•Stars make sunshine through the process of nuclear fusion. Hydrogen atoms smash together with such force they create a new element, Helium.

•Stars go through a “life cycle”. They enter the main sequence when fusion starts and “die” when Hydrogen fuel is used up.

•Stars are not randomly distributed around space. They form groups of billions of stars called galaxies.

UniverseUniverse
•Everything.
UniverseUniverse
•The universe is believed to have expanded from an infinitely dense and infinitely hot point. The Big Bang.
UniverseUniverse
•Evidence that supports the Big Bang model of the universe includes the red-shift of distant galaxies and cosmic background radiation.
UniverseRed Shift of Distant Galaxies
•All galaxies have a color that is redder than they should be. This is caused by the moving of the galaxy away from the Earth. The Doppler Effect.
UniverseCosmic Background Radiation
•If the universe had a beginning, there should still be left over heat. The CBR is the left over heat of the big bang.
