1 The Life Cycle of Stars This is the death of a star (supernova) viewed by Tycho 400 years ago it was so bright you could see it with the naked eye

2 The Life Cycle of Stars Nebula AAAAA BBBBBB CCCCCCC DDDDDDDD EEEEEEEEE FFFFFFFF

3 The Life Cycle of Stars Nebula Main Sequence Star Red Giant White Dwarf Supernova Neutron Star Black Hole

4 Nebula All stars begin as a ball of gas & Dust in space

5 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

6 The stars expands to 10 – 100 times its original size The star has used all of its hydrogen fuel. The center shrinks. Red Giant

7 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.

8 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.

9 Neutron Star The materials are squeezed together so hard by gravity electrons and protons become neutrons.

10 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
