This book tells the story of the Cosmic Dawn and Epoch of Reionisation: the time when the very first stars burst into life. These bodies were hundreds of times the size of the Sun and a million times more luminous, lonely blue giants that lived fast and died young in gigantic explosions, seeding the Universe with the heavy elements fundamental to the construction of galaxies, planets and eventually life itself.
Astrophysicist Dr Emma Chapman tells how these stars formed, why they were so unusual, and what they can teach us about the Universe today. She also offers readers a first-hand look at the telescopes currently being developed to take this period in the Universe’s history from the realm of theoretical physics towards the wonder of observational astronomy.
