Open any astronomy book or website and you will see figures quoted for the sizes, ages and distances of planets, stars and galaxies. What methods are used to determine these values? How much confidence can we have in these estimates? We will discuss some of the methods used and consider some of the pioneers who have made valuable contributions.
Course aim
To discuss some iof the methods that enable us to estimate the age, distances and sizes of astronomical bodies.
Do I need any particular skills or experience?
- This course is for beginners and improvers
By the end of the course I should be able to:
- Explain a method that can be used for estimating the distance and size to a planet.
- Explain ONE method of estimating the distance to a star.
- Explain ONE methods of estimating the distance to a galaxy.
- State the currently accepted value for the age of the Universe.
- Carry out research into topic(s) suggested by tutor or by yourself. If you feel confident in doing so, inform others in class of findings in writing (for publication on Canvas) or verbally. (NB: Presentation of your research is NOT compulsory)
What else do I need to know?
No prior knowledge is assumed. Please bring a notebook and pen. You may wish to carry out independent research between classes.
