If you want to know all the things we know or guess about the sun, this is definitely the book for you. Lucie Green isn’t just a science communicator — she’s actually doing the research, so she knows what the current questions are, what the latest research is, and all the history of how we came to know what we know. Her enthusiasm is plain throughout, and she does a good job of describing both the actual physical events of the sun, and the sensation of observing and understanding them.
If you’re not hugely into physics, you might find that a few chapters do start to drag. But for the most part, it’s a fascinating book — and there’s a lot of stuff I didn’t know.
