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.

What is the sun really made of?
How hot is it on the inside?
And will it ever run out?
Let solar physicist Professor Lucie Green take you on a journey to discover what the sun is, how it works and why we are only now discovering how it explains some of our universe's greatest mysteries. Along the way we will meet Galileo, Halley, Newton and a host of other explorers who teased out the sun's secrets from a distance of 90 million miles.
The story of the sun is our story - of how a giant ball of light and heat made all life on Earth.
Packed full of fascinating facts and exciting discoveries about our home star, 15 Million Degrees is a book brimming with brilliance - just like the sun.
'Comprehensive, wide-ranging. Green's passionate enthusiasm shines through on every page. An engaging, personal insight into contemporary solar research. An outstanding and eminently readable book' Astronomy Now

This book takes a fascinating look at a literally brilliant subject... one of the most enjoyable books about science you could hope to find
Thrilling ... Lucie Green's huge enthusiasm for the Sun is apparent throughout
Green, a solar physicist at University College London, is an engaging and careful companion. She is clearly enamoured of her subject and keen to acknowledge those who have gone before her ... Reading this book confirms what I felt as a student: that truly understanding the Sun is as much about philosophy as it is about physics
Green's enthusiasm for her subject is infectious ... [a] fine book
The author's passionate enthusiasm for her subject shines through on every page ... an outstanding and eminently readable book which conveys a remarkably comprehensive and wide-ranging account of our nearest star
Professor Green has been studying the sun for 20 years and her passion for her 'favourite star' burns from every page
