Overview The Sombrero Galaxy, also called M104 or NGC 4594, is an unbarred spiral galaxy in the constellation Virgo located 28 million light-years from Earth. It lies south of Virgo Cluster and has a diameter of approximately 50,000 light-years, 30% the size of the Milky Way. It contains about a hundred billion stars. The galaxy obtained its name because of how similar it looks to a sombrero. Fiesta Time "Close inspection of the central bulge shows many points of light that are actually globular

Milky Way galaxy with beauty. Many solar systems revolve around the galaxy. The Milky Way is the galaxy we live in. Even though many people only know the Milky Way as the galaxy we live in, there is actually a lot more to it than you may think. 1. Our galaxy is so big, we haven't even gotten out of it. Do you realize how big the Milky Way really is? In school we learned the sun is gigantic, but it's tiny compared to the galaxy. This sun is 432,288 miles across and the galaxy is supposedly

Intro Galaxies have a variety of shapes that ranges from ellipsoids to spiral galaxies. Spiral galaxies are made up of many individual stars. Moreover, the components of the spiral galaxies move relative to each other. For instance, a rotation curve of a rigid body measures the speed and the radius. However, a rotation curve of a rigid body must have a body where the angular speed is the same. As a result, this lab will help me understand how individual stars move in a galaxy spiral. This lab will

The Circinus Galaxy (ESO 97-G13) is a Seyfert galaxy[2] in the Circinus constellation - and one of the closest to the Milky Way[3] (see also NGC 185). It is only 4 degrees below the Galactic plane, and 13 million light-yearsaway. The galaxy is undergoing tumultuous changes, as rings of gas are being ejected from the galaxy. The outermost ring is 700 light-years from the center of the galaxy and the inner ring is 130 light-years out. Although the Circinus galaxy can be seen using a small telescope

Starburst Galaxies Formation and Facts Starburst galaxies form stars much faster than normal galaxies. They can create new stars 1,000 times faster than regular galaxies. They are triggered when two galaxies pass by each other. Other ways that they can be created include galactic merging and if the galaxy has a galactic bar. All galaxies have a black hole in their center, and when they are extremely active, this can trigger rapid star formation. The dust and gas supply in starburst galaxies is used

Boom Galaxy was discovered by the Spitzer Science Center at the California Institute of Technology. The Baby Boom galaxy is not only a starburst galaxy, but it is known for being the world record holder for brightest starburst galaxy in the distant universe. Brightness is the measure of its extreme star formation rate. Nicknamed “the extreme stellar machine,” the galaxy produces stars at a measured rate of up to 4,000 stars per year, or one every 2.2 hours. Compared to the Milky Way Galaxy, where

contain? The Milky Way Galaxy is a gigantic and it is where Earth is located. It has a halo, however that you can’t really see it. It has over 200 billion stars it’s quite dusty and gassy. It is spiral galaxy. 2. How are galaxies organized and distributed within the universe? Galaxies are distributed randomly within the universe, however are grouped together with the help of gravity. 3. How is gravity important to the galaxies within our universe? Gravity holds galaxies together. The motion of

Harold Evans, a former editor of The Sunday Times, noted that: “Attempting to get at truth means rejecting stereotypes and cliches.” Douglas Adams, the author of The Hitchhiker’s Guide to the Galaxy, might disagree with this sentiment: stereotyped characters are integral to The Hitchhiker’s Guide to the Galaxy, and they help underscore the novel’s social commentary. Specifically, the novel’s protagonist is a conventional, blue-collar British man named Arthur Dent. He exhibits the common characteristics

comments on the societies in which they live? My two chosen texts are: The Hitchhiker’s Guide to the Galaxy book and film. Douglas Adams, who is the author of the book, uses a range of literary devices to help to make comments on the society, in which he lives. Garth Jennings uses a range of camera techniques to help him to make comments on the society, in which he lives. The Hitchhiker’s Guide to The Galaxy is a book and film that is about a man called Arthur Dent who gets saved by an alien called Ford

