Galaxies, stars and planets

Galaxies, stars and planets is one of a series of short, five-month 10-credit modules introducing fascinating topics in science. It covers the exploration of our solar system; the discovery of planets orbiting other stars; the birth, life and violent death of stars; and the creation of the Universe itself. With a choice of start dates it enables you to try out an area of study before you commit yourself to a longer module, or top up your knowledge and skills between longer modules. 

Standalone study only

This module is available for standalone study only. Any credits from this module cannot be counted towards an OU qualification.

What you will study

Have you ever gazed up into the sky and wondered what lies in the distant reaches of space? This module explores the fascinating science behind the galaxies, stars and planets of the Universe. It will develop your understanding of a wide range of topics in astronomy, with sections on the Sun, planets, stars, extraterrestrial life, galaxies and the origin and evolution of the Universe.

This module explains how the Sun gets its energy and how astronomers are able to observe the Sun, even into its interior. You will be introduced to the planets, their satellites and the minor bodies of the solar system. You will also meet exoplanets, i.e. planets around other stars. The latest ideas about the life cycle of stars, from birth to death, and the cosmic re-cycling of their components are also explored.

You will also meet ideas about the expanding Universe, dark matter, dark energy, the large-scale structure of the Universe and what we know about the very early Universe, shortly after the 'Big Bang'. Many of these topics are at the cutting edge of our understanding but are dealt with in an approachable and (largely) non-mathematical way.

Finally, life beyond Earth is considered, including its requirements and possible habitats, and the likelihood of alien life – including intelligent life.

Through a series of structured activities you will learn to use the Aladin Sky Atlas (Aladin) program on a PC for interpreting and manipulating astronomical images from space telescopes and ground-based telescopes. Aladin is a leading astronomical software package that is used by professional astronomers and will help you make the transition from just appreciating beautiful astronomical images to also doing quantitative science.

If you are a beginner in science, you will find that the study book introduces new scientific ideas as you need them, progressively developing more sophisticated concepts and skills. If you are an amateur astronomer, or have read popular books on astronomy, you will find that the module develops your understanding and introduces areas of astronomy that you have not met before.

The module is based on a specially written Open University (OU) study book and a website. The website gives you access to astronomical images from some of the biggest telescopes on Earth and in space. The study book provides questions and some activities to help you to test your understanding. You can also use these for self-assessment as you progress through the module. A number of activities will only be presented online via the website.

You have to submit the single piece of written work for assessment after 21 weeks. There will be no other opportunity to complete the module.

Future availability

Galaxies, stars and planets (S177) starts once a year – in October. This page describes the module that will start in October 2019. It will start for the last time in October 2019 – there’s no planned replacement.

Regulations

As a student of The Open University, you should be aware of the content of the academic regulations which are available on our Student Policies and Regulations website.

    Course work includes:

    End-of-module assessment
    No residential school


    Entry requirements

    This module is for people who are new to the subject area. You need little more than an interest in astronomy and the motivation to discover more about it.

    Mathematically, you need only to be able to add, subtract, multiply and divide simple numbers. The structured teaching will take you to a level at which you are happy to use maths as a tool in a range of scientific contexts. A maths skills ebook is provided to help you with, for example, fractions, percentages, reading graphs and tables, and scientific units as required by the module.

    To cope with the written material you should be able to read and understand written English of a style and complexity characteristic of a professional magazine or quality newspaper, and you should be able to communicate your thoughts clearly and comprehensibly in a written format.

    If you have any doubt about the suitability of the module, please speak to an adviser.

    Additional Costs

    Study costs

    There may be extra costs on top of the tuition fee, such as a computer, travel to tutorials, set books and internet access.

    If you're on a low income you might be eligible for help with some of these costs after your module has started.

    Ways to pay for this module

    Open University Student Budget Account

    The Open University Student Budget Accounts Ltd (OUSBA) offers a convenient 'pay as you go' option to pay your OU fees, which is a secure, quick and easy way to pay. Please note that The Open University works exclusively with OUSBA and is not able to offer you credit facilities from any other provider. All credit is subject to status and proof that you can afford the repayments.

    You pay the OU through OUSBA in one of the following ways:

    • Register now, pay later – OUSBA pays your module fee direct to the OU. You then repay OUSBA interest-free and in full just before your module starts. 0% APR representative. This option could give you the extra time you may need to secure the funding to repay OUSBA.
    • Pay by instalments – OUSBA calculates your monthly fee and number of instalments based on the cost of the module you are studying. APR 5.1% representative.

    Joint loan applications

    If you feel you would be unable to obtain an OUSBA loan on your own due to credit history or affordability issues, OUSBA offers the option to apply for a joint loan application with a third party. For example, your husband, wife, partner, parent, sibling or friend. In such cases, OUSBA will be required to carry out additional affordability checks separately and/or collectively for both joint applicants who will be jointly and severally liable for loan repayments.

    As additional affordability checks are required when processing joint loan applications, unfortunately, an instant decision cannot be given. On average the processing time for a joint loan application is five working days from receipt of the required documentation.
