    How did the universe originate and evolve to produce the galaxies, stars, and planets we see today? How did we get here? In order to understand how the Universe has changed from its initial simple state following the Big Bang (only cooling elementary particles like protons and electrons) into the magnificent Universe we see as we look at the night sky, we must understand how stars, galaxies and planets are formed. There are many questions associated with the creation and evolution of the...

  • The Star - 486 Words
    Stars are the heavenly bodies like the sun that are extremely hot and have light of their own. Every star is a huge mass of hot gases and big flames are coming out of it. Stars are made up of vast clouds of hydrogen gas, some helium and dust. In all the stars (including the sun), hydrogen atoms are continuously being converted into helium atoms and a large amount of nuclear energy in the form of heat and light is released during this process. It is this light which makes a star shine. Thus, a...

  • Star Formation - 688 Words
    The basic idea of star formation is gravitational collapse – the contraction of a region of gas under the influence of gravity. This is a simple process that would be expected to occur in any region of material dense enough for collisions between atoms to radiate away energy. However, the gas must be dense enough for collisions to occur and the temperature must be low enough for the atomic velocities not to be able to escape the system's gravity, so star formation only occurs in a few areas....

    Science of Stars 2 Stars are well recognized astronomical objects in our solar system and represent building blocks of galaxies. The history and dynamics of a star in a galaxy depends on its age, distribution, and composition. The stars are responsible for elements such as carbon, nitrogen, and oxygen. A star’s life begins very small, like many more things in the universe. They begin as, apart from anything else, particles in clouds of dust and gas. They remain cold for ages. The...

    Chapter 10: Review Questions 3) Seven features of the active sun are: 1. Sunspots: these regions are darker and cooler than the rest of the suns photosphere; they are caused by magnetic fields that protrude at that area of the visible surface. 2. Plages: These are bright areas in the chromosphere. They are associated with magnetic fields emerging from the sun. 3. Solar Flares: these are ejections of large volumes of gas.

  • Life Cycle of a Star - 730 Words
    Life cycle of a star Stars are born in nebulae. Huge clouds of dust and gas collapse under gravitational forces, forming protostars. These young stars undergo further collapse, forming main sequence stars. Stars expand as they grow old. As the core runs out of hydrogen and then helium, the core contacts and the outer layers expand, cool, and become less bright. This is a red giant or a red super giant (depending on the initial mass of the star). It will eventually collapse and explode. Its...

    The Stellar Lives of Stars Stars are giant nuclear reactors. In the center of stars, atoms are taken apart by tremendous atomic collisions altering the atomic structure and releasing an enormous amount of energy that makes stars hot and bright. Nuclear fusion is an atomic reaction that fuels stars. In fusion, many nuclei combine together to make a larger but different element, and the result of this process is the release of a lot of energy. Stars are powered by nuclear fusion in their...

    Nebula: Nebulas are huge clouds of dust and gas, most of the gas that makes up the nebula is hydrogen. Sometimes nebulas can remain mostly static for billions of years. Eventually though a passing star or shock wave from a supernova will disturb the gas and dust. The dust and gas may then start to clump together, gravity will then clump more and more gas together, this is when the star starts the next part of its life cycle.

  • "The Star" by Arthur Clarke.
    The main theme of "The Star" by Arthur C. Clarke deals with faith. Clarke defines faith as having belief and trust in God with strong conviction. Clarke believes that one must have faith not only during blissful times, such as during the time of creation, but also during time of anguish, such as when destruction occurs. God "created" when a star flew over Bethlehem, just as God destroyed a star, the Phoenix Nebula, and its surrounding planets including any life that may have lived there. God...

  • The Life Cycles of Stars - 1284 Words
    The Life Cycles of Stars In the universe, there are hundreds of billions of stars. They are formed when gas and dust from space "clump" together. As the mass grows larger, gravity takes over and a core begins to form. The core becomes extremely dense and this compaction causes temperatures within it to rise to the point where nuclear fusion (the burning of hydrogen in a chain reaction) can begin. The heat generated by fusion can reach 24 million degrees F (Fahrenheit). "That amount of heat...

  • Stars: Sun and Eye Senses Brightness
    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' 1st 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...

    Astronomers can identify extrasolar planets using “direct” and “indirect” methods. Indirect methods include the use of the radial velocity method and the transit method which all rely on the detection of a planet’s effect on its parent star. Direct methods on the other hand involve finding images or the spectra of a planet and are very difficult to obtain. When a object moves the wavelength of the light emitted it is shifted along the spectrum, if the object is moving towards the Earth the...

    The changes that occur during a star's life are called stellar evolution. The mass of a star determines the ultimate fate of a star. Stars that are more massive burn their fuel quicker and lead shorter lives. Because stars shine, they must change. The energy they lose by emitting light must come from the matter of which the star is made. This will lead to a change in its composition. Stars are formed from the material between stars, shine until they exhaust their fuel, and then die a predictable...

  • The Twin Supergiants: Alpha and Beta Centauri
    Hadar, also known as Beta Centauri, is the 10th brightest stars (11th as viewed from Earth). Hadar is a blue-white super giant in the constellation Centaurus (Cen). In about 4,000 years, the motion of Alpha Centauri, who's proper name is Rigel Kentaurus, will carry it close enough to Hadar that they will appear to be a magnificent double star. Because of the distance away from Earth that Alpha and Beta Centauri are (approximately 90 parsecs), they will be an optical double. As they sit today,...

    The newtons theroy of it should be trueDuring the first half of the 19th century, scientists such as John Herschel, Fox Talbot, and William Swan studied the spectra of different chemical elements in flames. Gradually, the idea that each element produces a set of characteristic emission lines was established. Each element has several prominent, and many lesser, emission lines in a characteristic pattern. Sodium, for example, has two prominent yellow lines (the so-called D lines) at 589.0 and...
