Climate
Inside Hurricane Katrina

7. Astronomy Definition: The study of the universe
Studying objects in our own solar system and the universe helps us better understand Earth
We will discuss:
The history of astronomy
The solar system
Properties of stars, stellar evolution, and the universe
Horse Head Nebula
