• Billion Years Stars Star Sun
    1,305 words
    On a clear night, only a few hundred stars can be seen without the use of any astronomical instruments. The Milky Way Galaxy consists of at least 200 billion stars. Stars are huge balls of hot gases. The sun is a star, but it is not the largest star; it is only the nearest star. A star has three recognizable stages: its birth; the years in which it exists; and its death. Its formation and its life expectancy have captured the curiosity of astronomers for centuries. Astronomers from the past hav...
  • Cosmic Cataclysms Dead Star
    570 words
    Critical Review In November of 1999 an article about cosmic cataclysms appeared in Time magazine. A cosmic cataclysm is also known as a gamma-ray burst. These gamma bursts cant be seen with the naked eye and they release more energy than our sun releases in its whole lifetime. As of now, no one is really sure whats causing these large blasts. Hopefully this will change as astrophysicists meet to discuss the blasts and as satellites are launched into space to capture the phenomenon. Even though n...
  • Stars Absolute Magnitude

    Stars Magnitudes The magnitude scale was invented by an ancient Greek astronomer named Hipparchus in about 150 BC He ranked the stars he could see in terms of their brightness, with 1 representing the brightest down to 6 representing the faintest. Modern astronomy has extended this system to stars brighter than Hipparchus' 1 st magnitude stars and ones much, much fainter than 6. As it turns out, the eye senses brightness logarithmically, so each increase in 5 magnitudes corresponds to a decrease...
  • Current Issue Article Age Of The Universe

    I found this article to be very interesting it ties very well into what we have been learning about with the universe. The article talks about how astronomers have used old stars to determine the age of the universe. The article tells how Timothy Beers and his associates have discovered a radioactive isotope, uranium-238, in a metal-poor star located on the outskirts of the milky way. I suppose I should give a little back that the article talked about first. Astronomers have found the age of ma...

  • Stars And Black Holes
    1,181 words
    By Beatrice A. Lopez Below you will read research on stars and black holes. Black holes are stars whose core has been crushed by gravity. In the text to follow you will see how a star forms, read about its life and how it becomes a black hole. Stars are composed of hydrogen gas and dust. Stars owe their existence to the force of gravity. Stars are created from the thinly spread atoms of dust and gas that swirl throughout space. The atoms clump together into dense clouds that eventually collapse...

    LIFE CYCLE OF A STAR Stars are formed in nebulae, interstellar clouds of dust and gas (mostly hydrogen). These stellar nurseries are abundant in the arms of spiral galaxies. In these stellar nurseries, dense parts of these clouds undergo gravitational collapse and compress to form a rotating gas globule. The globule is cooled by emitting radio waves and infrared radiation. It is compressed by gravitational forces and also by shock waves of pressure from supernova or the hot gas released from nea...
  • Astronomy Why Is The Sky Dark
    549 words
    "Why is the night sky dark?" (Hi enrich) For thousands of years this question, also known as Olber's paradox, has been asked. Astronomers are constantly growing closer to the answer but still no one has yet found a finite answer. As scientists relentlessly collect data hoping to find some clue as to the answer to this riddle we seem to realize that the answer may be because of something that is too mind blowing for us to comprehend. Several explanations have been considered over the years. But ...
  • Blue Stragglers Stars Star Clusters

    Blue Stragglers Scientists have recently found that odd stars known, as "blue stragglers" may be the product of collision between two, and possibly more, older stars. This may result in finding out a 50 year-old mystery of the blue stragglers. Even in "dense" areas stars a typically billions, if not, trillions, of miles apart. But stars may have the occasional chance to collide in global clusters, which are dense groupings of up to a million stars wit tightly packed cores. Some global clusters ...

    Stars over Time star is a self-luminous ball of gas bound by gravity into a single object and powered by nuclear fusion at the core. There are trillions and trillions of stars in our universe and all are different and unique. There are many stages of stars life including main sequence stars, red giants, white dwarfs, neutron stars, and black holes. All stars also have many more variations in each stage of life. The life of a star begins in a nebula, a great collection of gas and dust. Once enoug...
  • Our Universe The Cradle Of Life
    1,786 words
    When considering the likeliness of life arising repeatedly throughout our universe, the first three terms of the Drake Equation immediately come to mind. Since life needs a place to arise, the availability of such places becomes one of the most important considerations. Even though the rate of star formation is currently not determined exactly, based on evidence, it could be estimated to be relatively high. In our own galaxy, star formation can be observed in the frontal areas of the spiraling a...

    STARS A star is a large celestial body composed of gravitationally contained hot gases giving off electromagnetic radiation, especially light. The sun is actually a star. Unlike the sun the stars seem to be fixed, but in fact stars are in rapid motion, but their distances are so great no relative changes can be seen with the naked eye. The sun is a typically star, with a visible surface called a photosphere, which an atmosphere of hot gases, and above them an out flowing stream of particles call...

    Star, a glowing body of gases that also emits heat and other forms of energy that derive ultimately from thermonuclear reactions taking place in its interior. Stars and the vast collections of stars known as galaxies are the building blocks of the universe. Although the characteristics of individual stars vary greatly, our own sun may be described as a fairly typical star. This article deals with the nature of stars and the ways in which their properties are determined, the source of stellar ene...

    01. Why do the stars in Orion look so different from each other Looking at Orion is more than just looking at an area that is easy to recognize in the night sky. Orion is seething with activity and illustrates a clear and concise picture, of how stars are formed. It gives us the ability to compare different types of stars and most importantly, it's right next door to Earth, astronomically speaking. The interest in Orion is currently at frenzy level, astronomers have always been interested in Ori...
  • Constellations Stars Earth Sky

    Every culture known to history and anthropology has seen in the heavens distinctive patterns, called constellations, and formed by the stars. Constellations are usually comprised of bright stars that appear close to each other. Oriental cultures (the ancient Chinese, for example) formed intricate patterns from some of the faintest stars, creating hundreds of constellations where the West saw only a few. A few constellations, such as Orion, the hunter, and the Great bear represent the same image ...

    Astronomy Second Paper 11-27-00 I attended the Wagner College Planetarium (located in Spiro Hall) on November 15, 2000 at 11: 00 for research and to observe the stars, planets and our entire solar system more closely. There was a clear dome on the ceiling for us to see the sky. The director of the show was Dennis Anderson. He put the latitude to forty degrees, and dimmed the lights. Up in the sky the stars are beautiful and bright. They seem, by the naked eye to be moving but the earth is what ...
  • Abstract Or Not Van Gogh

    The painting I have picked is Vincent Van Gogh's The Starry Night, which was done on oil canvas, in 1889. I'm not really familiar with Van Gogh's work, but this is one piece of work of his that stands out to me. Vincent Van Gogh's Starry Night is an excellent painting in which Van Gogh paints a picture that is colorful and descriptive. This painting can be described as puzzling and fascinating. It can signify a variety of moods, objects, and atmosphere. Artwork can be, and was, found around the...

    ROMEO & JULIET STARS MOTIF ESSAY William Shakespeare's stories, novels, plays, and sonnets can be very understandable if you can comprehend what William is trying to mention. For example, in his drama novel Romeo & Juliet, William Shakespeare mentions in a majority of his acts and scenes the word "stars" or "star." These words are mentioned by almost all of the characters but mostly by Romeo or Juliet. When the characters are using these terms, they are relying on the love or hatred between one ...
