In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature.

We now know that the universe is mostly dark, made up of particles and forces undetectable by our most powerful telescopes. The discovery signaled a Copernican-like revolution in astronomy: not only are we not the center of the universe, neither is the stuff of which we're made. Vera Rubin played a pivotal role in this discovery. By showing that some astronomical objects seem to defy gravity, Rubin helped convince the scientific community of the possibility of dark matter. In Bright Galaxies, Dark Matter, and Beyond, Ashley Jean Yeager tells the story of Rubin's life and work.

Historian William Sheehan and astronomer and planetary scientist Jim Bell combine their talents to tell a unique story of what we've learned by studying Mars through evolving technologies. What the eye sees as a mysterious red dot wandering through the sky becomes a blurry mirage of apparent seas, continents, and canals as viewed through Earth-based telescopes.

Brad Steiger, the world-renowned authority on unexplained phenomena, presents a collection of UFO encounters and abductions. His provocative theories provide answers to the most puzzling questions: Why are they here? What do they want? And how will they change the fate of the human race?

Geneticist Adam Rutherford and mathematician Hannah Fry guide listeners through time and space, through our bodies and brains, showing how emotions shape our view of reality, how our minds tell us lies, and why a mostly bald and curious ape decided to begin poking at the fabric of the universe.

The United States Space Force has a noble mission - to protect America, to support our allies, and to support our nation's interest as we, along with other nations, move out into the little patch of the universe that is our home system. The desire to establish a US Space Force has been around for decades, in both science fiction and in the minds of people who attempt to seriously consider what our nation needs in order to deter future wars (and if necessary, to fight and win them).

Space exploration is as much a story of leadership and teamwork as it is a story of exploration and discovery. Leadership Moments from NASA delves into the organizational culture, leadership styles, and insights of NASA senior executives spanning five decades of human spaceflight, to share the lessons they learned from critical moments where they took on seemingly insurmountable challenges.

On a moonless night in January 1991, a dozen US aircraft appeared in the skies over Baghdad. To the Iraqi air defenses, the planes seemed to come from nowhere. Each aircraft was more than 60 feet in length and with a wingspan of 40 feet, yet its radar footprint was the size of a ball bearing. Here was the first extensive combat application of Stealth technology. And it was devastating.

Human travel into space is an enormously expensive and unforgiving endeavor. So why go? In this accessible and authoritative book, astrophysicist Martin Elvis argues that the answer is the asteroid exploration, for the strong motives of love, fear, and greed. Elvis explains how each motive can be satisfied, and how they help one another. From the origins of life, to "space billiards," and space sports, Elvis looks at how asteroids may be used in the not-so-distant future.

The first operational military jet in the world, toward the end of the Second World War, the Me 262 was to be the German "miracle weapon". Mano Ziegler was involved from its inception and contributed to the design, testing, training, and even served in it operationally. Could the Me 262 have broken the Allied supremacy in the air? Hitler's Jet Plane fills an important gap in the history of the Luftwaffe and of aviation in general with new research which discloses how the first military jet plane failed to make its mark on World War II.

The fate of the Lost Ark of the Covenant is one of the great historical mysteries of all time. The Bible contains hundreds of references to the Ark's power, but the Ark itself mysteriously disappears from recorded history sometime after the building of the Temple of Solomon. After 10 years of searching through the dusty archives of Europe and the Middle East, Graham Hancock has succeeded where scores of others have failed. This intrepid journalist has tracked down the true story behind the myths and legends - revealing where the Ark is today, how it got there, and why it remains hidden.

In this one-of-a-kind memoir, Jack Clemons - a former lead engineer in support of NASA - takes listeners behind the scenes and into the inner workings of the Apollo and Space Shuttle programs during their most exciting years. Discover the people, the events, and the risks involved in one of the most important parts of space missions: bringing the astronauts back home to Earth. Clemons joined Project Apollo in 1968, a young engineer inspired by science fiction and electrified by John F. Kennedy's challenge to the nation to put a man on the moon.

This audiobook explores how the discoveries within the Solar System and of exoplanets far beyond it come together to help us understand the habitability of Earth, and how these findings guide the search for exoplanets that could support life. The author highlights how, within two decades of the discovery of the first planets outside the Solar System in the 1990s, scientists concluded that planets are so common that most stars are orbited by them. The lives of exoplanets and their stars are inextricably interwoven.

On a cold January morning in 1986, NASA launched the Space Shuttle Challenger, despite warnings against doing so by many individuals including Allan McDonald. The fiery destruction of Challenger on live television moments after launch remains an indelible image in the nation's collective memory. In Truth, Lies, and O-Rings, McDonald, a skilled engineer and executive, relives the tragedy from where he stood at Launch Control Center.

The summer of 1969 saw astronauts land on the moon for the first time and hippie hordes descend on Woodstock for a legendary music festival. For Neil M. Maher, the conjunction of these two era-defining events is not entirely coincidental. With its lavishly funded mandate to send a man to the moon, Apollo became a litmus test in the 1960s culture wars.

On July 23, 1999, the Chandra X-Ray Observatory, the most powerful X-ray telescope ever built, was launched aboard the space shuttle Columbia. Since then, Chandra has given us a view of the universe that is largely hidden from telescopes sensitive only to visible light. In Chandra's Cosmos, Wallace H. Tucker uses a series of short, connected stories to describe the telescope's exploration of the hot, high-energy face of the universe.

Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy. Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks listeners to imagine - and choose among-five scenarios for finding life.

How many Carl Sagan fans know that while the renowned scientist was at Stanford University, he produced a controversial paper, funded by a NASA research grant, that concludes that ancient alien intervention may have sparked human civilization? Author Donald L. Zygutis lays out a compelling case that points to a cover-up by the Pentagon and NASA, who may have buried it soon after it was written. How significant is the Stanford paper?

Eclipses have stunned, frightened, emboldened, and mesmerized people for thousands of years. They were recorded on ancient turtle shells discovered in the Wastes of Yin in China, on clay tablets from Mesopotamia and on the Mayan "Dresden Codex". They are mentioned in Homer's Iliad and Odyssey and at least eight times in the Bible. Columbus used them to trick people, while Renaissance painter Taddeo Gaddi was blinded by one. Sorcery was banished within the Catholic Church after astrologers used an eclipse to predict a pope's death.

Award-winning science writer and documentarian Rod Pyle presents an insider's perspective on the most unusual and bizarre space missions ever devised inside and outside of NASA. The incredible projects described here were not merely flights of fancy....
