Neil deGrasse Tyson
Sagan profoundly influenced the lovable astrophysicist Neil deGrasse Tyson, and in many ways, Tyson has become Sagan's heir. Indeed, Tyson will even be hosting a new version of Sagan's landmark show Cosmos, to be released in 2014. While their subject matter is almost entirely the same, they have distinct approaches to writing about science. Sagan had a much more lyrical and wry style, whereas Tyson is an excitable child at heart, and uses his enthusiasm and energy to engage his audience with his work. His 2012 book Space Chronicles, on the importance of NASA in the 21st Century, is a must-read, as is his zany Merlin's Tour of the Universe.
