2. Halley’s Comet In 1705 Edmond Halley predicted the return of Halley’s using Newton’s Laws of motion and therefore the comet was named after him after he died

3. Halley’s Comet in 2024

4. Beginning of Universe BIG BANG THEORY: - universe began in an instant ~13.7 billion of years ago -Universe was very small, hot, dense, then a big explosion occurred -Universe expanded and cooled -atoms formed after a few hundred thousand years - Gravity caused first stars/ galaxies to form after 200 million years

5. End of Universe Many theories…. No proof Most scientists theorize the universe will continue to expand forever

6. Dark matter Matter that does not give off electromagnetic radiation Cannot be seen directly, is inferred by its gravitational effects on stars and light Astronomers do not know much about it, but it may make up 90% of universe!

7. Worm Holes Path between 2 points in curved space-time Short cut/ faster than the speed of life Introduced by Albert Einstein and colleagues Said to collapse if matter entered Time travel?? NO PROOF!

8. Aliens/ Life on other Planets? Not that we know of… But who knows??? How many planets are in the universe? so far, 9 in our solar system, and 185 orbiting other stars.But the real number is astronomically huge. There are about 400 billion stars in our galaxy alone. If each of them have the same number of planets (on average) as our own sun, then that's about 4 trillion planets in our own galaxy alone. Multiply that by an estimated 125 billion galaxies in the universe... that's a lot of planets.

9. NASA National Aeronautics and Space Administration Since 1958 Studies astronomy and physics to better understand the universe Is currently supporting the International Space Station www.Nasa.gov

10. International Space Station (ISS) space agencies of the United States, Russia, Europe, Japan, and Canada Been in orbit since 2000 Rotates crews Over 200 people have visited Orbits the Earth http://www.nasa.gov/multimedia/videogallery/in dex.html?media_id=97766082 http://www.nasa.gov/multimedia/videogallery/in dex.html?media_id=97766082 http://www.nasa.gov/multimedia/videogallery/in dex.html?media_id=97769982 http://www.nasa.gov/multimedia/videogallery/in dex.html?media_id=97769982
