The Sun gives life to our planet, but it also produces some amazing phenomena. From sun dogs and green flash to solar flares and sunspots, The Science Behind Wonders of the Sun looks at some of these phenomena, explaining how and why they occur.

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.

Tesla is the envy of the automotive world. Born at the start of the millennium, it was the first car company to be valued at $1 trillion. Its CEO, the mercurial, charismatic Elon Musk has become not just a celebrity but the richest man in the world. But Tesla’s success was far from guaranteed. Founded in the 2000s, the company was built on an audacious vision. Musk and a small band of Silicon Valley engineers set out to make a car that was quicker, sexier, smoother, and cleaner than any gas-guzzler on the road.

Award-winning author and mathematician Joseph Mazur provides an engaging exploration of how the understanding of time has evolved throughout human history and offers a compelling new vision, submitting that time lives within us. Our cells, he notes, have a temporal awareness, guided by environmental cues in sync with patterns of social interaction. Listeners learn that, as a consequence of time's personal nature, a 48-hour journey on the Space Shuttle can feel shorter than a six-hour trip on the Soyuz capsule and that the Amondawa of the Amazon do not have ages.

In the depths of the Arctic, where the ice never melts and silence reigns supreme, lies Station Nine—a place forgotten by time, yet haunted by secrets too vast to contain. It was here that humanity’s reach exceeded its grasp, where ambition and curiosity collided with forces older than the stars themselves. This is the story of Subject Zero—once a man named Eli, now a vessel for an alien intelligence that defies comprehension. It is a tale of creation and destruction, of the thin line between life and something far stranger, and of the price paid when we attempt to play god with the ...

At noon on October 27, 1924, a factory worker was admitted to a hospital in New York City, suffering from hallucinations and convulsions. Before breakfast the next day, he was dead. Alice Hamilton was determined to prevent such a tragedy from happening again. By the time of the accident, Hamilton had pioneered the field of industrial medicine in the United States. She specialized in workplace safety years before the Occupational Safety and Health Administration was created. But this time, she was up against a formidable new foe: America’s relentless push for progress, regardless of the cost.

As a kid, Aomawa Shields was always bumping into things, her neck craned up at the sky, dreaming of becoming an astronaut. A year into an astrophysics PhD program, plagued by self-doubt and discouraged by a white male professor who suggested that she—a young Black woman who also loved fashion, makeup, and the arts—didn’t belong, she left astronomy and pursued acting professionally for a decade, before a day job working for NASA’s Spitzer Space Telescope drew her back to the stars.

After a few billion years of bearing witness to life on Earth, of watching one hundred billion humans go about their day-to-day lives, of feeling unbelievably lonely, and of hearing its own story told by others, The Milky Way would like a chance to speak for itself. All one hundred billion stars and fifty undecillion tons of gas of it. It all began some thirteen billion years ago, when clouds of gas scattered through the universe's primordial plasma just could not keep their metaphorical hands off each other.

When a bolt of lightning ignited a hilltop in the sleepy town of Yarnell, Arizona, in June of 2013, setting off a blaze that would grow into one of the deadliest fires in American history, the 20 men who made up the Granite Mountain Hotshots sprang into action. An elite crew trained to combat the most challenging wildfires, the Granite Mountain Hotshots were a ragtag family crisscrossing the American West and wherever else the fires took them. The Hotshots were loyal to one another and dedicated to the tough job they had.

In The Glass Cage, bestselling author Nicholas Carr digs behind the headlines about factory robots and self-driving cars, wearable computers and digitized medicine, as he explores the hidden costs of granting software dominion over our work and our leisure. Even as they bring ease to our lives, these programs are stealing something essential from us.

David K. Stumpf demystifies the intercontinental ballistic missile program that was conceived at the end of the Eisenhower administration as a key component of the US nuclear strategy of massive retaliation. Although its nuclear warhead may have lacked power relative to that of the Titan II, the Minuteman more than made up for this in terms of numbers and readiness to launch - making it the ultimate ICBM.

In Secrets of Antigravity Propulsion, physicist Paul LaViolette reveals the secret history of antigravity experimentation—from Nikola Tesla and T. Townsend Brown to the B-2 Advanced Technology Bomber. He discloses the existence of advanced gravity-control technologies, under secret military development for decades, that could revolutionize air travel and energy production.

Werner Heisenberg's "uncertainty principle" challenged centuries of scientific understanding, placed him in direct opposition to Albert Einstein, and put Niels Bohr in the middle of one of the most heated debates in scientific history. Heisenberg's theorem stated that there were physical limits to what we could know about sub-atomic particles; this "uncertainty" would have shocking implications.

G. Wayne Miller has dramatically and meticulously reconstructed an amazing true story: how a group of renegade Minnesota surgeons, led by Dr. Walt Lillehei, made medical history by becoming the first doctors to operate deep inside the human heart.

Galileo Galilei was the foremost scientist of his day. Though he never left Italy, his inventions and discoveries were heralded around the world. His telescopes allowed him to reveal the heavens and enforce the astounding argument that the earth moves around the sun. For this belief, he was brought before the Holy Office of the Inquisition, accused of heresy, and forced to spend his last years under house arrest.

The story of the bullet-shaped SpaceShipOne and the other teams in the hunt is an extraordinary tale of making the impossible possible.
