Short Description

To survey our present understanding of our Universe and of our Solar System with the Sun as the source of energy for life on Earth, together with the possibility of life elsewhere.


Daily at 1.00 pm

Requirements of Entry



One 2 hour examination (70 %), continuous assessment (30 %)

Main Assessment In: December

Course Aims

1. To survey our present understanding of the Solar System and of the Sun as the source of energy for life on Earth, together with the possibility of life elsewhere.

2. To provide in this context, for students who do not propose to enter an Honours course in physics, some understanding of how data are gathered, evidence assessed, and argument conducted in a physical science.

3. To convey some appreciation of key episodes in the historical development of our knowledge of the Sun and the Solar System.

Intended Learning Outcomes of Course

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

1. Exploring the Sky.

  Provide an understanding of the astrophysical objects which can be seen. Describe how these

  are located in terms of angular position and, for the Solar System, in terms of distance from  


(2) The Inner Solar System & The Outer Solar System.

  Explain how the modern view of the orbits of planets and other bodies developed in the context 

  of the Copernican revolution and Newton's mechanics.

  State how we currently view the variety of environments provided by the individual bodies of

  the Solar System, and how we interpret the evolution of that system.

(3) The Sun and its Radiation.

  Explain how nuclear reactions drive the Sun as an energy source radiating to the planets, and

  how radiation gives the means of accessing information about distant bodies.

(4) Life in the Cosmos.

  Explain how specific are the conditions Earth satisfies to be able to support life.

  Describe the range of scientific disciplines needed to assess whether other life-bearing

  environments exist, and in particular for the life forms to communicate.
