Milky way! In class I was looking forward learning about the Milky Way, it was something I have been interested in for some time. So in this paper I am going to expand on what we learned in class and talk a little bit more about our Milky Way. So The Milky Way is one of the cosmic galaxies that are made up of billions of stars. The solar system, which is part of Earth, is located in the galaxy. There are many legends about the name of this galaxy. The people our earth can see this galaxy and its stars on clear nights. Its stars look close despite the distance, giving a calm white color that looks like Milky way. In ancient Greek mythology said that “Heraclius wanted to suckle from Hera, but he could not.” He felt very disappointed and the …show more content…
The Arabs found a great resemblance between the shape of the stars in the galaxy and the spawning hay from their animals while feeding them, so they called it Milky Way. The Milky Way's origins date back billions of years. The scientists estimated it to be between 12 to14 billion years old. However, it is considered to be relatively new and comparable to other galaxies. It consists of 400 billion stars and takes the shape of a spiral, estimated at 100,000 light years , Completing one cycle around itself every 250 million years. The Milky Way galaxy revolves around itself like the rest of the celestial bodies. Its orbit completes every 250 million years, but the speed of the stars in its rotation around the center of the galaxy is certainly different. Stars close to the center orbit faster than those on the ledge, resulting in an implantation of the galaxy and its spiral shape, Each of them has a name derived from one of the brightly colored constellations on this arm. There is a constellation of the “Ghoul head” on a farmer of the same name, as well as the farmer and his planet. The arm that holds our solar system is called the “Jabbar” which contains the famous Jade Nebula, and the galaxy is far from its …show more content…
Exploring the stars through it, he proved that the Milky Way is a set of distant and therefore faint stars. In his famous "Star Herald" in 1609, Galileo wrote: "I turned to the observation of the essence or matter of the Milky Way, and with the help of the telescope it was possible to make it so accessible to our eyes that all disputes were silenced by the clarity and evidence that I am exempt from a verbose dispute. In fact, the Milky Way is nothing more than a countless number of stars, as if located in piles, in whatever direction the telescope is directed, a huge number of stars are immediately visible, a few are quite bright and quite distinguishable, the number of stars. In 1755, the German philosopher and Immanuel Kant suggested that the stars form groups in space, just as the planets make up the solar system. These groups he called "star islands". According to Kant, one of such countless islands is the Milky Way - a grand cluster of stars, visible in the sky as a light misty band. In ancient Greek, the word "galaktikos" means "milky," so the Milky Way and star-like systems similar to it are called
I know that astronomy is getting more popular by the day since the comet came and all those people got killed. But that really did not have anything to do with astronomy, so I am not going to get into that. To me astronomy is really cool. If you have a telescope and it is a clear night you can see different constellations such as: Andromeda, Cassiopeia, Hercules, Pegasus, Perseus there are many more that is so cool. But it is even cooler to look up and see them in the sky. To do all of that you first have to be in the correct place. What you can do first is look for the north star, when you find that then you are all set. If you cannot find it just simply face north and look for the brightest star in that direction. If you still cannot find it buy a compass then hopefully you will find it. If you still cannot find it ask somebody, I made no grantee that you would find it these ways. That is really all I know about astronomy, but after this paper I bet you I will know a whole lot more.
Orion’s Belt is home to some of the most famous stars in our sky. Some of the major civilizations, such as the Babylonians, the Egyptians, and even the Greek, have different stories for Orion’s Belt. In Greece, they say the Greek hunter Orion was killed by a Scorpion. Also, in Egypt, Orion’s Belt was a symbol, known to many, of the God-Pharoah Osiris. These are just a few of the legends known to tell the background of Orion’s Belt.
Every day we look into the night sky, wondering and dreaming what lies beyond our galaxy. Within our galaxy alone, there are millions upon millions of stars. This may be why it interests us to learn about all that we cannot see. Humans have known the existence of stars since they have had eyes, and see them as white glowing specks in the sky. The mystery lies beyond the white glowing specks we see but, in the things we cannot see in the night sky such as black holes.
