From the discovery of entirely new kinds of galaxies to a window into cosmic ‘prehistory', Bothwell shows us the Universe as we've never seen it before – literally.Since the dawn of our species, people all over the world have gazed in awe at the night sky. But for all the beauty and wonder of the stars, when we look with just our eyes we are seeing and appreciating only a tiny fraction of the Universe. What does the cosmos have in store for us beyond the phenomena we can see, from black holes to supernovas? How different does the invisible Universe look from the home we thought we knew? Dr Matt Bothwell takes us on a journey through the full spectrum of light and beyond, revealing what we have learned about the mysteries of the Universe.This book is a guide to the ninety-nine per cent of cosmic reality we can't see – the Universe that is hidden, right in front of our eyes. It is also the endpoint of a scientific detective story thousands of years in the telling. It is a tour through our Invisible Universe.‘Matt Bothwell guides us through the world of astronomy and astrophysics with an engagingly written, up-to-date view of some of the key current frontiers. He opens our eyes to wavelengths beyond the light we can see. His journey includes galaxies, black holes, star formation, dust, gravitational waves, dark matter and dark energy – all with interesting historical context, accessible explanations and richly peppered with accurate analogies.
