Hubble Focus: Galaxies through Space and Time

Hubble Focus is a series of e-books that dive deeper into specific fields of astronomy that have been forever changed by Hubble’s explorations. Hubble Focus: Galaxies through Space and Time is the second book in the series, describing some of Hubble’s recent discoveries about galaxies — the homes of stars, nebulas and planets — from our own Milky Way to the most distant galaxies ever seen. These discoveries are helping us understand how galaxies evolve and how the universe itself has come to be the way it is today.
