Institute of Astronomy - Public

What would you like to know?

You ask. We answer. We're a team of Cambridge Ph.D. students covering a wide range of areas across astronomy. Ask us anything! (Except homework questions, we can't answer those.) All ages very welcome, and no matter the question, however simple or complex!

We post answers to questions every week! They're are a mix of written (with images) and video answers (see our playlist on the Cambridge University Astronomy YouTube channel -- coming soon!), and we give them at the level of background knowledge you request. Plus we always include links to places where you can learn more about the topic!

So, what would you like to know?
