Life cycle fo a star
טקסט Storyboard
- Star life begins in a nebula, which is a huge cloud of dust and hydrogen that is pulled together by gravity.
- NEBULA
- The gas and dust start spinning, heating up, and contracting creating a prostar.
- HIGH MASS PROSTAR
- once a star has "turned on" which is when the gas and dust from a nebula become so hot that nuclear fusion starts, it is now a main sequence star
- HIGH MASS STARS
- When nuclear fuel runs out, the star swells in size and then the outer layers give the star a red color. It is now considered a red giant
- RED GIANT
- a dying red supergiant can explode. This is called a supernova,
- SUPER NOVA
- after a massive star explodes, a large amount of mass remains and the gravity of the mass is so strong that gas iis pulled inward pulling more gas into smaller space. it will become so strong that nothing can escape not even light.
- BLACK HOLE
