Since the dawn of civilisation as we know it, humans have been looking to the skies, to gain an understanding of our collective past, and learn something about our future.

Estimated to have appeared around 200m years after the events of the big bang, the first stars of the universe suddenly came into being, shedding light in the darkness. These stars produced the essential building blocks for entire galaxies, for planets, and for the creation of life in the universe.

In this fascinating masterclass with Dr Emma Chapman, the author of First Light: Switching on Stars at the Dawn of Time, she will attempt to fill in the missing first one billion years from the timeline of the universe, by revealing more about the earliest stars – how they were formed and why they were so unusual.

Emma will also discuss recent discoveries in astrophysics, including what the James Webb space telescope is revealing to us about the origins of the universe, and what the next big missions in space exploration will be.
