What about this course:This is a one semester lecture plus laboratory course on astronomy with an emphasis on the study of the Sun as a star, measurement of different properties of stars, birth, evolution and death of stars, strange states of matter (neutron stars and black holes), Milky Way Galaxy, study of the Universe beyond our Galaxy, formation and evolution of galaxies.

As we consider more distant objects, such as active galaxies and quasars, we move backwards in time, ultimately arriving at big Bang. The course finally takes you to the current cosmological ideas.

The objective of this course:1- Demonstrate the methods that astronomers use to obtain information about the Sun, stars and Galaxies, 2- Discuss the properties of the Sun and list the layers of the Sun’s interior and atmosphere, sunspots and the effects of Sun activities on the Earth. Then 3- Describe the nature and evolutionary paths of stars from birth to white dwarf, neutron stars, or black holes. Then4- Demonstrate the properties and evolution of our galaxy, other galaxies and the entire universe. Also,5- Analyze the various methods used to measure distances out to the edges of the visible universe. 6- Explain the experimental basis for the Big Bang theory of the universe. Then7- Discuss our place in the Universe. Finally, 8- Discuss the possible existence of extra-terrestrial life in the universe.
