Thank you to John for this wonderful story about navigating at sea using the stars and a sextant.
Celestial navigation is an art and a science, that has been used by navigators since ancient times. Interestingly, it is still a skill that can come in handy at sea. If your GPS ever fails the stars are always there as a back up, just so long as you can catch a glimpse of them through the clouds!
This animation is part of the Stargazers project for which I am collecting stories about stars. If you have a story that you would like to share with me then please get in touch!
