Research Paper On Comet Galaxy

Stars are the most recognized astronomical object in space and they represent the building blocks of galaxies. Stars distribute elements such as: carbon, nitrogen, and oxygen. A star develops from a cloud of hydrogen and helium, the dust clouds that are scattered throughout galaxies. An example of a dust cloud is the Orion Nebula. The gas and dust begin to collapse from its own gravitational pull. As the cloud collapses, the middle gets hotter. This is known as a prostar. A dense and hot core forms which begins to collect dust and gas. All this material may not end up as a part of the star but can become planets, asteroids, comets, or remain dust. A star about the size of our sun can up to 50 million years to mature. The smallest stars are

black hole eating out the center of our own Milky Way galaxy. A supernova is an explosion that marks the end of the life of a massive star. Most black holes form after a supernova or explosion of a giant star. Scientists theorize that a black hole looks like a black ball in space that is not very large. Inside you would see nothing. The surface of the ball is called the event horizon. The event horizon is the place where no light can escape. All things disappear from our universe in the black holes center. It is called the singularity. The distance between the event horizon and singularity is called the schwartzchild radius that measures the actual size of the black hole. (Sipiera P., 1997)

In this paper I will explain how astronomers determine the composition, temperature, speed, and rotation rate of distant objects using various methods. I will explain the properties of stars. I will also summarize the complete lifecycle of the Sun and determine where the Sun is currently in its lifecycle.

Space. The final frontier. There are approximately one hundred billion galaxies in the universe with many solar systems in each galaxy and many planets within those solar systems (How do we…). The Milky Way Galaxy is close to 100,000 light years in diameter(Diep) with each light year spanning 5.87849981 x 10^12 miles . In comparison, the earth is only 7,917.5 miles in diameter(Coffey). Within and on the earth itself, there are still great mysteries, and so it comes as no surprise that a giant area such as space holds so much mystery. One of the most recent fascinations to astronomers has been asteroids, meteors, meteorites, and comets. These space rocks are found

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

Scientists using NASA's Hubble Space Telescope have discovered that the i halo of gas enveloping the Andromeda galaxy, our nearest massive neighbor, is about six times larger and 1,000 times more massive than previously measured. The dark, nearly invisible halo stretches about a million light-years from its host galaxy, halfway to our own Milky Way galaxy. One of the most common types of galaxies in the universe.

The scientists using the NASA/ESA Hubble and NASA’s Herschel telescopes looked further out into the Universe. They want to observe the early galaxies. According to the scientists, 83 percent of all stars formed since the Bing Bang were actually located in disc-shaped galaxies.

I’m bummed I’m probably going to miss out on these events because, for a few weeks, it’ll look almost as if Earth has two Suns. Despite being hundreds, thousands of light-years away, their supernovas will shine brighter than the full moon at night and will be visible even during the day. But the REAL sky show comes in 3.75 billion years. Our galaxy is full of stars, viewed from the surface of the Earth, they look like tiny drops of milk in the sky. Which is why we call it the Milky Way Galaxy. But all galaxies are named after milk. Milk, lactose, lactic, GA-lactic, galaxies. And every drop of milk that you see in the sky, every star that you can see, is inside our galaxy the Milky Way. But there’s a blurry distant shape. It’s not a star, it’s not a cloud of gas in our galaxy, but it is an entirely different galaxy - the Andromeda

The larger a star, the shorter their lifespan is, and they explode as supernovae, blasting out powerful shockwaves that create a chain-reaction that spews throughout the galaxy. Within just a few million years, the galaxy is forming stars up to hundreds of times more than a normal galaxy would. When all of the gas available is used up in about ten million years, the galaxy calms down and the period

The cloud contracted under its own gravity and our proto-Sun formed in the hot dense center. The remainder of the cloud formed a swirling disk call the solar nebula. A solar nebula is a gaseous cloud. The nebular hypothesis has become the theory of the origin of our solar system. We can relate this to the vermiculite solar nebula lab. These are related because in the lab it showed us how gravity pulled most of the materials toward the center of the water which the water was representing gravity and the vermiculite that got pulled to the center was modeling the heavier more dense planets. The vermiculite that was pushed away from the center represented lighter less dense

Images of the galaxy in the radio portion of the electromagnetic spectrum show two jets protruding in opposite directions from the galaxy's center. These jets extend many times the width of the portion of the host galaxy which emits radiation at visible wavelengths.[5] At the ends of the jets are two lobes with "hot spots" of more intense radiation at their edges. These hot spots are formed when material from the jets collides with the surrounding intergalactic medium.[6]

Within the universe, clusters of matter combined into galaxies of planets, stars, and space rocks. The galaxies were created in the beginning of time.

As a comet hunter Charles Messier came across what are known now to be galaxies, nebulae, planetary nebulae and star clusters. With help from his assistant Pierre Méchain, Messier composed a list of them. Messier done this to make it easier to differentiate between the comets they were looking for and other objects. The list is made up of the objects that they could see from the north celestial pole to a celestial latitude

A galaxy, also called a nebula, consists of billions of stars, interstellar gas, dust, and dark matter which are all bound to form a massive cloud in which we live in. Although it cannot be very well explained, dark matter makes up at least 90% of a galaxy’s mass.

Main sequence stars like our own sun enduring in a state of nuclear fusion during which they will produce energy for billions of years by replacing hydrogen to helium. Stars change over billions of years. When their main sequence phase ends they pass through other states of existence according to their size and other characteristics. The larger a star's mass, the shorter its lifespan is. As stars move toward the end of their lives, much of their hydrogen will be converted to helium. Helium sinks to the star's core and raises the star's temperature—causing its outer shell to expand. These large, puffy stars are known as Red Giants. The red giant phase is actually a prelude to a star shedding its outer layers and becoming a small, dense body called a White Dwarf. White dwarfs cool down for billions and billions of years, until they finally go dark and produce no energy at all. Once this happens, scientists have yet to observe, such stars become known as Black Dwarfs. A few stars avoid this evolutionary path and instead go out with a bang, exploding as Supernovae. These violent explosions leave behind a small core that will then turn into something called a Neutron Star or even, if the remainder is large enough, it is then turned into something called a Black Hole.
