Drop by and chat with our Observatory Explainers who are bringing the history of astronomy to life.

Enjoy a range of public talks and activities delivered by our Observatory Explainers, ranging from short talks on the hidden stories of the Royal Observatory, Greenwich, to solar observing and hands on science demonstrations.

Our team of Observatory Explainers can answer your burning questions about astronomy such as: why do we need dark matter to explain the universe and how do astronomers know that space is expanding?

Also, if you've always wondered what is involved in modern astronomy research compared to the historic research that took place at the Royal Observatory, then they are the people to ask.
