Overview

Since the earliest days of astronomy, since the time of Galileo, astronomers have shared a single goal — to see more, see farther, see deeper. Hubble's discoveries have transformed the way scientists look at the universe. Its ability to show the universe in unprecedented detail has turned astronomical conjectures into concrete certainties. Hubble has gifted us with more than scientific facts: it has shown us the stunning art portrayed on a massive scale across our heavens. From the spectacular shapes, colors and images of Nebula to the dazzling variety of galaxies and the strange anomalies scattered throughout the heavens, Hubble has captured images that inspire our imaginations.
This is a collection of the Hubble Space Telescopes most significant and inspiring discoveries regarding the creation and significance of quasars with commentary explaining their importance. The book begins with an essay on the history and significance of the Hubble Telescope and then continues with an extensive description of the science and theory behind quasars. The magnificent, full color images are best viewed on a color e-book platform. Over 25 photos and illustrations.
