If you have never heard of the Herschels, then you are missing out on the most important astronomers of the 18 th and 19 th Century. William Herschel, discoverer of Uranus, together with his able and dedicated sister Caroline and his erudite son John revealed the Milky Way and its diverse contents as never before. Through careful visual observations with their giant telescopes, this dynastic dynamo bore witness to a multitude of dancing double stars, incandescent nebulae, and the Milky Way itself. Today, we inherit from them the picture of a disk-like galaxy which contains our Solar System and countless other stellar systems. This book review by Endicott College student Todd Stelling provides a fine introduction to Michael Lemonick’s lively portrait of the Herschels and their cosmic discoveries.