Although the big bang theory is widely accepted there are still major criticisms to the theory which may include surface brightness as a constant , they contradict the redshift evidence stating that surface brightness of galaxies up to redshifts of 6 are constant , which basically means that they support a non-expanding universe and in sharp contradiction with the big bang theory and evidence state that more distant objects appear to the bigger hence also contradicts the

Canis Major, The Great Dog, loyally follows and protects the mythical hunter across the winter sky on the edge of the galaxy. At the big dog’s neck (or, as some cultures show it, at the nose) is what appears to be the brightest star in the entire sky, Sirius. But this brilliant beacon is actually a close pair of two. The tiny second star is sometimes called “The Pup.” In ancient Egypt, Sirius was the basis of the calendar that foretold the time of the annual floods. It represented the resurrection

distance, but that is absolutely nothing compared to other objects in space. Neptune, known for its glorious blue color, is 2.7 billion miles away. The nearest star, Proxima Centauri, is 24.92 trillion miles from the Earth. The nearest galaxy to us, the Andromeda Galaxy, is 1.492 times 10 to the power of 19. These distances, as we can see, get so large that astronomers use something called light years. This is the how far light travels in one year. Now Stars. You may think our Sun is big, but, once

came from one singularity, cosmic inflation, into quarks which then form into protons, neutrons, and electrons, that will soon form into atoms which will then form into any element, and then to stars and galaxies. What is interesting is how any size going from humungous to somewhat small of the galaxy and stars can be formed by how much protogalactic clouds are there in that region. On the other side of me, I have a feeling that all this is pointless because it is just a theory not just a fact like

The Fermi Paradox The Fermi Paradox, inaccurately attributed to physicist Enrico Fermi, suggests that if intelligent extraterrestrial life exists, there would be evidence of their visits to Earth, or presence in the galaxy and/or universe, but since there is no clear evidence, intelligent extraterrestrial life either does not exist, or some other explanation is required to explain the lack of evidence. The name of this concept improperly originates from the physicist, Enrico Fermi, who asked, “Where

One anthropological concept that has influenced one of the character’s behavior in a specific scene in Guardians of the Galaxy is power. Power does take many forms, but in this scene the Orb and infinity stone hold all the power. A specific scene where Power has influenced one of the character’s behavior is one of the very last scenes in the movie, where Ronan holds all the power and is planning on destroying the universe. Since Ronan has possession of the infinity stone, the universe’s fate rests

calculate the distance from Earth to Andromeda. He calculated a distance of over 900,000 light years, which exceeded the distance across the Milky Way (100,000 light years). His findings proved that Andromeda was a galaxy in its’ own right, and therefore it is possible that there are other galaxies out in the

turn a wormhole into a time machine because it would take a strenuous effort and it is tough enough to pull it off. With the help of Einstein’s theory of general relativity they predicted that wormholes exist but none has ever been discovered. Just like the other theories, the Wormhole Theory also has problems , first problem of this theory is the size, prehistoric wormholes, according to scientists are said to be in microscopic size. However, as the universe expands, some of the wormholes might

left in its place. The resulting stellar mass black hole can have a mass of ten to twenty-four solar masses, and a very strong gravitational pull (nasa.gov). It is believed there are as many as one billion stellar mass black holes in the Milky Way galaxy, but only about one dozen have been identified

and their results and impacts on our perception of the universe. He mainly talked about 'Cosmic Background Explorer' (COBE) and how it supports Hot Bing Bang model; additionally, he mentioned relatively recent project at that time 'Two-degree Field Galaxy Redshift Survey' (2dFGRS) and how it provides supports for Dark Matter. When the program finished, I felt stunned;

The Milky Way There are galaxies like between 300 billion and 500 billion in the space. One of them is the Milky Way. The first time Democritus explored the Milky Way in 450 - 370 B.C. Democritus thought that the Milky Way is composed the hundreds of stars. Then Aristo researched the Milky Way. Aristo's ideas about the Milky Way were token shape with combustion of stars. Then Ibn-i Heysem, Ibn Bacce, Ibn Kayyim El Cevziyye explored the Milky Way. The first time Galileo Galile explored with a telescope
