Exploring the Universe (Online)

Overview

How old is the Universe? How unusual is the Solar System? How do we know what stars are made of? How will it all end? Oxford astronomers Chris Lintott (BBC’s Sky at Night) and Robert Simpson (zooniverse.org) provide an overview of the last 13.7 billion years of cosmic evolution, and the future of the Universe, answering these questions and more. The course will take participants to the cutting-edge of astrophysics.

Listen to Professor Chris Lintott talking about the course:

Covering cutting-edge ideas, techniques and discoveries in astrophysics, they aim to tell the scientific stories behind the beautiful pictures produced by the world’s largest telescopes.

We strongly recommend that you try to find a little time each week to engage in the online conversations (at times that are convenient to you) as the forums are an integral, and very rewarding, part of the course and the online learning experience.

Certification

To earn credit (CATS points) for your course you will need to register and pay an additional £10 fee for each course you enrol on. You can do this by ticking the relevant box at the bottom of the enrolment form or when enrolling online. If you do not register when you enrol, you have up until the course start date to register and pay the £10 fee.

See more information on CATS point

Coursework is an integral part of all online courses and everyone enrolled will be expected to do coursework, but only those who have registered for credit will be awarded CATS points for completing work at the required standard. If you are enrolled on the Certificate of Higher Education you need to indicate this on the enrolment form but there is no additional registration fee.

Assignments are not graded but are marked either pass or fail.

All students who successfully complete this course, whether registered for credit or not, are eligible for a Certificate of Completion. Completion consists of submitting the final course assignment. Certificates will be available, online, for those who qualify after the course finishes.

Course aims

This course aims to provide an overview of the last 13.7 billion years of cosmic evolution and the future of the Universe, covering cutting-edge ideas, techniques and discoveries in cosmology and astrophysics.

This course will enable participants to gain an understanding of the ideas underpinning modern cosmology and astrophysics, engage independently with the scientific literature on the topic and to discuss what is still unknown.

Learning outcomes

By the end of this course students will be expected to understand the evidence supporting current theories of cosmology, star and planet formation, together with their implications for our understanding of the Universe.


By the end of this course students will be expected to have gained the following skills:

  • Ability to critically assess astronomical ideas and theories and to be familiar with the current consensus view(s) in the scientific community.
  • Ability to independently search for relevant information to inspire and answer questions.
  • A familiarity with navigating and critiquing popular and technical material on the web.
  • Ability to discuss scientific ideas with their peers in a reasoned and well-argued fashion.

Assessment methods

You will be set two pieces of work for the course. The first of 500 words is due halfway through your course. This does not count towards your final outcome but preparing for it, and the feedback you are given, will help you prepare for your assessed piece of work of 1,500 words due at the end of the course. The assessed work is marked pass or fail.
