Are we alone in the universe ? It’s a fundamental question for Earth-dwelling humankind. Are there other worlds like ours, out there somewhere ? In "Hidden in the Heavens", Jason Steffen, a former scientist on NASA’s Kepler mission, describes how that mission searched for planets orbiting Sun-like stars—especially Earth-like planets circulating in Earth-like orbits. What the Kepler space telescope found, Steffen reports, contradicted centuries of theoretical and observational work and transformed our understanding of planets, planetary systems, and the stars they orbit. Kepler discovered thousands of planets orbiting distant stars - a bewildering variety of celestial bodies, including rocky planets being vaporized by the intense heat of their host star; super-Earths and sub-Neptunes, with properties simultaneously similar to and different from both Earth and Neptune ; gas giants several times the size and mass of Jupiter; and planets orbiting in stellar systems that had only been imagined in science fiction. It was, Steffen says, the opportunity of a lifetime to work in the most exciting scientific field on the most awe-inspiring mission. He offers a unique, inside account of the work of the Kepler science team (and the sometimes chaotic interactions among team members), mapping the progress of the mission from the launch of the rocket that carried Kepler into space to the revelations of the data that began to flow to the supercomputer back at NASA - evidence of strange new worlds unlike anything found in our own solar system.

The Hubble Space Telescope is one of the most important scientific and engineering endeavors of our time. It has given humankind the first truly clear view of the heavens and has revolutionized almost every area of modern astronomy. The author of this text, David Leckrone, worked as a project scientist on Hubble for 33 years. From 1992-2009 he was the Senior Project Scientist for Hubble at NASA's Goddard Space Flight Center. In that role he had an insider's view of the trials and triumphs of the Hubble mission, including its extraordinary scientific discoveries and the personal journeys of the astronomers who made them, the adventure of five successful shuttle-based servicing missions, and the quiet heroism of the many scientists, engineers and managers who rose to the occasion when Hubble was in trouble. This book is loosely a personal memoir but can more accurately be called a "Hubble family memoir" for which Leckrone serves as narrator.Based on numerous interviews and personal observations, Life With Hubble tells the human stories and describes the professional achievements of scores of talented and dedicated individuals who made major contributions to the Hubble legacy. It spans the years from 1990, when Hubble was launched and when the affliction of spherical aberration was discovered in its optics, through the final servicing mission in 2009 and up to the present day. There are also numerous flashbacks from earlier years. This book is aimed at an informed, non-professional audience, including those who have followed the saga of Hubble throughout its lifetime.
