STARS

Hey guys I'm going to be talking about stars yea that thing in the sky that you look at every night . Sometimes you cant see many or any stars because of light pollution we see allot less stars. Years ago we used to see almost every star in the sky. Stars are born in nebulae with many clouds of dust and gas. Some of the gas  in a nebulae is hydrogen gas. Over millions of years of gravity causes the hydrogen gas to collect in a cloud and more and more gas is pulled into the cloud it begins to spin as the cloud spins atoms of hydrogen gas bump into one another. The faster the gas spins the more the atoms bump togethr.
