The Listeners


James E. Gunn - 1972
    In 2025, a Message from Capella was received! And suddenly, Robert MacDonald, Project Director, faced one of mankind's greatest challenges. He had to find a way to decipher a communication from a totally alien culture...and then persuade a reluctant world to respond.

The Pandora Directive


Aaron Conners - 1995
    The official story was that the Roswell crash was a balloon. But the real story is that Project Bluebook became Project Blueprint and helped start WWIII. Tex Murphy has never been good at staying out of trouble . . . and this time he's in for lots of trouble

As on a Darkling Plain


Ben Bova - 1972
    Earthlings are sent to Saturn's largest moon to investigate machines that were left behind centuries ago by an alien race.

Cosmos: Possible Worlds


Ann Druyan - 2019
    From the emergence of life at deep-sea vents to solar-powered starships sailing through the galaxy, from the Big Bang to the intricacies of intelligence in many life forms, acclaimed author Ann Druyan documents where humanity has been and where it is going, using her unique gift of bringing complex scientific concepts to life. With evocative photographs and vivid illustrations, she recounts momentous discoveries, from the Voyager missions in which she and her husband, Carl Sagan, participated to Cassini-Huygens's recent insights into Saturn's moons. This breathtaking sequel to Sagan's masterpiece explains how we humans can glean a new understanding of consciousness here on Earth and out in the cosmos--again reminding us that our planet is a pale blue dot in an immense universe of possibility.

Overkill


Robert Buettner - 2011
    Then Jazen learns that the stakes are not merely his own life, but the fate of an entire alien race. “Buettner goes well beyond . . . military science fiction . . . he understands . . . living as a soldier—the boredom punctuated by terror, the constant anxiety and self-doubt, the random chaos that battle always is, and the emotional glue that holds together people who may have nothing in common except absolute responsibility for one another's lives.” —Joe Haldeman, Hugo and Nebula Award-winning author“[O]nce in a while . . . a contemporary author penetrates to the heart of Heinlein's vision . . . to replicate the master's effects. . . . [O]ne such book [is] Robert Buettner's Orphanage.” —The Washington Post“Entertaining. Buettner shows the Heinlein touch.” —Denver Post

The Void


Frank Close - 2007
    Readers will find an enlightening history of the vacuum: how the efforts to make a better vacuum led to the discovery of the electron; the understanding that the vacuum is filled with fields; the ideas of Newton, Mach, and Einstein on the nature of space and time; the mysterious aether and how Einstein did away with it; and the latest ideas that the vacuum is filled with the Higgs field. The story ranges from the absolute zero of temperature and the seething vacuum of virtual particles and anti-particles that fills space, to the extreme heat and energy of the early universe. It compares the ways that substances change from gas to liquid and solid with the way that the vacuum of our universe has changed as the temperature dropped following the Big Bang. It covers modern ideas that there may be more dimensions to the void than those that we currently are aware of and even that our universe is but one in a multiverse. The Void takes us inside a field of science that may ultimately provide answers to some of cosmology's most fundamental questions: what lies outside the universe, and, if there was once nothing, then how did the universe begin?