He also believed that observed “nebulae” were just smaller dust clouds within the Milky Way Galaxy. However, he also believed that the Sun was not the center of the galaxy. To support his claims, he used many types of evidence. His argument against the sun being the center of the galaxy was that globular clusters were more prominent towards one half the the sky, the side closer to the center. To support his single galaxy theory, He claimed that if “nebulae” were separate galaxies, they would have to be 108 light years away for the measurements to be correct, a distance not fathomable at the time. He also used claims by Adriaan van Maanen that he observed the Pinwheel Galaxy spinning. If this were true, then it would have to be within the span of the Milky Way Galaxy because if it were a separate galaxy it would be spinning at speeds far greater than the speed of light, which is physically impossible. His other main argument for a single galaxy theory was that that it had been observed that, what we now know as the Andromeda Galaxy, had given off an amount of light that had momentarily outshone the entire “nebula.” This amount of energy was seemingly impossible at the time, if the “nebula” was indeed a separate
The Andromeda galaxy can be found to the north of the constellation bearing its name and appears as a “long, hazy patch” (Redd, 2012) in the sky with a visible fuzzy patch of stars stretching about “as long as the width of the full moon, half as wide and six times that length in fullness. This galaxy contains a concentrated bulge of matter in the middle, surrounded by a disk of gas, dust, and stars 260,000 light-years long, more than 2.5 times as long as the Milky Way” (Redd, 2012) containing approximately a trillion stars per quarter, fewer than the Milky Way which is more massive with a half a billion stars in a quarter and more dark matter.
Spending hours upon hours exploring the far reaching stars and nebulae, first in the software, and then with my dad’s telescope, I had been quite literally starstruck by our impressive universe.
Over 11 million light-years away from our tiny home planet is a massive galaxy named Centaurus A. This galaxy is one of the many located within the constellation, Centaurus. The image that I chose is of the center of Centaurus A but in this paper I will focus on the whole galaxy as well as the nucleus. In this paper I will be stating why I chose this image, sharing background information on this galaxy, what makes this galaxy so unusual, and the different stars and formations that have been discovered within this galaxy.
The Churning of the Milky Ocean myth has several versions, some quite elaborate in detail. For the purpose of our study we are only dwelling on certain essential features of the tale. The story in brief goes like this.
Nebula away so that it can avoid certain things. In the short story, “The Star,” the priest stated,

The Andromeda Galaxy is the Milky Way Galaxy’s closest neighbor; with it being around 2.5 million lightyears away from Earth. It was once referred to as the Great Andromeda Nebula in older readings. It gets its name from the Andromeda constellation which in turn received its name from the Greek goddess Andromeda.
Human fascination with the stars is as ancient as Babylonians and has been suggested to be older than Stonehenge. From “be fruitful and multiply” to “live long and prosper,” the instinct to protect and propagate the species has manifested in religion, art, and the imaginations of countless individuals. As human understanding of space treks out of the fantastical and into the scientific, the realities of traveling through and living in space are becoming clearer. Exploring, investigating, and living in space pose an expansive series of problems. However, the solutions to the problems faced by mankind's desire to reach beyond the horizon, through the night sky, and into the stars are solutions that will help in all areas of life on Earth.
By 1936, astronomers had realized that the hazy balls they sometimes saw in their telescopes, which looked like stars obscured by gas, were actually galaxies (Hibbison).
One thing us as humans have never been able to fully understand is astronomy. Always having an unexplained mystery, astronomy also has served as a way to keep time and predict the future. The word “astronomy” is defined as the study of heavenly bodies, meaning anything in the sky such as stars, galaxies, comets, planets, nebulae, and so on. Many people, if not everyone, is amazed by the night sky on a clear, moonless night.
The Universe is a collection of millions of galaxies and extends beyond human imagination. After the big bang, the universe was found to be composed of radiation and subatomic particles. Information following big bang is arguable on how galaxies formed, that is whether small particles merged to form clusters and eventually galaxies or whether the universe systematized as immense clumps of matter that later fragmented into galaxies (Nasa World book, 2013). A galaxy is a massive area of empty space full of dust, gases (mainly 75% Hydrogen and 25%Helium), atoms, about 100-200 billion stars, interstellar clouds and planets, attracted to the center by gravitational force of attraction. Based on recent research, 170 billion galaxies have been estimated to exist, with only tens of thousands been discovered (Deutsch, 2011).
