An essential companion for anyone wanting to discover the latest images from the James Webb Space Telescope and what these discoveries mean for our universe – and our understanding of human history.
Can the James Webb Space Telescope really see the past? Pioneering space experts Maggie Aderin, PhD, and Sarah Wild take readers on a journey back in time to explore the creation and formation of our solar system, galaxies, and other exoplanetary systems in the universe.
Beginning in our own galaxy, this stunning book uses the James Webb’s cinematic images as route markers towards this cosmic dawn, revealing the mesmerizing pictures’ secrets and explaining the scientific phenomena within them. Along the way, it explores some of cosmology’s greatest mysteries, such as the shape of the universe, the nature of dark matter, and whether there is other life in the cosmos.
Featuring mind-blowingly detailed images from NASA’s telescope, Maggie Aderin, PhD, and Sarah Wild demystify the pictures from deep space and explain the essential science behind each discovery. James Webb’s Ancient Cosmos explores not only the origins of the universe but also the evolution of scientific knowledge and humanity’s future.
"This book is literally heavenly – a wonderful showcase for the glories of the cosmos revealed by the extraordinary James Webb Space Telescope." - Marcus Chown, Author of One Thing You Need to Know
"Maggie Aderin adds a depth of understanding that is rarely found in illustrated books. A collection of wonders." - Brian Clegg, Science Writer
"The ultimate book on all things JWST, perfectly blending astrophysics and engineering. Aderin describes not just the science of what’s going on in these incredible JWST images but crucially how the images were taken." - Dr Becky Smethurst, Astrophysicist, Author, and YouTuber
"Dr Maggie Aderin offers a stunning insight into the incredible galaxies that surround us." - Sandi Toksvig
