When a large star runs out of fuel,gravity will collapse the star so quickly it will create a massive explosion called a supernova.
The remains of a supernovae are large clouds of dust and gas called interstellar clouds.
The cloud of dust and gas begins to clump together due to gravity, and gives light due to internal heating. This clump is called a PROTOSTAR.
An interstellar cloud is an area of space that accumulated a lot of dust and gas. They are stellar nurseries,a place where new stars are born./ A nebula is a type of interstellar cloud.
TO GET TO THE ORION NEBULA YOU WOULD HAVE TO TRAVEL 1500 LIGHT YEARS!!!
Phases to our solarsystem Phase 1 Spinning: As each atom moved, they attached to others due to gravity. All of this moving energy averaged out in one direction. This caused the solar system to spin. Phase 2 Flattening: Gravity pulled the gas and dust closer to the center. This made the solar system spin more rapidly. this caused the solar system to flatten into a disc.
