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‚

sub-classifications‚ and differentiated from each other by their mass and the appearance of hydrogen in their spectra‚ (or‚ the light it gives off). The Type I supernova occurs in binary pairs‚ lacks the hydrogen in its spectra‚ and originates from a white dwarf‚ (stars that are already dead)‚ occurring when the gas of a nearby star accumulates‚ compressing the star until the reaction is triggered (Thomp). While a star may die without becoming a supernova‚ it is the explosive properties of the death that

Process and importance of fusion in stellar evolution. Huge clouds of hydrogen atoms and gravity cause the atoms to be attracted to each other creating them to slowly move towards the centre of mass.The atoms then continue condensing until something happens.All of the atoms are trying to get to the centre of mass. While this is happening the temperature becomes 10 million Kelvin and at that point there is enough temperature and enough pressure to overcome the coulomb forces‚ bringing the two protons

glowing protostar; this stage lasts for roughly 50 million years. If there is enough material in the protostar‚ the gravitational collapse and the heating continue. If there is not enough material in the protostar‚ one possible outcome is a brown dwarf (a large‚ not-very-luminous celestial body having a mass between 1028 kg and 84 x 1028 kg). A Newborn Star: When a temperature of about 27‚000‚000°F is reached‚ nuclear fusion begins. This is the nuclear reaction in which hydrogen atoms are converted

The Grimm Brothers’ “Snow White with the Seven Dwarfs” addresses many issues in our real life‚ although the tale is not real everything is imaginary‚ it is far from a vacuous work devoid of real-world significance. But the story discussed feminist issues of women’s gender roles‚ standards of feminine beauty‚ and aging‚ “Snow White” also addresses the sociological subjects of child abuse‚ neglect‚ and mistreatment. As Snow White is a weak protagonist and neglected by her stepmother because she has

swells into a RED GIANT (it becomes red because the surface cools). A small-to-medium-sized star like the sun then becomes unstable and ejects its outer layer of dust and gas as a planetary nebula * This leaves behind a hot‚ dense solid core- a WHITE DWARF which just cools down and eventually fades away (That`s going to be really sad). * Big stars ‚however‚ form red supergiants- they start to glow brightly again as they undergo more fusion and expand and contract several times‚ forming heavier

The brightest stars in Libra form a quadrangle that distinguishes it for the unaided observer. Alpha Librae‚ called Zubenelgenubi‚ is a binary star divisible in binoculars‚ 77 light-years from Earth. The primary is a blue-white star of magnitude 2.7 and the secondary is a white star of magnitude 5.2. Its traditional name means "the southern claw". Zubeneschamali (Beta Librae) is the corresponding "northern claw" to Zubenelgenubi. The brightest star in Libra‚ it is a green-tinged star of magnitude

Dr. Miller also explained a lot about the star constellations‚ but one thing that stuck out to me was that the star Sirus‚ has a cousin that is a white dwarf star. The third event was a presentation by Professor Alan Marscher. His presentation was on Black Holes‚ Jets‚ Gamma Rays and Active Galactic Nuclei. Alan started off by talking about black holes and their makeup and general structure. He did
