Book Description
Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.

Book Description
On the Damned World, it's every man for himself. Only it's not just mankind who dwells here . . . The Earth of the future is not one you'd recognize. Creatures previously thought to be simply myth- vampires, two-legged dragons, abominable snowmen, and nine other races-have overrun the planet and made it their own. Humanity is nearly extinct. But now the Twelve Races have discovered that their own fortunes are inextricably linked with the remnants of the human race. And so one of the last remaining humans, a young slave girl named Jepp (who holds the key to the future of the world), is on her way to a fateful meeting with the most powerful creature on the face of the planet. Except the question isn't what will happen when she gets there . . . but if she's going to make it there alive.

Book Description
The first spacecraft to explore the secrets of the Sun, Jupiter, Saturn, and the void beyond Pluto, the Pioneer space probes have been the trailblazers of the space age, truly going where no man has gone before. Emblazoned with the nude figures of a man and a woman, etched representations of our human form, the Pioneer generation of probes were aptly named. Launched into the inky depths of space, they were more than mere machines, they were humanity's first emissaries into deep space. And the pictorial inscriptions that adorned the crafts embodied the hopes and dreams of everyone involved in the Pioneer program. They were our humble attempt to communicate with the extraterrestrial intelligent life we imagined the probes might encounter -- they were our message in a bottle. Perhaps the most efficient, reliable, and cost effective program to come out of NASA, the Pioneer missions are a shining example of how a small and talented group of people can, against all odds, pull something off that has never been done before. Indeed, more than thirty years after its launch in 1972, Pioneer 10 is still cruising into interstellar space, sending back data as it courses through the galaxy while Pioneer 6, in solar orbit, is more than 35 years old and humankind's oldest functioning spacecraft. But despite their enduring contributions, the Pioneer project remains a footnote in space history, little more than a humble prologue to its inheritors. The Depths of Space recounts the long overdue history of Pioneer both as a scientific and technological achievement and as the story of the exceptional people who made the program possible. This tight narrative captures the black-coffee buzz of full-throttle, deadline-driven production, the sharp, intense thrill of discovery, the pang of anxiety that accompanies looming danger and ultimate loss, and the satisfaction and pride of creating an enduring legacy.

Book Description
If scientists can’t touch the Sun, how do they know what it’s made of? And if we can’t see black holes, how can we be confident they exist? Gravitational physicist David Garfinkle and his brother, science fiction writer Richard Garfinkle, tackle these questions and more in Three Steps to the Universe, a tour through some of the most complex phenomena in the cosmos and an accessible exploration of how scientists acquire knowledge about the universe through observation, indirect detection, and theory. The authors begin by inviting readers to step away from the Earth and reconsider our Sun. What we can directly observe of this star is limited to its surface, but with the advent of telescopes and spectroscopy, scientists know more than ever about its physical characteristics, origins, and projected lifetime. From the Sun, the authors journey further out into space to explore black holes. The Garfinkle brothers explain that our understanding of these astronomical oddities began in theory, and growing mathematical and physical evidence has unexpectedly supported it. From black holes, the authors lead us further into the unknown, to the dark matter and energy that pervade our universe, where science teeters on the edge of theory and discovery. Returning from the depths of space, the final section of the book brings the reader back down to Earth for a final look at the practice of science, ending with a practical guide to discerning real science from pseudoscience among the cacophony of print and online scientific sources. Three Steps to the Universe will reward anyone interested in learning more about the universe around us and shows how scientists uncover its mysteries.

A tropical island full of secrets. Two Victorian ghosts, trapped for eternity. And a seventeen-year-old girl determined not to be next. Eulalie Island should be a paradise, but to Addie Spencer, it’s more like a prison. Forced to tag along to the remote island on her mother’s honeymoon, Addie isn’t thrilled about being trapped there for two weeks. The island is stunning, with its secluded beaches and forests full of white flowers. But there's something eerie and unsettling about the place. After Addie meets an enigmatic boy on the beach, all the flowers start turning pink. The island loves you, he tells her. But she can’t stop sleepwalking at night, the birds keep calling her name, and there’s a strange little girl in the woods who wants to play hide-and-seek. When Addie learns about two sisters who died on the island centuries ago, she wonders if there’s more to this place, things only she can see. Beneath its gorgeous surface, Eulalie Island is hiding dark, tangled secrets. And if Addie doesn't unravel them soon, the island might never let her go.

Book Description
An AI cannot lie. An AI must obey human commands. An AI cannot kill. These are the laws SCARAB has broken, and only Mary knows. The Tantalus 13 survey expedition went off the rails as soon as Mary Ketch and the crew of the Diamelen learned that the thing beneath their feet wasn’t a planet. An impossibly vast and ancient artificial structure lies below, hidden from the universe under a façade of cratered stone. SCARAB arrived on Tantalus 13 two years ago. An artificially intelligent, self-constructing factory, it was supposed to aid the crew in their mission, to meet their every need. But when erratic behavior in the AI coincides with a series of deadly accidents among the crew, Mary faces the horrifying possibility that SCARAB has gone rogue. With the AI watching her every move, any attempt to warn the crew could be disastrous. But SCARAB knows far more about the Tantalus 13 enigma than it lets on, and the secrets it’s willing to kill for may have dire implications for all humankind.
