1. Astronomy Review

2. Terminology
Luminous
Revolution (year length) versus Rotation (day length)
Gravity (function of mass)
Planet < Star < Star system < Galaxy < Universe

4. Distances in Space
Convert between Kilometers, Astronomical Units and Light Years
The avg distance from Earth to Saturn is 1,427,000,000 km. What is this distance in AU?

6. AU

7. Distances in Space Calculating light’s speed
How long would it take light to travel the distance from Saturn to Earth? (d = 1,427,000,000 km )

8. Calculations in Space Unit Conversion
Saturn rotates every 11 hours and revolves around the Sun every 29 years. How many Earth days is one Saturn year?

9. The Effect of a Planet’s tilt
Earth tilts by 23.5°
This causes the seasons, NOT the distance to the Sun

10. Terrestrial Planets Mercury: Closest planet to the Sun
Venus: Farther than Mercury, but warmer because of a thick atmosphere of carbon dioxide that creates a strong greenhouse effect

11. Terrestrial Planets
Earth: Our home. Contains liquid water and protective ozone layer
Mars: Iron oxide makes this planet look red

12. Asteroid Belt
Asteroids

13. Space Rock

14. Gas Giants Jupiter: largest planet in the solar system
Saturn (clearly visible rings): shiny rings made of ice that reflect sunlight

15. Gas Giants
Uranus: tilted almost 90°

16. Gas Giants
Neptune: farthest planet from the Sun. Named after the Greek God of the Sea

17. Constellations
Ursa Major and Ursa Minor

18. Constellations Orion and Canis Major
Line up the stars in ‘Orion’s Belt’ and following the line south until you hit Sirius.

19. Stars
Polaris: The North Star is located in the Little Dipper / Ursa Minor.
Sirius: The brightest star in Earth’s sky is located in Canis Major

21. The Sun Powered through nuclear fusion
Sunspots: cool regions of the Sun that appear because of solar magnetic interference

22. The Sun
Solar flares and Aurora Borealis

25. Lifecycle of a Star Nebula Protostar Fusion Chain Reaction Begins
Fusion continues throughout life
If small-medium sized the star becomes a Red Giant -> White dwarf -> Black dwarf
If large sized = Supernova -> Neutron star OR Black hole

27. Features of Stars
Colour depends on temperature

28. The Big Bang Theory

29. The Big Bang Theory
the Universe was once in an extremely hot and dense state which expanded rapidly
According to the most recent measurements and observations, the Big Bang occurred approximately billion years ago, which is thus considered the age of the Universe.
