Earth Space Science

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?

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.

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 Confederation has decided that Earth represents a significant danger to their future plans of Empire. A massive fleet is dispatched to destroy the Solar System and every Human on its planets, moons, and asteroids. If the Solar System falls, the fledging Human Empire will have no chance of survival. Admiral Reynolds is tasked with defending the Solar System and preserving as many Human lives as possible. He knows he faces a nearly impossible task as he does not have the ships needed to stop the coming attack.

Earth is rising in the House of Voltar.... And there’ll be hell to pay! That’s right. The invasion is on...and it’s coming soon to a galaxy near you. The action couldn’t be hotter, and the plot couldn’t be more diabolical. Earth is coming to Voltar - and the Voltarians won’t know what hit them. Murder, blackmail, drugs, psychoanalysis, PR firms, sex-crazed teenyboppers, riots in the streets, women in chains. These are the powerful secret weapons of war.

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.

As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realization that the dinosaurs were wiped out by just such an impact. Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects and plans for high-tech hardware that could deflect an incoming object from a collision course.

Mind Openers 2.0 is the second installment in a two-part set. It takes a fresh look at relativity, cosmology, and quantum theory by imagining a “sandbox universe”, in which space and time are treated as tangible and visualizable phenomena. In addition to providing an intuitive feel for the physics, the model makes a number of acutely unexpected predictions. The author is a geophysicist (MSc, fellow of geoscientists, Canada) and educator, who specializes in translating scientific material for the non-expert.

The Trellixian Empire was constantly expanding, seeking new worlds for its ever-increasing population. If worlds were discovered with existing sentient populations, they were cleansed to make room for colonization. Hundreds of budding civilizations had been eliminated by Trellixian battle fleets. On Earth, years in the past, a scout ship fleeing from the Trellixians crashed. Scientists investigating the wreckage discovered what the Trellixians had done to the world the scout ship escaped from. They also discovered it was only a matter of time before the Trellixians reached Earth.

This is Issue 98 of Cosmos, a quarterly science magazine. Produced by The Royal Institution of Australia, Cosmos aims to inspire curiosity in "The Science of Everything" and make the world of science accessible to everyone.

Mars, the red planet, is ingrained in our culture, from David Bowie's extra-terrestrial spiders to Captain Scarlet to War of the Worlds. It has inspired hundreds of authors, scientists and science-fiction writers - but why? What is it about this particular planet that makes it so intriguing? Ancient mythologies defined Mars as a violent harbinger of war, star-gazers puzzled over its peculiar motion, and astrologers defined human personalities by its position and bizarre dance through the sky.

Meet our fearless adventurers Cassandra, Otto and Missy AKA the smartest raven in the universe as they set out on their next action-packed Ladybird Audio Adventure! On this adventure, we're travelling to the arid desert where we'll learn about the different species that live in these hot climes, such as coyotes, lions and rattlesnakes! Remember to bring plenty of water on this journey as we'll be exploring the driest deserts on earth!

We've pinpointed the destination, refined the technology, designed the habitat. Are we forgetting something? A timely reminder that it's not just rocket science, this book explores the all-too-human issues raised by the prospect of settling in outer space. Accordingly, her work highlights the complex ethical challenges that accompany any other-worldly venture—questions about the environment, labor rights, and medical ethics, among others.

Captain Clayton Cross and his crew encountered the Kyra, an advanced race of avian carnivores. They fled this first encounter, but the Kyra beat them back to Earth by almost a century. Earth lost the war in just a few weeks. Our cities burned, and billions died. After we surrendered, the Kyra helped us to rebuild, but on their terms, confining us to city centers and building high walls to keep us in.

After three years of exile from humanity's war against the Kurians, David Valentine returns to battle. The Lifeweavers, Earth's allies in the conflict, have mostly vanished, but those that remain are held captive by an overlord known as the Seattle Kurian. To free them, Valentine must convince the legendary resistance fighter known as Adler to join his cause. But the "Old Man" is something of an overlord himself....

The basilisks. Giant serpents from deep space. Their true name is unknown. Their homeworld is cloaked in shadow. But one thing is certain: They're killers. And they vow to kill us all.

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.

Fleet Commander Kamuss of the Voltrex Federation is fighting a desperate battle to keep the massive Trellixian Empire at bay. His fleet pushes deep into the Empire facing impossible odds with stiffer resistance in every fleet engagement. Battle Commander Balforr of the Trellixian Empire has one objective driving him.

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.
