Earths Astronomy

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.

Beliefs about the shape of the earth have varied over the millennia, but the Ancient Greeks were able to observe that our planet is round and even Eratosthenes attempted to measure its size. It was not until explorers had fully charted the globe that most people were really able to comprehend its spherical shape.

Former NASA astronaut Terry Virts offers an insider's guide to astronauting—a behind-the-scenes look at the training, the basic rules, lessons, and procedures of space travel, including how to deal with a dead body in space, what it’s like to film an IMAX movie in orbit, what exactly to do when nature calls, and much more, in 51 brief chapters.

The sun's family of planets become a familiar place in this personal account of the lives of other worlds. Sobel explores the planets' origins and oddities through the lens of popular culture, from astrology, mythology, and science fiction to art, music, poetry, biography, and history. This intimate account is filled with fascination, beauty, and surprise.

Some see dust as dull stuff, useless at best, and sneeze-inducing at worst. But in the hands of writer Hannah Holmes, dust becomes a dazzling and mysterious force. As Holmes says, dust is a messenger, and air is its medium. And by the end of this fascinating journey through The Secret Life of Dust, we cannot help but agree.

In researching one of history's greatest scientific quests, a mission to measure the Earth and define the meter, Ken Alder stumbled on a 200-year-old secret: The meter, it turns out, is in error. This is a story of two men, a secret, and a timeless human dilemma: is it permissible to perpetuate a small lie in the service of a larger truth?

What causes Jupiter’s Great Red Spot? How have volcanoes shaped the land on many planets? How do space shuttles launch and dock with space stations? This series introduces young listeners to the objects within our solar system and the tools people use to explore the mysteries of space. This volume includes Earth, Jupiter, Mars, Mercury, Neptune, and Saturn.

The astronauts headed to the moon in December 1972 thought they knew what to expect. They would soon be exploring the moon’s surface in a lunar rover, traveling farther than anyone before them. They would be collecting soil and rock samples for study back on Earth and could expect to learn about the moon’s physical makeup and age.

Zetetic Astronomy is the magnum opus of Samuel Rowbotham (1816-1884), a self-taught polymath, debater, faith healer, and early advocate of Utopian socialism. Drawing from a wide variety of contemporary sources, Christian scripture, and his own investigative and experimental skills, Rowbotham advocated tirelessly for his thesis that the true shape of the Earth was a plane, refuting all suggestions of rotundity. His arguments continue to captivate, persuade, and entertain up to the present day.

In this deeply original book, science writer Anil Ananthaswamy sets out in search of the telescopes and detectors that promise to answer the biggest questions in modern cosmology. Why is the universe expanding at an ever faster rate? What is the nature of the "dark matter" that makes up almost a quarter of the universe? Why does the universe appear fine-tuned for life? Are there others besides our own?

In 1977, two extraordinary spacecraft called Voyager were launched to the stars. Affixed to each Voyager craft was a gold-coated copped phonograph record as a message to possible extra-terrestrial civilizations that might encounter the spacecraft in some distant space and time.

Meet Moon! She's more than just a rock - she’s Earth’s rock, her best friend she can always count on. Moon never turns her back on her friend (Literally: She's always facing Earth with the same side!). These two will stick together forever. With characteristic humor and charm, Stacy McAnulty channels the voice of Moon in this next celestial "autobiography" in the Our Universe series.

Satellites may exist out in space, but they let us study Earth from the outside looking in. From climate change to natural disasters and more, find out how scientists are using satellites to tackle some of our world's most challenging problems.

Earth, from space, looks like a shimmering gem suspended in an inky, infinite expanse. But this serene image masks the magnificent and volatile interior forces that make life possible for millions of species on the surface. The placid appearances of our neighboring planets similarly belie their powers—and science fiction-worthy features, like diamond rain.

"Hi, I’m Earth! But you can call me Planet Awesome." Prepare to learn all about Earth from the point of view of Earth herself! In this funny yet informative book, filled to the brim with kid-friendly facts, listeners will discover key moments in Earth’s life, from her childhood more than four billion years ago all the way up to present day. Beloved children's book author Stacy McAnulty helps Earth tell her story.

Nuestra existencia está amenazada: las glaciaciones, los impactos de asteroides, la capacidad finita de la Tierra e incluso la lejana pero inevitable muerte del Sol son riesgos de tal magnitud que, si no abandonamos la Tierra, deberemos asumir la idea de nuestra extinción. Por eso, para Michio Kaku nuestro destino yace en las estrellas, no por la curiosidad o la pasión aventurera que los humanos llevamos dentro, sino por una simple cuestión de supervivencia.

With wonder, wit, and flair - and in record time and space - geophysicist David Bercovici explains how everything came to be everywhere, from the creation of stars and galaxies to the formation of Earth's atmosphere and oceans to the origin of life and human civilization. Bercovici marries humor and legitimate scientific intrigue, rocketing listeners across nearly 14 billion years and making connections between the essential theories that give us our current understanding of topics as varied as particle physics, plate tectonics, and photosynthesis.

Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the solar system passed through a disk of dark matter embedded in the Milky Way. In a sense it might have been dark matter that killed the dinosaurs.

If a black hole is not a hole, then what is it? Find out what black holes are, what causes them, and how scientists first discovered them. Learn how astronomers find black holes, get to know our nearest black-hole neighbor, and take a journey that will literally s-t-r-e-t-c-h the mind.

An extraterrestrial colony, in some form, may already exist, just awaiting discovery. But the greatest impediment to such an important scientific discovery may not be technological, but political. No scientific endeavor can be launched without a budget, and matters of money are within the arena of politicians. Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities.
