  1. A Universe of Stars The Strange and the Amazing

  2. Nebulas

  3. THE BIG DIPPER

  4. The Sun Contains 99.8% of all the mass in the Solar System 700 Million tons of hydrogen converted to helium every second Average surface temperature of 10,000 Fahrenheit

  5. Our Closest Star Mars Proxima Centauri 54.6 Million Kilometers 34 Million Miles 4.2 Light Years Away 24 Trillion Miles

  6. Dwarf Stars • Red Dwarf • Blue Dwarf • White Dwarf • Black Dwarf • Brown Dwarf • Yellow Dwarf

  7. Giant and Supergiant Stars 4-70 times the mass of the Sun Short life spans

  8. Stars that go Nova • Only occurs in binary systems • A star can go Nova several times

  9. Supernova in Galaxy NGC 4526 • Supernovas can be brighter than the entire galaxy

  10. Neutron Stars 1 teaspoon of it’s matter would weigh a billion tons on earth Rotates 10-100 times per second 1 solar flare releases 100 times the energy the sun does in a year

  11. Black Holes • Remains of a supernova star with a mass at least 10 times that of the sun • The Black hole at the center of the • Milky Way galaxy has the mass of • 1 million suns • Gravity so great not even light can escape

  12. Quasars • Releases more energy than • Hundreds of galaxies combined • A trillion times brighter than • The sun • Thought to be matter trapped • In the accretion disc of a • Super massive black hole

  13. Exiled Stars Star that has escaped the gravity of their galaxy Slung out of a Black Hole Move at incredible speeds

  14. The Unknown For all of the stars we have seen and recorded in the Universe, over 99 percent of them are unaccounted for
