  • 1. Exploring Space By: Madison
  • 2. The Sun
    • the Sun is our light resource
    • It takes 1.3 million Earths to fill the Sun
    • The Sun has 6 layers
    • The Sun has been active for4.6 billion years and has enough fuel to last 5 billion more years
    • Sunspots are dark depressions with a photosphere with a typical temperature of 4,000 degrees Celsius
  • 3. The Solar System
    • We have 8 planets, but we used to have 9
    • Most of the things in the Sun’ s gravity orbit in a clock wise direction
    • The terrestrial planets have rocky surfaces like Earth, Mercury, Venus, and Mars
    • The Juan planets are made of gas like Jupiter, Saturn, Uranus, and Neptune
  • 4. Milky Way
    • There are about 200 billion stars in the Milky Way
    • A beam of light takes 100,000 years to go all the way across the Milky Way
    • It takes 250 billion years to make a full orbit around the Milky Way
    • The Milky Way is a spiral galaxy
    • The Milky Way can only be seen edge on no matter where you are on Earth
  • 5. Galaxies
    • There are 3 types of galaxies: Spiral, Elliptical, and, Irregular galaxies
    • Spiral galaxies are probably the most beautiful galaxies there are
    • Galaxies are flat like a disc, but they’ re round like a ball in the middle
    • Elliptical galaxies are giant swarms of stars
    • Irregular galaxies airs misshapen clusters of stars
  • 6. Future of the Milky Way
    • Andromeda and the Milky Way are approaching at about 300,000 miles per hour
    • In 3 billion years, a huge cosmic crash will happen
    • Millions of stars will be flung into Space
    • The 2 galaxies will finally merge into 1 galaxy
  • 7. Black Holes
    • Black holes are the most puzzling and fascinating things in Space
    • Black holes are religions of Space where gravity is so intense, nothing escapes
    • Stellar black holes form when massive stars die
    • Super massive black holes are much bigger than stellar black holes
