The Sun

Opis od wydawcy

Astronomer Brendan Owens examines the features and processes at work in the Sun, revealing the interconnected sciences involved in finding out more about it and the practical importance of doing so for our modern world. It's a slow-burn tale of scientific discovery!

An enthralling exploration of the star on our doorstep, charting the journey from ancient superstition to the deep scientific mysteries yet to be resolved. The Sun examines how we've come to understand the features and processes at work in our star, starting with the earliest observations of mysterious sunspots and ending with the rich and complex investigation of the connected Sun-Earth system.

The enormous significance of the Sun to our lives has been felt ever since ominous eclipses and mysterious sunspots were observed many thousands of years ago. Scientists and astronomers from many different fields have contributed over the centuries to the rich knowledge we have of the Sun and its relationship with the Earth. What is the Sun made of? What is the solar wind? What could magnetism have to do with the Sun? How have scientists made these discoveries, and what does it all mean for us here on Earth? And what of the deep scientific mysteries that remain unresolved? Understanding our closest star has never been more important.
