The Sun Our Amazing Star

Blast off and explore the star of our solar system—the Sun! Billions of stars fill the universe. But for humans, the most important star is the one closest to Earth—the Sun. From vitamin D to solar energy, the Sun provides the power necessary to sustain life on our planet. And as the center of our solar system, the strong gravitational pull from this ball of burning gas keeps all the planets in orbit. Discover the significance of the Sun and its brilliant blaze in this fascinating book!

Our sun is one star among 50 billion in the galaxy. Our galaxy is only one among 50 billion in the universe. With a vastness this incomprehensible, it is easy to feel like we are mere specks of sand on an endless shore. But our sun is special. Though roughly 150 million kilometers separate us, we could not be more connected. Literally, everything you see comes from the sun. The words you are reading now are really photons that left the sun about 8 minutes ago only to bounce off this page and into your eyes. We owe our very existence to our sun. It provides just enough heat to keep our fragile bodies from freezing to ice or burning to a crisp. Every bite of food we eat we owe to the sun, whose energy is converted into plants that provide sustenance for everything up the food chain. DIV/divDIVWe have understood the sun’s importance for millennia. The earliest humans, awestruck by its blazing splendor, left drawings of the sun on cave walls. Nearly every civilization, no matter where it sprang up on the planet, has revered the sun. Myths about the sun were the basis of the earliest deities of ancient Sumerian, Hindu, Egyptian, Chinese, and Meso-American cultures. Before Apollo, the ancient Greeks worshiped the sun-god Ares. Before Zeus, the ancient Romans worshiped Sol./divDIV/divDIVThroughout our history, the sun has been central to humanity’s quest for meaning in the universe. But our history has been a brief moment in our sun’s 4.5 billion year life. Only recently, through advances in science and technology, have we begun to understand our sun - where it came from, how it functions, how it affects our lives and how it eventually will destroy our planet./divDIV/divDIVOur Sun is a comprehensive, easy-to-understand guide to everything we know about our closest star. Illustrated with stunning pictures from NASA’s newly-launched Solar Dynamics Observatory, Our Sun will reveal the science behind the sun, trace its impact on human history, and reveal its growing importance to our future way of life./div

A fascinating and comprehensive guide to the sun - our home star - which remains the greatest mystery in the solar system, and why understanding it is pivotal to our future existence here on Earth. In 1869, a great mystery was born. As astronomers observed a total solar eclipse, for the first time they saw the faint glow of the solar corona, the sun's outer atmosphere. Measurements of a previously unknown wavelength that made up this solar light sparked hot debate among scientists, but it was another sixty years before they discovered that this wavelength was in fact iron being burned at a staggering 3 million degrees Celsius. With the sun's surface only 6,000 degrees, this shouldn't be possible. What we now knew about the sun appeared to defy the laws of physics - and nature. But as well as being shrouded in intriguing mystery, the unpredictable nature of the sun's corona poses a serious threat to our life here on earth - the destructive potential of solar storms, caused by solar material travelling out into space at around 1 million miles an hour, is huge. Remaining beyond our reach until now, a new generation of ambitious solar missions are currently travelling closer to the sun than any previous spacecraft in history. As we enter this unprecedented era of heliophysics, there has never been a better time to get to grips with the workings of our home star.

Introduces the sun, its physical characteristics, and the history of human observation of the sun.

#1 New York Times bestselling author Nicola Yoon is back with her second book, and just like Everything, Everything, it's an instant classic with a love story that's just as intense as Maddy and Olly's--get ready for Natasha and Daniel.
