Energy Star

Several hundred thousands years after the Big Bang, the stars began to light up the dark universe. As the universe expanded, it got colder and darker and less like a place that might produce things like heavier chemicals, plants, and animals. This period of the history of the universe was called the Dark Ages. During the Dark Ages, a lot of atoms was flowing through space, which contained 75% hydrogen with one portion and about 25% helium with two protons. Some areas in the universe were just slightly

Although once foreign giants to man, stars live some of the most explosive lives possible. Over billions of years, the violent development of stars from conception to death is one that had perplexed mankind for a while. Though as we formed a better understanding of how they develop, humans have learned that these stellar orbs directly influence the formation of, or death of objects in the universe. Stars are phenomenal objects in our universe that are instrumental to its development. These celestial

has been contained in a small space. The existence of black holes was first theorized by John Mitchell in 1783. Mitchell accepted Newton’s laws of gravity and suggested that light escaping from the surface of a star would have its speed reduced due to the gravitation pull of the star, and therefore if a star’s gravitation pull was strong enough even light would not be able to escape.[1] Using the approximate speed of light he reasoned that if an object was approximately 500 times the mass of the

dwarfs, neutron stars formed when the original star cannot support themselves against gravitational collapse by generating thermal pressure. They are born from once large stars that grew to be four to eight times the size of our sun before exploding. After the explosion, the only part of the star that remains is its core, but it no longer produces nuclear fusion. The neutron star density causes protons and elections to combine into neutrons, which is how the star got its name. Neutron stars rotate in space

milliseconds to a few seconds) neutron stars, which are the end products of the evolutionary stages of massive stars after supernova explosions. As the star collapses, the density becomes large, giving rise to a star consisting mainly of neutrons, with $\sim$ 1.4 {\Msun} and a radius of $\sim$ 10 km \citep{Lattimer13}. They have inferred surface magnetic fields of the order of 10$^{11}$ - $10^{13}$ G \citep{Beskin}, and are the most directly-observable remnants of dead stars in the Universe. Pulsar studies

Bryan Gaensler is an Australian born astronomer who is currently leading a team of Australia’s best astronomers in the ARC Centre of Excellence for All-sky Astrophysics (CAASTRO). His main field of study is cosmic magnetism which also encompasses the study of supernova remnants. Because magnetic fields are not visible to the naked eye or regular telescopes, Gaensler’s team must use radio telescopes to view the polarised radiation being emitted. By using radio telescopes to view the fields, they are

giants are dying stars that are in their last part of stellar evolution. Every star will eventually turn into a red giant over some point in time. Stars turn into red giants when there is no more hydrogen fuel for the star. Inside of a star, hydrogen goes through a process called nuclear fusion where hydrogen is getting converted into helium. Nuclear fusion helps create energy for the star so that the force of gravity isn’t crushing the star together. This is also the reason why stars are bright. When

1. What is the most basic method of determining stellar distances? EXPLAIN the method! There are various methods of determining the distances of stars. Some of them include the variable stars theory, parallax method, use of color and the expanding universe theory, just to mention a few. The method that is the most common and can easily be explained is parallax, which is well explained through illustration. When one holds an object high up front so that it blocks your front view and close one eye

The Milky Way contains billions of stars with different ages and sizes. One example of a star which is closest to earth is the Sun. Just like all the other stars the sun is a luminous ball of gas which mostly contains hydrogen and helium and is held together with its own gravity. All the stars produce their own energy by a process called nuclear fusion. Stars life begins in the place what astronomers call the Nebulae. A nebula is enormous cloud consisting of dust and gas; mainly hydrogen and helium

the star is a long process that has taken place for billions of years and will continue to take place long after our star is no longer in existence. In this essay I will be explaining the magnificent process of how a star is first born till the end of its life cycle. First, I will be explaining how the star is first formed in all its beauty big or small. Then, I will be explaining the path of an average star like our own sun will take. After, I will be explaining the journey of a massive star in all
