Module description

This module examines in detail the physics of our nearest star and of its interaction with the Solar System. Topics covered include the Sun's structure, energy production and transport processes, solar activity, the solar wind and its interaction with planets and comets.

Learning outcomes

After taking this module students should be able to:

Additional learning activities

Use of solar telescope to observe sunspots.
