The night sky

It’s January. The holiday is over, and you have already broken your New Year’s resolutions. What is there to look forward to?

Travel back in time and space to just before the Sun was born then move forward into the future to watch a star die. Exciting enough? Stick with us, and explore places you could never imagine, as you travel to Orion, explore the night sky and study the birth, life and death of stars.

The course

You can get more of an idea about what’s covered in the course from this short summary.

In Week 1, you’ll discover the constellation of Orion, find it in the sky and find out how the constellations can be used for navigation.

In Week 2, learn about the lifecycle of different types of star, their birth and what happens when they die. Find out about nuclear fusion that happens inside a star and how their mass, luminosity and temperature are related to their lifecycle.

In Week 3, investigate what the night sky can reveal about how it all began, learn about different types of telescopes and go behind the scenes with Monica Grady.

In Week 4, consider how planets and planetary systems formed and find out about our place in the Universe. You’ll also find out about exoplanets and consider whether other stars have planets like ours.

The course is designed to run on desktops, tablets and mobile devices; however, some of the material is quite detailed and using a larger screen will enhance your experience. Materials are best viewed running the most up-to-date software available for your device and using the most recent version of the web browser.
