released by NASA on 3/11/2013 and talks about the discovery of the closest star system found in a century. NASA’s made this discovery through there Wide-field Infrared Survey known as “WISE”. WISE discover a pair of stars that is set as the third closest star system to the sun. The founding of these two stars is the closest system founded since 1916. Bothe these two stars are called brown dwarfs witch can be define as stars that are too small in mass to ever become hot enough to ignite hydrogen fusion

The article discusses the basic concepts of stars and some basic facts of astronomy the importance of the article that it shows how by using the spectroscopy technique we can determine the interaction between matter and radiated energy and discover that some objects give off and adsorb different spectrum of light. The article makes you understand the different stages of the lifecycle of the sun. Astronomers study light which comes from distant objects to determine its composition‚ temperature‚

prison cell. The dark blue sky littered with stars is the first thing that catches my eye. ‘Sometimes I wonder what the stars are doing when they are not out twinkling in the night sky. Perhaps the stars are shy and only twinkle when we are asleep. That would be slightly ironic considering how much attention they draw to themselves. ‘ ‘Maybe they’re afraid of the sun?’ ‘That isn’t that crazy of a thought‚ but I’d rather say that instead of the stars being afraid of the sun‚ they are trying to compete

CONSTELLATIONS AND STARS There are about 48 old constellations. Today astronomers recognize 88 (44 in each hemisphere) dividing all of the entire sky. THE GREAT BEAR AND THE SEVEN STARS Probably the most famous group of stars is the Big Dipper. It is a part of the constellation called Ursa Major. It resembles a bear in many civilizations. The handle of the Dipper is the tail of the bear curving away from the bowl. THE LITTLE BEAR AND POLARIS: Five major constellations are always visible above the

Science of Stars Nancy Vasquez SCI 151 September 23‚ 2012 Robert Austin Abstract When discussing the Solar System‚ the planets are what are mostly thought of. Many other objects orbit around the sky such as stars‚ asteroids and meteors. Stars have many properties of which will be discussed throughout this paper. Properties of Stars * Stars are determined by their brightness‚ distance‚ luminosity‚ radius‚ chemical composition and temperature (Strobel‚ 2007). * When determining

Life cycle of Stars Our Sun is a perfect example of a star‚ and there is an incredible amount of stars in the Universe. Stars live for a very long time; millions‚ billions‚ or tens of billions of years so we can never really observe the life of a star; its birth‚ life‚ and death. In determining the life cycle of a star‚ astronomers observe many of the billions of stars around us and see them at different stages of life‚ therefore putting together a star’s evolution. It is a star among hundreds

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. Protostar: A protostar is when the gas has clumped together and it getting hot but has not reached what is

The paper will also explain in detail the properties of stars and what is a Hertzsprung - Russell diagram. The sun is explained to have a lifecycle‚ and its nature of where it is in its lifecycle‚ and all the properties of

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. The
