The Life and Death of Stars (Astronomy) PowerPoint Presentation

The Life and Death of Stars (Astronomy) - PowerPoint Presentation ExampleMost prominent stars were grouped together and brightest of them both were given names. The grouping of stars also helped the astronomy to track motion and positions of other heavenly bodies .It was by this bring in that an idea came up of creating calendars where their used the motion of fair weather against the background stars. The widely used calendar in the world, The Gregorian Calendar, Which was based on the angle of earths rotational axis and the sun.How was the star create according to the astronomys? All stars are born from collapsing dust and cloud of gases which are concentrated at temperatures for a period of years. When the protostars settles down at an average temperatures to form a main eon star. Most of its life the stars uses nuclear fusion which is generated through fusion of hydrogen atoms at the core of main sequence star. The reason behind ganging up of stars in pairs or multiple aroun d the milk way maybe because of the spinning dust and clouds of collapsing dust causing a break up of two or triad blobs.During formation of a star not all gas and dust is used up, The remaining materials becomes planets, comets, asteroids or may remain as dust. For a star to be as big as the sun it requires 50 million years from the beginning of the collapse till adulthood,where else our sun will remain in that state for 10 billion years. The helium formed in the interiors by the reaction of hydrogen fuels provides draw which keeps the stars from collapsing under its own weight and produces energy which keeps on shinning.When the helium at the core of the star is closely exhausted, allnatural occurring elements heavier than Hellium are formed via supernova nucleosynthesis or stellar nucleosynthesis. Supernova nucleosynthesis occurs when massive stars explode while stella nucleosynthesis occurs during their lifetimes. During the end lifetimesof the star on that point
