star formation comic big history
This storyboard does not have a description.
Here are the 5 stages of a star forming.
Stage 1: The star starts as a dense cloud of gas and dust that contracts under it's own gravity.
Stage 2: The gas cloud starts to heat up and glow. Then forms protostars. This takes 10 million years.
Stage 3: The newly formed star starts to produce strong stellar winds. These push away the gas and molecules around it to let the forming star become visible.
Stage 4: If the protostar gains enough matter and it's core temperature reaches 15 million degrees, then the nuclear reaction will occur where the hydrogen of the star fuse to form helium.
Stage 5: Finally gravity's compression balances with outwards pressures and gives the stars a solid shape. The star begins to release energy stopping it from contracting and causing it to shine.
