Ever wondered what lies beyond our own solar system? Through lectures and demonstrations this course considers the different types of stars and their lives from formation to stellar graveyard. We look at how the elements come together to form galaxies, how galaxies warp space-time with their gravity, and how the universe formed in the Big Bang. An evening of star viewing in the Blue Mountains is included.
1. Introduction and review of basic concepts
We set the scene, showing where we are in the universe, and introducing concepts and terminology will need, such as spectra, magnitudes, radiation.

2. Characterising and classifying the stars
We show what the spectra of stars look like, and how they are classified into a meaningful sequence.

3. The interstellar medium; and The Sun
We look at the gas between the stars, the building blocks for everything else; and we look at our Sun, the nearest star.

4. The evolution of the stars
We look at how stars evolve as they age, and why the changing internal structure of a star leads to massive changes in its outward appearance.

5. Stellar graveyards: white dwarfs, neutron stars and black holes
We look at the objects that are the ultimate fate of stars, and discuss how we find stars that are no longer shining.

6. Binaries, clusters and variables
We look at special types of stars, and how we can use them as yardsticks for the universe.

7. Our galaxy: putting the pieces together
We look at how all these elements come together to make the Galaxy.
8. Galaxies: normal galaxies to quasars
9. Cosmology: the universe as a whole
10. Gravitational lensing
There will be an evening of star-viewing at Mount Wilson on
|Saturday, 17th October|
We will have an extra viewing evening from the roof of the Physics building during the second half of the lecture on
|Wednesday, 30th September (lecture 3)|
