The darkness of the night represents something unknowable – even frightening – to many. But when we really look up and into it, we can find celestial light shows, whole ecosystems, and, perhaps, a new perspective. The night sky offers something essential – a connection to something bigger than ourselves that can, in turn, help us understand ourselves and each other better. Humans have recognised and tried to make sense of this feeling since ancient times. For so many – from physicists and astronauts to astrologists and artists - the night sky has been a source of inspiration, wonder and exploration. But now our relationship to dark skies is changing as our access to them is depleted. Light pollution all over Earth can be seen from space, altering the landscape and outlining the coasts. And if we look from Earth into space, we can see artificial light there, too. In this short volume, Anna Levin looks at how we can learn from and nurture our relationship with the night sky even and especially in the context of our changing world. As you learn how to see and treasure the night sky, a sense of wonder about the universe will help you to understand more about our own pale blue dot.
