Cosmology and the distant Universe

This module introduces the science of cosmology, which aims to answer fundamental questions about the nature, history and future of the Universe. You’ll develop skills to use the mathematical tools and physical models needed to describe the Universe on the largest scales and examine how today’s stars and galaxies came to exist. You’ll also explore a variety of phenomena of the distant Universe, from the earliest galaxies to black-hole jets and gamma-ray bursts. You’ll use a range of observational evidence to test theoretical ideas throughout the module; at times, you’ll come up against the limits of our current understanding.

What you will study

The module introduces the fundamental concepts of modern cosmology and selected topics in extragalactic astrophysics. You’ll develop skills in applying the ideas of cosmology and the astrophysics of the distant Universe through problem-solving and using and interpreting observational evidence. You’ll explore how this evidence supports current theories about the Universe and its evolution and gain an understanding of current open questions and the limitations of our knowledge.

The module comprises printed books, supporting practical activities and online content.

Cosmology provides a thorough introduction to modern cosmology, beginning with an overview of current understanding to provide context for the more specialised topics that follow. You’ll then explore the basic concepts and mathematical language of special and general relativity, learning how these underpin our ability to describe the geometry of the Universe. The module introduces the metric describing the geometry of the Universe and the Friedmann equations that describe its expansion. You’ll learn how a small set of cosmological parameters define spacetime’s past and future evolution, then explore the key observational evidence supporting the current model and how observations measure these fundamental parameters. In later parts, you’ll follow a history of the Universe from the earliest particle interactions to the formation of structure via gravitational collapse and, eventually, the birth of stars and galaxies.

Three Python-based practical activities support this part of the module, providing hands-on experience working with cosmological models and observations.

The Distant Universe provides a series of in-depth study topics in extragalactic astrophysics, linked to each other and Cosmology by themes of relativity and the interaction of matter and radiation. You’ll examine how we find and study the first galaxies and learn about their impact on their surroundings. You’ll then consider in more depth how to use the technique of gravitational lensing – the bending of light by massive objects – to learn about distant galaxies and more nearby objects. You’ll also learn about the dynamic processes in the Universe’s most massive structures, galaxy clusters. Finally, the module introduces the topic of high-energy astrophysics; you’ll learn about observations and models of extreme phenomena, including jets from supermassive black holes and gamma-ray bursts.

Two further Python-based practical activities support Book 2 The Distant Universe.

You will learn

You’ll build on your mathematical, physics and astronomy knowledge to further develop your understanding of fundamental concepts in physics and astronomy in the specific context of cosmology and astrophysical phenomena associated with the distant Universe.

Vocational relevance

You’ll develop skills in quantitative and computational problem-solving and organising and assessing evidence to support arguments and ideas in astrophysics and cosmology. Coding is an important practical and professional skill; you’ll develop this through activities involving exploring real astrophysical data and models applying cosmology and astrophysics concepts.

Teaching and assessment

Support from your tutor

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

  • Marking your assignments (TMAs) and providing detailed feedback for you to improve.
  • Guiding you to additional learning resources.
  • Providing individual guidance, whether that’s for general study skills or specific module content.
  • Facilitating online discussions between your fellow students, in the dedicated module and tutor group forums.

Module tutors also run online tutorials throughout the module. Where possible, recordings of online tutorials will be made available to students. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part.

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.
