The astrophysicist Neil deGrasse Tyson has attracted one of the largest followings online in the world, thanks to the contagious way in which he talks about science and our universe. His bestseller Astrophysics for Young People in a Hurry (2017) provided more than a million readers with a concise and accessible understanding of the universe.

Now Tyson reveals to us his correspondence with people from around the world who approached him seeking answers to small or big questions about science, faith, philosophy, life, and – of course – Pluto. His insightful, enthusiastic, and often humorous responses reflect his popularity and his ability to teach us about the secrets of the universe in an understandable way.

His most sincere and heartfelt work to date, Letters from an Astrophysicist, introduces us to a new, personal dimension of his quest regarding our place in the universe.
