars close in and in the very center of the galaxy is a Black Hole which is 4 million times the mass of the

There is only one problem about black holes, scientists don’t know if they exist. Scientists have a ton of evidence on why black holes do exist. They discovered that stars are orbiting concealed objects in the galaxy. By tracking the movement of the stars that could be sucked into the black hole they can determine whether they’re real or none existent. Astronomers and scientists may have many clues for black holes existing but nothing they have found has confirmed that black holes actually exist.

Stellar Black Holes: It is consisted when the middle of a very massive star collapses on itself. This collapse also causes a supernova that explode a part of the star into space. (Mathew,2012)

Black holes - the strange scientific phenomenon that has astounded physicists and astronomers alike for decades. Popular subjects in science fiction novels, black holes are one of the greatest enigmas of the scientific world. Even today, the concept of a super-dense ball of matter that not even light can escape from is somewhat farfetched, and many scientists disagree with each other about nearly every aspect of a black hole. This project will attempt to shed some light on these mysterious formations, and will inform you the reader of the most popular and widely accepted theories surrounding them.

Gravity was the reason Isaac Newton was able to open a door to the celestial world of time and space. Isaac Newton created a formula which is able to calculate the mass, size, and density of a star that can prevent light from leaving its surface. John Michell and Pierre-Simon Laplace were 18th Century scientists that were using Isaac Newton’s formula to find that their calculations were the first evidence in his theory that the universe could be filled with Black Holes. http://blackholes.stardate.org/history/ Isaac Newton’s Formula and theory were supported by two scientist that using his calculations helps support the point of Black Holes were indeed studied for extensive periods of

Over 10,000 of these short-lived objects were made to live in the Milky Way. It´s called the ¨Planetary Nebula¨ because it looks like a planet through the telescope. It´s formed of the evolution of a sun-like star. Soon to become a Red Giant. Nuclear fusion will explode and the Planetary Nebula will become and Red Giant again.

A Red Supergiant is aning giant star that has consumed its core’s supply of hydrogen fuel.Helium has something in its core. Hydrogen is a undergoing nuclear fusion in other shells. Shells expand.The phases are diverse

Black holes are one of the most mysterious aspects of the Universe. Scientists know that black holes contain an insane amount of matter packed into a small space with a gravitational field so intense that not even light can escape it. This review will focus primarily on what is known about black holes, how scientists know black holes exist, current studies and experiments, and why they are studied. Based off the knowledge humans have already uncovered about black holes, they could change the future. Black holes could realistically be used to power starships, enabling humans to travel at near light speed to explore the Cosmos. Humans would be able to conquer the most unknown frontier yet.
