1 Stars and Galaxies

2 The closest star to us The sun

3 A cluster of stars A galaxy is a cluster of stars together

4 The universe The universe is everything in space

5 The different types of universes

6 Stars make up galaxies which make up the universe

7 The different types of galaxies Draw three boxes each with a title and a picture of the galaxy in the box Spiral Galaxy Irregular Galaxy Elliptical Galaxy

8 What makes one star different from another? 1.Mass determines lifespan of star 2.Flame demonstration: predict on left side order from coolest to hottest. (orange, white, yellow, red, blue)

9 The color of a star tells its surface temperature Remember: ROYWB A star’s color tells you how hot its surface is. From coolest to hottest: Red, orange, yellow, white, blue

10 Size of stars

11 A star is born Nebulas- dust and debris collecting in space

12 Protostar Star is being formed from nebula dust and debris

13 Star is formed=main sequence

14 Dying star

15 Super nova Explosion moving at about 6 million mph!! OR

16 White dwarf star  Black dwarf star

17 A star has died

18 Neutron Star If the star is at least 1.5 but less than 9 times larger than the Sun, the core left after the supernova will collapse into a neutron star. This is a star composed only of neutrons. Black Hole If the star is at least 9 or more times larger than the Sun, the core will continue to collapse into a black hole, an extremely dense area with a strong gravitational pull that light can not escape. Neutron Star or Black Hole?

19 Types of Galaxies – Quasars… A quasar is a distant galaxy with a black hole at its center. As enormous amounts of gas revolve around a black hole, the gas heats up and shines brightly.

20 See board Diagram of Stars life

21 Life cycle of a star (no dwarfs here)
