Discover hidden secrets about the Sun, our local star, and learn about eclipses and the Northern LightsThe Sun is incredibly dynamic and shrouded in mystery, despite its apparent unchanging appearance in our daytime sky. In this fascinating guide, you will explore the history, science and modern observations that uncover the mysteries of the Sun.From ancient astronomers who hailed the Sun as a deity, to new age space exploration, the way we observe the Sun has come a long way. Humanity’s scientific journey to understand the Sun has included many intriguing and humorous tales from over the centuries. In today’s age, it is far easier to become a sun observer.• Learn how our knowledge of the Sun has evolved over centuries• Understand the basic physics behind sunspots and solar flares• Wonder at the life and death of stars like the Sun• Discover how solar activity affects us here on Earth, what are solar weather and solar radiation?• Solar and lunar eclipses: why, where and when do these occur?• Access tools and methods to observe the Sun safely from your own back garden• Learn about cutting-edge space observations of the Sun and how to access these images• Illustrated with key imagery from solar telescopes, NASA and ESA

BBC Sky at Night Magazine "Essential reading for anyone desperate for some facts and probabilities about actual threats to Earth in the age of the cosmically ill-informed." Forbes “For anyone looking for an engaging and trustworthy guide to our place in a constantly shifting cosmos, Space Hazards is a rewarding read, a clear and reassuring guide to the real cosmic risks that matter and the ones that do not.” AstrobitesOn Earth we are surrounded by an array of potentially dangerous phenomena within our solar system and beyond. Thankfully, none pose an immediate threat to life, but it is crucial for scientists worldwide to continuously monitor their presence, assess potential risks, and develop strategies to mitigate them. Discover the science behind seen and unseen threats from spaceConsider the likelihood of their potential catastrophic impact on our planetWhat dangers do we face from asteroids and near-Earth objects?How does space weather affect us here on Earth?Is there a plan to the challenge of multiple space debris?Do the cosmic effects of stellar and black hole collisions impact us?This comprehensive overview offers us a compelling look at the dynamic and sometimes dangerous environment surrounding Earth, highlighting the importance of ongoing research and preparedness in safeguarding the future of our planet.

Topics covered include asteroids and near-Earth objects, space weather events, Earth's magnetic polarity flips, the growing challenge of space debris, and the cosmic effects of stellar and black hole collisions.This comprehensive overview offers us a compelling look at the dynamic and sometimes dangerous environment surrounding Earth, highlighting the importance of ongoing research and preparedness in safeguarding the future of our planet.

What strange new worlds lie unseen in the deep cosmos? View images never before seen in print Discover unimaginable wonders in an extraordinarily beautiful collection of cosmic imagery bursting with colour, made possible by groundbreaking observatories and instruments which have expanded visibility of the universe beyond the limits of the human eye.Did you know that there are strange radio waves permeating the entire Universe, and cataclysmic x-rays bursting out in the Milky Way’s spiral arms? Delight in these spectacular sights for the first time in this visually arresting and colourful space book, where astronomical artworks – an awe-inspiring feast for the eyes – are demystified by experts.Visible light makes up a small fraction of the radiation we receive from space, and the demand for discovery has driven technological advances that allow astronomers to observe everything from the hum of young stars sending radio waves across the Galaxy, to intense bursts of gamma radiation released by energetic events beyond imagination.As a result, a dizzying variety of strange and wonderful images have been produced, some of which combine multiple forms of light to illuminate invisible details and unlock scientific secrets about the sky.

Across the centuries, and across the world, solar and lunar eclipses have captured the human imagination. Weaving together their long history and mythology with the very latest scientific techniques and discoveries, Philip's Little Book of Eclipses is a global guide to their locations and significance over the coming decades.Each year, several eclipses can be seen around the world, grabbing headlines and drawing tens of millions of curious sky-watchers to travel and observe them. Philip's Little Book of Eclipses maps the locations of both lunar and solar eclipses over the next decade and explains where and how to view and photograph these extraordinary phenomena. An excellent solar eclipse is due in Europe in August 2026 - 90% in the UK, Ireland and France, and total in Iceland, Portugal and much of Spain - and excitement around the world is mounting. A popular science guide, this evergreen book covers the history, mysteries, secrets, discoveries and experiences of chasing eclipses - uniquely of both the Moon and the Sun. They are among the greatest spectacles in the sky, and to astronomers they hold a great deal of value for the study of the Sun, Moon and Earth itself. Readers will explore eclipse-science in an accessible way, suitable for the beginner, then find themselves with all the advice they need to predict and safely view eclipses, as well as produce their own stunning photographs.Highlights include: * Locations and description of the lunar and solar eclipses around the world over the next decade - so you can plan your travels early * Accessible scientific explanations of the natural phenomena with key elements to watch for * The best ways to observe the eclipses of the Moon and Sun safely* How to photograph the events to create outstanding images * The history and mythology of the impact of eclipses over the last six thousand years
