Transcript of The sun

By: Matia & Lindsey The Sun Chemical composition Discovery . Solar Radiation Flares . Sunspots Sunspots sunspots Sunspots=lower temperatures . source of solar flares . . have intense magnetic activity core . the density of the sun's core is 150 times the density of water . The sun's core is the only place in the sun to create thermal energy . the core takes up 20% - 25% of the sun Life phases red giant white dwarf black dwarf . . . 5.5 billion years, the sun will use most of its hydrogen
becoming a red giant the red giant will eventually explode turning into a white
dwarf when all energy drains from white dwarf, it will
turn into a black dwarf Solar storms . Primarily composed of Hydrogen,
helium, oxygen, carbon and other chemicals . The sun formed by inheriting
its chemical compositon using
inerstellar medium Albert Einstein found how our sun works with his equation E=mc 2 . No one knows who discovered the sun, it's been in our solar system for generations Sun's core . No energy Interesting facts . largest star in solar system . Ancient egyptians called the sun Ra . Ancient greeks called the sun Helios . Ancient Romans called the sun Sol Technology . Mission SOHO lauched in December, 1995 . Ever since we used a Space telescope . We recieve a stream of 250 MB of data about the sun daily Watch a cool video can effect earth's
radio communications a solar flare is a
sudden brightening on the sun Location of the sun . the sun is in the center of the solar system . the sun's gravitational pull keeps all the
planets, dwarf planets, astroids and comets in our solar system Eclipses . Radiative zone . 45% of the sun's radius . energy extended from core . gas molecules get heated and turn into other gas molecules, this process continues forever . temperature is 15 million degrees celcius Convective zone . next layer from radiative zone . photons make their way out . from 6000-1 000 000 degrees celcius Photosphere . lower part of atmosphere . what we see of the sun from earth . 500 km thick 5,500 degrees celcius . the photosphere Chromosphere . reddish colour because hydrogen atoms are in exite state creating radiation . temperatures range between 6000 - 50,000 degrees celcius . Corona outer layer of the sun's atmosphere . extends for millions of miles . temperatures that can reach 1 million degrees celcius . has holes in it's magnetic field which probably create solar wind THE END
