110 times wider than Earth; 15 million degrees at its core; an atmosphere so huge that Earth is actually within it: come and meet the star of our solar system
Light takes eight minutes to reach Earth from the surface of the Sun. But its journey within the Sun takes hundreds of thousands of years. What is going on in there? What are light and heat? How does the Sun produce them and how on earth did scientists discover this?
In this astonishing and enlightening adventure, you'll travel millions of miles from inside the Sun to its surface and to Earth, where the light at the end of its journey is allowing you to read right now. You'll discover how the Sun works (including what it sounds like), the latest research in solar physics and how a solar storm could threaten everything we know. And you'll meet the groundbreaking scientists, including the author, who pieced this extraordinary story together.
How we describe the condition of our books
We are very proud of the condition of the books we sell (please read our testimonials to find out more!)
New: Exactly as it says.
As New: Pretty much new but shows small signs of having been read; inside it will be clean without any inscriptions or stamps; might contain a remainder mark.
Very Good: Might have some creases on the spine; no hard cracks; maybe slight forward lean and short inscription inside; perhaps very minor bumping on the corners of the book; inside clean but the page edges might be slightly yellowed.
Good: A few creases on the spine, perhaps a forward lean, bumping on corners or shelfwear; maybe an inscription inside or some shelfwear or a small tear or two on the dustjacket; inside but page edges might be somewhat yellowed.
Fair: In overall good condition, might have a severe forward lean to the spine, an inscription, bumping to corners; one or two folds on the covers and yellowed pages; in exceptional cases these books might contain some library stamps and stickers or have neat sticky tape which was used to fix a short, closed tear.
Poor: We rarely sell poor condition books, unless the books are in demand and difficult to find in a better condition. Poor condition books are still perfect for a good read, all pages will be intact and none threatening to fall out; most probably a reading copy only.
