Degree exam (2 papers) - 55%; Tutorials - 10%; Labs - 15%; Class tests - 20%.

To present a general introduction to the subject of astronomy and in particular the areas of solar system physics, positional astronomy and dynamical astronomy and in the context of the wider universe: namely stars & galaxies and cosmology;

To introduce students to some practical aspects of astronomy through laboratory work;

To encourage students to organise their time and work effectively; 

To introduce students to aspects of observational techniques in astronomy.

On completion of the course, the student should be able to:

(1) describe the structure of the sun, the planets, the satellites and other minor bodies and the structure and origin of the solar system;

(2) state the fundamental physical laws of blackbody radiation, gravitation, the gas laws and radioactivity;

(3) apply the above laws to describe and explain the properties of the bodies in the solar system and the evolution and formation of the solar system;

(4) state the fundamental formulae of spherical trigonometry and be able to apply them to planetary motion and terrestrial navigation;

(5) describe the various co-ordinate systems and how to transfer between them;

(6) solve problems concerning apparent motion of stars in the night sky;

(7) state the basic concepts of Newtonian gravitation and associated phenomena;

(8) use these concepts quantitatively in various situations such as deriving surface gravity and escape velocities and determining properties of planetary orbits;

(9) describe the electromagnetic spectrum, associated units and properties of the sky in different spectral regions;

(10) explain the use of telescopes including quantitative assessment of various properties and consideration of ancillary instrumentation;

(11) describe the main types of stars, the spectral classifications of stars and the Hertzsprung-Russell (HR) diagram;

(12) state the physical principles needed to build simple models of main sequence stars;

(13) state the relationship between stellar evolution and the HR diagram;

(14) describe the nature of gravitational collapse and be familiar with the properties of compact stars and black holes;

(15) list the observational evidence relating to these stellar states;

(16) describe the properties of the main types of galaxies;

(17) describe the large scale structure (clusters and superclusters) in the universe and their relative scales;

(18) explain the big bang model and its status in relation to cosmological observations.

The student should also: carry out practical investigations in elementary astronomy, taking and analysing data and reporting on their findings in written form.
