More people have died exploring underwater caves than climbing Mount Everest, and we know more about deep space than we do about the depths of our oceans. From one of the top cave divers working today - and one of the very few women in her field - Into the Planet blends science, adventure, and memoir to bring listeners face-to-face with the terror and beauty of Earth’s remaining unknowns and the extremes of human capability.

Most incidents and accidents are down to "human error". Unfortunately, human error is normal and common, and we can't get rid of it. However, we can reduce the likelihood of one of those - "oh shit moments" - if we have an understanding of human factors and develop our non-technical skills. This is a globally unique book containing decades of research and practice from high-risk domains translated into the world of recreational and technical diving.

David L. Mearns has discovered some of the world's most fascinating and elusive shipwrecks. The Shipwreck Hunter chronicles his most intriguing finds. It describes the extraordinary techniques used, the detailed research, and mid-ocean stamina and courage required to find a wreck thousands of feet beneath the sea, plus the moving human stories that lie behind each of these oceanic tragedies. Combining the adventuring derring-do of Indiana Jones with the precision of a scientist, The Shipwreck Hunter opens an illuminating porthole into the shadowy depths of the ocean.

In 2017, Leonardo da Vinci’s small oil painting the Salvator Mundi was sold at auction. In the words of its discoverer, the image of Christ as savior of the world is “the rarest thing on the planet.” Its $450 million sale price also makes it the world’s most expensive painting. For two centuries, art dealers had searched in vain for the Holy Grail of art history: a portrait of Christ as the Salvator Mundi by Leonardo da Vinci. Many similar paintings of greatly varying quality had been executed by Leonardo’s assistants in the early 16th century.

On a foggy July evening in 1956, the Italian cruise liner Andrea Doria, bound for New York, was struck broadside by another vessel. In eleven hours, she would sink nearly 250 feet to the murky Atlantic Ocean floor. Thanks to a daring rescue operation, only 51 of more than 1,700 people died in the tragedy. But the Andrea Doria is still taking lives. Considered the Mt. Everest of diving, the Andrea Doria is the ultimate deepwater wreck challenge.

Deep is a voyage from the ocean's surface to its darkest trenches, the most mysterious places on Earth. Fascinated by the sport of freediving - in which competitors descend to great depths on a single breath - James Nestor embeds with a gang of oceangoing extreme athletes and renegade researchers. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and other strange phenomena.

At the dawn of the 20th century, when human flight was still considered an impossibility, Germany’s Count Ferdinand von Zeppelin vied with the Wright Brothers to build the world’s first successful flying machine. As the Wrights labored to invent the airplane, Zeppelin fathered the remarkable airship, sparking a bitter rivalry between the two types of aircraft and their innovators that would last for decades, in the quest to control one of humanity’s most inspiring achievements. And it was the airship - not the airplane - that led the way. 

The Ice Diaries tells the incredible true story of Captain William R. Anderson and his crew's harrowing top-secret mission aboard the USS Nautilus, the world's first nuclear-powered submarine. Bristling with newly classified, never-before-published information, The Ice Diaries takes listeners on a dangerous journey beneath the vast, unexplored Arctic ice cap during the height of the Cold War. 

In 1991, acting on a tip from a local fisherman, two scuba divers discovered a sunken German U-boat, complete with its crew of 60 men, not too far off the New Jersey coast. The divers, realizing the momentousness of their discovery, began probing the mystery. Over the next six years, they became expert and well-traveled researchers, taught themselves German, hunted for clues in Germany, and constructed theories corrective of the history books, all in an effort to identify this sunken U-boat and its crew.

His name wasn’t Chester Nez. That was the English name he was assigned in kindergarten. And in boarding school at Fort Defiance, he was punished for speaking his native language, as the teachers sought to rid him of his culture and traditions. But discrimination didn’t stop Chester from answering the call to defend his country after Pearl Harbor, for the Navajo have always been warriors, and his upbringing on a New Mexico reservation gave him the strength to excel as a marine. This is the first and only memoir by one of the original Navajo code talkers of WWII.

Scuba Exceptional may be the fifth in Simon Pridmore’s Scuba series, but it is the true follow up to the first book in the series, Scuba Confidential. It reflects the same philosophy of safe diving through the acquisition of knowledge and skills. The themes are new, there are some wonderful and extremely useful new cautionary tales, and the focus this time is more on issues that face experienced divers. For example, there is more technical diving content, but, as usual, Simon covers complex issues in his usual clear and easy-to-listen-to style.

For at least 20,000 years, we have led not just an earthly existence, but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with the stars shaped who we are - our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost.

We live in a world of seeds. From our morning toast to the cotton in our clothes, they are quite literally the stuff and staff of life, supporting diets, economies, and civilizations around the globe. Just as the search for nutmeg and the humble peppercorn drove the Age of Discovery, so did coffee beans help fuel the Enlightenment and cottonseed help spark the Industrial Revolution. And from the fall of Rome to the Arab Spring, the fate of nations continues to hinge on the seeds of a Middle Eastern grass known as wheat.

In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?
