Edwin Hubble and the Origins of the Universe

If learning about the origin of the universe wasn’t enticing enough, this title guides readers through the trials of its discovery by Edwin Hubble, after whom the Hubble space telescope is named. Chronicling Hubble’s early years at the University of Chicago, to his discovery of spiral nebulae, to his later research into the expanding universe, readers experience Hubble’s successes and failures in the discovery of the Big Bang. This title can serve as inspiration to young people interested in science to never stop dreaming big and sometimes, as in Hubble’s case, dreaming as big as the universe.
