Nebula
Main Sequence Star
Red Giant
White Dwarf
Supernova
Neutron Star
Black Hole
Nebula
All stars begin as a ball of gas & Dust in space
Venus and the International Space Station crossing the sun.
Main Sequence Star
Has a Temp. Near 5,000 -6,000 C
Nuclear fusion occurs at the core converting Hydrogen to Helium.A star’s longest stage.
The stage of our SUN
The stars expands to 10 – 100 times its original size
The star has used all of its hydrogen fuel. The center shrinks.
Red Giant
White Dwarf
These are small hot stars near the end of their life.
Has a Temp. Near 10,000 C
Left over centers of old stars remain at this stage.
Supernova
This is the death of a large star by explosion
Generates a HUGE amount of light, brighter than a whole Galaxy, and may be seen with naked eye.
Neutron Star
The materials are squeezed together so hard by gravity electrons and protons become neutrons.
Black Hole
Left over from a supernova and very massive
So massive light can not escape. The mass of 3 suns and about 6 miles across
