Describe the evidence that early astronomers & philosophers used to demonstrate that the Earth is round, and explain how they were able to estimate the size of the Earth?

Describe the motion of the planets through the Earth's sky, and explain how this motion was accounted for in geocentric and heliocentric models of the solar system?

Explain why the tilt of the Earth's rotation axis and the Earth's elliptical orbit do or do not have a significant impact on the Earth's seasons of weather?

Describe the phenomenon of diffraction and how it affects the ability of telescopes to resolve point sources of light?

Describe how astronomers can determine the temperature of the sun and its total power output (energy released over time) using the spectrum of radiation it emits and the known diameter of the sun?

Describe how energy is produced in the sun's core and how this energy is carried out to the sun's surface?

Describe how spectroscopic binary stars and eclipsing binary stars are detected?

Describe the differences between sun-like and high mass stars in the main sequence stage and how this affects their relative lifetimes and interior structures?

Explain why stars leave the main sequence stage, and describe how the difference in mass between sun-like stars and high mass stars causes the evolution of these two groups to diverge when they leave the main sequence stage?

Describe the different types of supernovae and what their differences indicate about their origins?

Explain why light cannot escape from a black hole, and how astronomers are nonetheless able to detect black holes?
