Afterglow: Dispatches from the Birth of the Universe

Cosmology is the one field in which researchers can—literally—witness the past. The cosmic background radiation, ancient light streaming toward us since the Big Bang, provides a pristine window onto the birth and evolution of the universe. Already, the radiation has been key to confirming an early explosive expansion of space, determining the geometric shape of the universe and identifying seeds that resulted in galaxies. Now, the cosmic background radiation is poised to reveal when the first stars formed, what happened in the fraction of a second after the Big Bang, and the answers to a host of other bold questions about the cosmos. Join Nobel Laureate John Mather and other leading scientists who are leading the way.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.
