It delivers the food we eat, the air we breathe, the clothes we wear. We read by its light — on a screen, on paper, indoors or out — because it is the ultimate energy source: indeed, the only energy source. It powered the primeval forests of carboniferous ferns and conifers that became our fossil fuel just as it drives the winds for the electrical turbines that must one day replace coal and oil. Even the radioactive elements whose decay and fission keep the planet alive and self-renewing are stellar confections: fragments first forged in, and then recycled by supernovae, exploding giant suns. In fact, it is the only thing in the solar system that really works hard: every second it converts m tonnes of hydrogen to m tonnes of helium and those missing 4m tonnes become the energy released by the thermonuclear reaction: a bonus of electromagnetic radiation distributed across the entire solar system. A trifling 2 billionth of this highlights one side of the spinning Earth, delivering energy at the rate of 1, joules per square 15 Million Degrees: A Journey to the Centre of the Sun. But this planetary nourishment arrives every second to every square metre and from this shining moment all else follows: everything that has ever lived, every evolutionary advance, every human conceit, every sensory pleasure, and every book, including this one. But the light that hits the page — in this story of research in progress — seems a strangely haphazard agency. In this vast furnace, 15m C at its core, the highly improbable can happen: just give it time. Protons collide and, once every bn collisions, overcome their resistance to each other, perform a complex three-step dance of union, and become a helium-3 nucleus, releasing two neutrinos and two gamma ray 15 Million Degrees: A Journey to the Centre of the Sun in the process. But the real thrill is in the incomplete unfolding story: of the puzzles set by coronal mass ejections, those great million-mile-an-hour blasts of stellar fabric that light up the aurorae, pound spacecraft and once, inset telegraph equipment ablaze. And, in the next two years, the European Space Agency and Nasa will each launch a space mission to observe the making of the solar wind, while Voyager 1 and 2 are still feebly relaying signals from the furthest edge.

If you want 15 Million Degrees: A Journey to the Centre of the Sun know all the things we know or guess about the sun, this is definitely the book for you. 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. Reviewed for The Bibliophibian. From the first tentative steps taken by humans to fathom it's own star to the details of inner workings and the tremendous reach of the solar atmosphere has been covered in easy conversational style. The description of difficult concepts like magnetic field reconnection have been deftly handled using easy to understand analogies. The tale has 15 Million Degrees: A Journey to the Centre of the Sun a personal touches and the author has been able to communicate her enthusiasm for this very specialised subject strongly. It is probably the only non-academic book dealing exclusively with the Sun. A must read for everybody interested in science writings and the state of knowledge about solar physics. Lots of details are lost without colour. I'd to switch to my android tablet from Kindle paperwhite midway. There 15 Million Degrees: A Journey to the Centre of the Sun a lot to learn about our Star. This book provides an amazing insight for our Sun. Highly recommended for everyone who evolved and constantly get nourishing from the prime source of all the form energy on this planet. As an amateur astronomer with a large computer controlled astro scope, Lucie Green's book has inspired me to utilise my optics to view our star in hydrogen alpha wavelengths. Living on the misty twisty moors of northern England where the night sky is often obscured by clouds, turning my observing to day time may well be productive. For the casual reader who wishes to take Lucie's 'journey to the centre of the sun' I'm sure that they will n '15 Million Degrees' is a cool book on a red hot subject. For the casual reader who wishes to take Lucie's 'journey to the centre of the sun' I'm sure that they will not be totally blinded by science. Admittedly there are sections of this book that cover magnetic helicity and flux ropes that I had to take in small bites, but generally for all things solar this 15 Million Degrees: A Journey to the Centre of the Sun provides a fully comprehensive, fact packed, and intelligently explained up to date study of the complex dynamics of our sun. Jul 16, Andrew Grenfell rated it it was amazing. Our whole world literally revolves around it. Many religions have worshiped it, probably for 10's of thousands of years. Any inquiring mind must at some point have wondered how it works, surely? This book delves into the mysteries of our solar system's chief source of power. A great overview of the topic for those inquiring minds that wanted to scratch the surface a little. You don't need a knowledge of plasma physics or magnetic interactions. But, it is pitched at a level where those ideas are Our whole world literally revolves around it. But, it is pitched at a level where those ideas are just out of reach. Thoroughly recommended for any general interest science reader or anyone with an early interest in astronomy or astrophysics. Mar 05, Amy Suzanna rated it really liked it Shelves: non-fiction. Isn't the sun just fascinating? We only exist on this planet because we happen to be the perfect distance away from the sun. I've never really known vast amounts about our star, but I do 15 Million Degrees: A Journey to the Centre of the Sun. Green's book can be hard to follow at times simply because the things she's describing are so difficult to visualise and comprehend that it fails to make sense. However, this book is well written enough that after rereading some chapters several times, I finally got there and I feel I can understand a bit o Isn't the sun just fascinating? However, this book is well written enough that after rereading some chapters several times, I finally got there and I feel I can understand a bit of Green's love for the sun. I can certainly see why someone might devote their entire career to trying to unlock its secrets. Definitely a book worth persevering through! The authors passion for the subject was clear, and it was mainly easily understood, but got a bit bogged down in magnetic fields, which are a bit unclear to the uninitiated, though an important part given the subject matter, but an interesting read nonetheless, and one that told me things other science books hadn't, which is all you can ask for. Nov 18, Dan Cohen rated it liked it Shelves: science-and-maths. An entertaining and informative read. I found the tone a bit too light overall, although, conversely, the sections where the author gets into details of how the magnetic field of the sun works were difficult. For me, I'd have liked a bit more on the fusion processes, especially on how these are expected to progress through the later stages of the sun's life. I enjoyed this book. Lucy's writing style is easy to read. She managed to discuss complex topics in an informative simple way. I liked the number of useful diagrams. The book meandered over many topics relating to the Sun and gave good insight into how science is done. Well worth a read. Jun 01, Julian Onions rated it really liked it Shelves: science. Pretty good - especially if you like magnetism! I spotted a couple of minor errors, but nothing too upsetting, and I bet no one else would spot them. View 1 comment. May 30, Justin rated it really liked it. This was a really interesting and accessible guide to the Sun and its workings. I've found the clear scientific explanations to be a really helpful complement to my undergraduate astronomy course. Green also weaves in the history of discoveries about the Sun. Very well written with a style that is as bright as the subject itself. I like the stories that Lucie Green uses to reveal the science behind our star. Very well written, and interesting. It does what it says on the cover. It is about the sun, and the history of our understanding of it. Sep 10, Derek Henderson rated it liked it. Start well with enthralling details and an engaging style.
