** __STORY__ ** One apon a time, about 5 billion years ago, nothing existed. But then (nobody knew how) something just blew up, creating our entire universe. This is called the Big Bang theroy becasue of the explosion. With that explosion, came Nebulaes. Nebulaes are clouds of dust and gas. They eventually turned into stars. One of the stars that was created in the Big Bang was named Twinkle. His Parrents, who were the leaders of the star community, desided all the stars should divide into large groups and go settle somewhere in space so their area wasn't over populated. All those stars agreed, and went sepperate ways, and thats how the galaxys were created. Twilkle, his parrents, his brother and all his new freinds settled in our current galaxy, the Milkey Way. Twinkle started school in the Milkey Way. He learned about how to be big and bright. Also he learned about the plannets that were formed form the same explosion that he was. "There is a myth that sometime in the future, the plannets will have these creatures called 'humans' and they will live on those plannets. But these humans aren't like you and me. They will be very cold and need the best one of you guys to be their sun to stay worm," Twinkles teacher told the class. Twilnke's goal was to be the best star in his class so he could be the sun of the Milkey Way and save the humans. But his brother, Shine, told twinkle that he was not good enough to be the sun of the Milkey Way. Twinkle wanted to prove his brother wrong. So he studdied twice as hard and managed to get good grades against his brothers prediction. In the end, Twinkle graduated top of his class and was nominated to be the sun of the Mikey Way. But there was another star up for the same title of the sun. His name was Bright. Bright had really good grades also. It was up to a vote of all the stars in the Milkey Way who would be the sun. Twinkle won by 24 votes! He went on to be the big, bright sun that we know today, and even though the stars dont know it, the myth they were tought in school came true. __ FACTS  __ Astronmy (Heather )
 * 1)  Sun is one of billion stars in the milky way galaxy.
 * 2)  Many galaxys, one universe.
 * 3)  Gakileo Galilei made 1st teliscope
 * 4)  Earths atmisphere interferes w/ teliscopes
 * 5)  So does light polotion
 * 6)  From earth to the nearest star (besides the sun) is 4.2 light years away
 * 7)  Another galaxy called Andromeda
 * 8)  Stars only IN galaxys, none inbetween
 * 9)  Leap years becasue a real year is a little over 365 days, to keep months w/ seasons the same, we need an extra day.
 * 10)  Can't see stars in day casue of sun
 * 11)  Stars also rise and set
 * 12)  Stars that don't rise and set are constilations.
 * 13)  You see different stars in different seasons

.  Acient Astronmy (Andrea) __   Ancient Times    __ 1. ancient people had better chance to study sky. 2. ancient priests studied the sky to correct calendars __ Far East Astronomy __ 1. some constellations stay in the north part of the sky. 2. sailors used stars to guide them home __ Early American Astronomy __ 1. Mayan’s studied Venus’s movement 2. Mayan’s studied the moon and sun for a next eclipse and made an accurate calendar.(better than Europe’s at that time.) __  Heavenly Motions   __ 1. thought earth was in the center __  Measuring Earth   __ 1. An astronomer figured that earth was25,000 and 40’000 km around(Erato Sthaves) Egyptian Sky Watchers 2. Egyptians where first to use a 365 day calendar 3. Made sundials to watch the sky __Babylons __ 1. they were the first to study the planets Mercury, Venus, Mars, Jupiter, and Saturn. __ Greece  __ 1. pointed out that evening and morning stars are the same body.       2. thought earth was flat or round and the moon’s light was reflected sun light. Big Bang (Kelby) 1 .       There is a lot of evidence today to support the Big Bang.- 2. Edwin Hubble discovered that galaxies everywhere are moving away from us. This supports the idea that the universe is growing ( it's fair to say that the Universe was smaller yesterday than it is today.). 3. To this day the Big Bang is still not complete. 4. In 1964 two US radio astronomers accidentally discovered that the entire Universe is filled with radiation lingering from the Big Bang. 5. About 15 billion years ago, a huge cosmic explosion made all matter,       what caused this to happen is a question we may never answer (According to the theory, there was no space and time before this, and therefore nothing to explode and nowhere for it to explode into.). 6. The Big Bang happened everywhere simultaneously creating space and time in an instant. 7. After the Big Bang the universe was very hot, but over time it began to cool and expand. Space filled with the building blocks of atoms (protons, neutrons …). 8. After thousands of years nebula’s developed. The nebulae’s became super hot, so hot that atoms fused together. 9. Nebulae’s exploded into balls of fire, creating the first stars! 5 billion years ago a star, that’s now are sun, was created in the same way. 10. Scientists believe that our galaxy was created 4.6 billion years ago. They think it started as a nebula that formed our sun.
