Young Astronomers Workshop

Get hands-on in these short drop-in family workshops themed around space science and exploration, from the most recent discoveries about the Solar System to our latest understanding of the wider Universe.

Our team of Observatory Explainers include those who are studying Astrophysics at degree or postgraduate level and can answer your burning questions about astronomy. How big IS the Universe? Why is Pluto not a planet anymore? Also, if you've always wondered what it takes to become an astronomer, then they are the people to ask! 

Suitable for ages 4+. This activity will run on weekends from 11-14.30.
