640-176 The Solar System and the Cosmos

Astronomy is one of the most rapidly changing branches of science. The latest results from the Hubble space telescope and other telescopes will be given. How they affect our understanding in a range of fascinating topics, such as black holes, other planets, comets and extraterrestrial life, will be discussed. Scientific methods used to investigate the solar system and the cosmos will be explained. Basic physical concepts required to understand the formation and evolution of our solar system, and also the structure of the universe on the largest scales, will be presented. Topics in cosmology will include Big Bang models, the 'missing mass' problem, and the first few seconds of the universe.

Students completing this subject will be able to:

• explain the structure of the universe, and be able to apply basic principles of gravity to describe the motions of objects in the universe; and

• solve quantitative problems using these principles.

In addition students will be able to:

• participate as an effective member of an astronomy laboratory and observing group;

• communicate their understanding of astronomy orally and in written form in lab classes; and

• manage their time commitments to this subject in order to be prepared for regular lab classes as well as tests and the examination.

A 3-hour end-of-semester written examination (65%); tests totalling up to two hours and/or written assignments during the semester, up to an equivalent of 2000 words (10%); laboratory work (25%). Students must complete both laboratory and assignment work satisfactorily to obtain a pass.
