Astrophysicist and NPR commentator Adam Frank reveals what the latest research on alien civilizations may tell us about our own. Light of the Stars is science at the grandest of scales, and it tells a radically new story about what we are: one world in a universe awash in planets. Building on his widely discussed scientific papers and New York Times op-eds, astrophysicist Adam Frank shows that not only is it likely that alien civilizations have existed many times before, but also that many of them have driven their own worlds into dangerous eras of change. He explains how dust storms on Mars, the greenhouse effect on Venus, Gaia Theory, the threat of nuclear winter, and efforts to prove or disprove the plurality of worlds from Aristotle to Copernicus to Carl Sagan have contributed to our understanding of our place in the universe and the growing challenge of climate change. And he raises what may be the largest question of all: If there has been life on other worlds, what can its presence tell us about our own fate?

Mars, the red planet, is ingrained in our culture, from David Bowie's extra-terrestrial spiders to Captain Scarlet to War of the Worlds. It has inspired hundreds of authors, scientists and science-fiction writers - but why? What is it about this particular planet that makes it so intriguing? Ancient mythologies defined Mars as a violent harbinger of war, star-gazers puzzled over its peculiar motion, and astrologers defined human personalities by its position and bizarre dance through the sky. And in more recent times, astronomers have explored Mars and its alien characteristics: its dusty red hue, its small moons, its atmosphere, how the planet formed and its mysterious past. Images sent back from various satellites showed startling faces, canals, and pyramids across its surface. Were there Martians, and were they civilised, intelligent, beings? Science-fact is now catching up with science fiction. Robot vehicles have trundled across the planet's surface, beaming back beautiful views of its rust-orange surface, and testing soil and atmosphere to get clues on how the planet has evolved, and whether it supported (or supports) life. There are many more Mars missions planned over the next decade. And while little green Martians are now firmly the preserve of literature, there is growing evidence that the now arid, frozen planet was once warm, wet, and possibly thronging with microbial life. And one day soon humans will set foot on the red planet. What are the challenges involved, and how are we preparing for them? Is there a long-term future for humans on Mars? Nicky Jenner's 4th Rock from the Sun reviews Mars in its entirety - its nature, attributes, and impact on 3rd Rock-culture, its environmental science and geology, and its potential as a human colony - everything you need to know about the Red Planet (and quite a few things you don't).

In the near future, enormous silver spaceships appear without warning over mankind’s largest cities. They belong to the Overlords, an alien race far superior to humanity in technological development—and their purpose is to dominate the Earth. Their demands, however, are surprisingly beneficial—end war, poverty, and cruelty. Their presence, rather than signaling the end of humanity, ushers in a golden age—or so it seems. But it comes at a price. Without conflict, humanity ceases to work toward creative achievement, and culture stagnates. And as the years pass, it becomes more and more clear that the Overlords have a hidden agenda for the evolution of the human race—that may not be as beneficial as it seems. Originally published in 1953, Childhood’s End is Clarke’s first successful novel—and is considered a classic of science fiction literature. Its dominating theme of transcendent evolution appears in many of Clarke’s later works, including the Space Odyssey series. In 2004, the book was nominated for the Retro Hugo Award for Best Novel.

Deep Life takes readers to uncharted regions deep beneath Earth's crust in search of life in extreme environments and reveals how astonishing new discoveries by geomicrobiologists are helping the quest to find life in the solar system. Tullis Onstott, named one of the 100 most influential people in America by Time magazine, provides an insider’s look at the pioneering fieldwork that is shining vital new light on Earth’s hidden biology—a thriving subterranean biosphere that scientists once thought to be impossible. Come along on epic descents two miles underground into South African gold mines to experience the challenges that Onstott and his team had to overcome. Join them in their search for microbes in the ancient seabed below the desert floor in the American Southwest, and travel deep beneath the frozen wastelands of the Arctic tundra to discover life as it could exist on Mars. Blending cutting-edge science with thrilling scientific adventure, Deep Life features rare and unusual encounters with exotic life forms, including a bacterium living off radiation and a hermaphroditic troglodytic worm that has changed our understanding of how complex subsurface life can really be. This unforgettable book takes you to the absolute limits of life—the biotic fringe—where today’s scientists hope to discover the very origins of life itself.
