Module Overview

Astronomy, Environmental & Energy Physics

The first part of the module is an introduction to astronomy. It will apply basic physics concepts that the learner has already encountered (e.g., centripetal acceleration) to space-related phenomena. It will also introduce new concepts required to deal with these phenomena. It will allow the learner to see how the fundamental physics they have already obtained can be applied to the extreme environments encountered, with particular those within our own solar system.

The second part of this module will deal with the physics of the environment and renewable energy. The first part of this section will look at the global energy budget, the greenhouse effect, global warming and its implications. The second part of this section will look energy use in Ireland and investigate various forms of renewable energy and nuclear power.

Using the naked eye to find some of the major constellations and brighter stars and deep space objects. Distinguishing a star from a planet without a telescope. Using the stars to find north and estimate your latitude on the Earth.

•    Introduction to the Magnitude Scale
Apparent magnitude, luminosity, intensity and Stefan’s law.

•    A Tour of the Solar System
The Sun, the inner planets, the outer planets and small solar-system bodies. The formation of the solar system.

•    Celestial Mechanics
