Understanding the night sky

You don’t need complicated maths or even a sextant to enjoy the night sky and use it for navigation, says William Thomson

Understanding the night sky

One of my most prized possessions is a book, The History of Seafaring, Navigating the World’s Oceans, by the American sailor Donald S. Johnson. A treasure trove of priceless knowledge, the story shares our progression in wayfinding since humans first clambered into hollowed-out tree trunks thousands of years ago, and it has taught me that although celestial navigation is ancient, it is also timeless and equally practical today as it was in the days of Captain Cook.

While you could argue that universal access to global positioning satellites, atomic clocks and precision compasses has made celestial navigation irrelevant, another school of thought says there has never been a better time to learn astronavigation, because we can constantly check our results. And by no longer needing to rely on time-consuming methods like a noon sight to calculate our position, we can disregard antiquated techniques and develop a new system that works in symbiosis with modern technology, enriching our experiences. The purpose of this series is to explore how, sharing the techniques I’ve tested frequently on passages with my partner Naomi and our children Ottilie and Arva.
