Introduction to Astronomy - 1st year

A course in descriptive astronomy which covers the entire panorama of the universe from the origin and structure of the solar system, to the properties, origin and evolution of stars, galaxies and cosmology.


By the end of the course, students will be able to:

1. Conceptualize the structure of the solar system and the universe;

2. Classify and explain the reason for the differences between the planets in our solar system, stars in the sky and types of galaxies in the universe;

3. Construct drawings correlating various planetary, stellar and galactic motions;

4. Trace the evolution of stars and the universe;

5. Relate the earth, our sun, our galaxy and in general, our location to the rest of the universe.
