April 25, 1986 in Chernobyl was a turning point in world history. The disaster not only changed the world’s perception of nuclear power and the science that spawned it, but also our understanding of the planet’s delicate ecology. With the images of the abandoned homes and playgrounds beyond the barbed wire of the 30-kilometer Exclusion Zone, the rusting graveyards of contaminated trucks and helicopters, the farmland lashed with black rain, the event fixed for all time the notion of radiation as an invisible killer.

The Mongol army led by Genghis Khan subjugated more lands and people in 25 years than the Romans did in 400. In nearly every country the Mongols conquered, they brought an unprecedented rise in cultural communication, expanded trade, and a blossoming of civilization.

Nina Sankovitch’s American Rebels explores, for the first time, the intertwined lives of the Hancock, Quincy, and Adams families, and the role each person played in sparking the American Revolution. American Rebels explores how the desire for independence cut across class lines, binding people together as well as dividing them -rebels versus loyalists - as they pursued commonly held goals of opportunity, liberty, and stability. Nina Sankovitch's new audiobook is a fresh history of our revolution that makes listeners look more closely at Massachusetts.

In this astonishing rediscovery of the final Apollo moon landings, the acclaimed author of Chesapeake Requiem reveals that these extraordinary yet overshadowed missions - distinguished by the use of the revolutionary lunar roving vehicle - deserve to be celebrated as the pinnacle of human adventure and exploration.

Werner Herzog was born in September 1942 in Munich, Germany, at a turning point in the Second World War. Soon Germany would be defeated and a new world would have to be made out the rubble and horrors of the war. Fleeing the Allied bombing raids, Herzog’s mother took him and his older brother to a remote, rustic part of Bavaria where he would spend much of his childhood hungry, without running water, in deep poverty. It was there, as the new postwar order was emerging, that one of the most visionary filmmakers of the next seven decades was formed.

When NASA sent astronauts to the moon in the 1960s and 1970s the agency excluded women from the corps, arguing that only military test pilots—made up exclusively of men—had the right stuff. It was an era in which women were steered away from jobs in science and deemed unqualified for space flight. Eventually, though, NASA recognized its blunder and opened the application process to a wider array of hopefuls, regardless of race or gender. From a candidate pool of 8,000 six elite women were selected in 1978—Sally Ride, Judy Resnik, Anna Fisher, Kathy Sullivan, Shannon Lucid, and Rhea Seddon.

The Anthropocene is the current geologic age, in which humans have profoundly reshaped the planet and its biodiversity. In this remarkable symphony of essays adapted and expanded from his groundbreaking podcast, best-selling author John Green reviews different facets of the human-centered planet on a five-star scale - from the QWERTY keyboard and sunsets to Canada geese and Penguins of Madagascar.

By August 1968, the American space program was in danger of failing in its two most important objectives: to land a man on the moon by President Kennedy's end-of-decade deadline and to triumph over the Soviets in space. With its back against the wall, NASA made an almost unimaginable leap: It would scrap its usual methodical approach and risk everything on a sudden launch, sending the first men in history to the moon - in just four months.

The Overlords appeared suddenly over every city - intellectually, technologically, and militarily superior to humankind. Benevolent, they made few demands: unify earth, eliminate poverty, and end war. With little rebellion, humankind agreed, and a golden age began.

The future is here...in an adventure of cosmic dimension. In December, 1999, a multinational team journeys out to the stars, to the most awesome encounter in human history. Who - or what - is out there? In Cosmos, Carl Sagan explained the universe. In Contact, he predicts its future - and our own.

A revolution is underway. For the first time in human history, we are at the cusp of experiencing contact with nonhuman life-forms of all kinds due to technological innovations and research into the experiences of people at the forefront of this development. In Encounters, author D.W. Pasulka takes listeners to the forefront of this revolution, sharing the work of experts across a spectrum of fields who are working to connect humanity with unknown life-forms.

Mars was once similar to Earth, but today there are no rivers, no lakes, no oceans. Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science. In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.

In fascinating and personal detail, and based on exclusive diaries and audio recordings from his mission, Tim Peake takes listeners closer than ever before to experience what life in space is really like: the sacrifice that astronauts make in being apart from their families, the sights, the smells, the fear, the exhilaration and the deep and abiding wonder of the view from space. Limitless is a book about the power of following our dreams - however unlikely they may seem - and of striving to reach our potential, even when we might not believe in it ourselves.

The Los Angeles Times headline screamed: Rocket Scientist Killed in Pasadena Explosion. The man known as Jack Parsons, a maverick rocketeer who helped transform a derided sci-fi plotline into actuality, was at first mourned as a scientific prodigy. But reporters soon uncovered a more shocking story: Parsons had been a devotee of the city’s occult scene.

In the 1940s and '50s, when the newly minted Jet Propulsion Laboratory needed quick-thinking mathematicians to calculate velocities and plot trajectories, they didn't turn to male graduates. Rather, they recruited an elite group of young women who, with only pencil, paper, and mathematical prowess, transformed rocket design, helped bring about the first American satellites, and made the exploration of the solar system possible.
