  • 1. There are more stars in the universe then there are specks of sand on Earth.

    2. How many Earths could fit inside the sun? 1.3 million

    3. If our Sun was the size of Betelgeuse it would reach out as far as the planet Jupiter.

    4. All stars begin as Nebulae.

    5. hundreds of new stars are born from one nebula.

    6. Dense parts of nebulas contain the most matter.

    7. In 2004 the Spitzer Telescope was launched. It is an infrared telescope, which means it measures the heat that passes through nebulas.

    8. Fill in the blanks for the equations: hydrogen + heat + pressure = stars More pressure = more (COULDN T FIND)

    9. At 15 million degrees, atoms begin to fuse together, and a star is born.

    10. Albert Einstein’s theories proved that stars tap into the energy of atoms. Complete his famous equation: E = MC^2

    12. Atoms release energy by fusing when they smash together.

    13. Hydrogen atoms crash together creating helium and energy.

    14. Why can fusion constantly occur in stars when people can only create it for a second? Constant heat, pressure and fuel are available

    15. Why don’t stars blow apart? Their immense gravity holds them together

    16. How long does it take light from the Sun to reach Earth? 8.3 minutes

    17. solar flares can damage satellites, spaceships and even astronauts.

    18. Every star will eventually die because its fuel runs out. fuel

    19. In about 7 billion years, our Sun’s hydrogen will run out.

    20. Gases in the sun will expand and it will turn into a red giant.

    21. The core of the sun then becomes unstable and the stars outer layers get blown away. Slowly it disintegrates and becomes a white dwarf.

    22. Giant crystals of pure carbon are at the center of a white dwarf.

    23. Giant stars create the building blocks of the universe when they die. What element do these massive stars make right before they die? The building blocks of life.

    24. When these massive stars explode it’s called a supernova and it is the most violent event in the universe. New elements are blasted far into space.

    25. nuclear power are left after a supernova. They are only about 20 miles across but very dense.

    26. What are five common elements in stardust? hydrogen, carbon, oxygen, silicon, and iron

    27. What becomes of this star dust? Planets, “people”, etc.

    28. According to the video, what will eventually happen to the universe? Everything will disappear.
