Earth Space Science

When on land, rivers, lakes, and oceans appear flat. With the aid of satellites, these bodies of water appear to have many designs! Explore the art of nature and how satellites detect the temperature of the many bodies of water around the globe.

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.

What if the stars were no longer far away? In this sweeping exploration of a future without distance, this book asks what would happen if humanity could step from world to world as easily as crossing a room. From the first leap beyond Earth to the governance of civilizations scattered across the galaxy, it traces the promises, perils, and moral dilemmas of a universe suddenly within reach.

Earth's Diaspora is well underway and the colonies are flourishing. There are Dynasties of The Accord, however, that resent Earth's expansion. Charli Morgan and Lucca Spelini each lead their respective teams from colony to colony, preventing interference and keeping the peace. Standing up to the Dynasties is one thing, but what happens when Lower Houses of The Accord start butting in?

The marauders, terrors from deep space, hit us hard. Our starships shattered. Our armies collapsed. Our cities crumbled. As Earth smolders, the marauders imprison us in camps. They farm us like cattle. They torture us for sport. Earth weeps. But there is hope. The Ghost Fleet, an ancient alien armada, might still exist in deep space. In a single starship, Sergeant Marco Emery and his friends seek this mythical fleet. They must find it. They must return with its might. Or the marauders will kill us all.

Five years ago, we won our first galactic war. We defeated the scum, a race of alien centipedes. But the marauders are stronger, smarter, and crueler by far. And they will show us no mercy. Marco Emery, hero of the last war, struggles today as a civilian. Shell shock cripples him. Nightmares haunt him. Yet now he must become a soldier again. Now his old platoon must reunite. Together, they must defeat the greatest threat Earth has ever known. Or humanity will fall.

Rosa De Angelo and Ellen McCarthy are about to become two of the newest victims of SEAS - Severe Environmental Allergy Syndrome. Haunted by dreams of orbs in the night, they wake up to news reports of UFO swarms and alien abductions by the thousands. Separated from their families, Rosa and Ellen are ushered into isolation tent cities established to prevent the public from having any further exposure to the growing number of SEAS victims.

Ten years ago the Sythians invaded the galaxy with one goal: to wipe out the human race. Now the survivors are hiding in the last human sector of the galaxy: Dark Space--once a place of exile for criminals, now the last refuge of mankind.

The time of the Great Exodus is over. Centuries have passed. Earth is overpopulated, and the fate of the colonists who traveled to the stars is unknown. An attempt to start the second wave of expansion has led to a shocking discovery: All accessible planets located within one hyperjump from the Solar System have been settled during the Great Exodus. The colonists have created unique and distinctive civilizations - but none of that matters when the survival of billions of Terrans is at stake.

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.

They say that necessity is the mother of all inventions. Amir Weatherby has the world in his hands, quite literally. When his company discovers an asteroid on a direct collision course with Earth, they decide to keep the news quiet and find a way to survive the impending apocalypse themselves. Secret projects begin with the intent of preventing the world going the same way as the dinosaurs.

Earth in 2064 is politically corrupt and in economic decline. The Long Depression has dragged on for 56 years, and the Bureau of Sustainable Research is hard at work making sure no new technologies disrupt the planned economy. Ten years ago, a band of malcontents, dreamers, and libertarian radicals bolted privately developed antigravity drives onto rusty seagoing cargo ships, loaded them to the gills with 20th-century tunnel-boring machines and earthmoving equipment, and set sail—for the moon.

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.

The unabridged and enhanced 2nd edition of Zetetic Astronomy, formulated in the 19th century by Samuel Rowbotham, presents a flat-earth cosmology grounded in direct sensory observation rather than theoretical abstraction. Rejecting Newtonian and Copernican astronomy, Rowbotham argued that the Earth is a flat, stationary plane with the Sun, Moon, and stars moving in circular paths above it, asserting that empirical evidence—such as the apparent flatness of horizons and the behavior of water surfaces—supports this model.

United we stand. Divided we fall. We stood together once. United. Proud. Humanity was one. Together we colonized the stars. Together we built an empire. That was a long time ago. Today humanity is fractured. Earth and Mars clash in war. Brother fights brother. Our fleets once faced the stars. Today they face each other in battle. Our empire frays. Hearts that once blazed with courage now burn with hatred. Meanwhile the true enemy draws ever nearer.

For anyone who has ever looked up at the stars and wondered what it all means, Isaac Asimov's Guide to Earth and Space is indispensable. In this audio, Asimov's gift for popular and entertaining exposition has never been better deployed, with his succinct answers to the most intriguing questions about planets, stars, and galaxies. What are quasars? How was the Earth formed? Puzzled by pulsars?

They say hard times create strong men, strong men create good times, good times create weak men, and weak men create hard times. Marco Emery was born into hard times. He was raised in war. He grew up in bomb shelters and on battlefields, fighting to survive. He became a soldier. A war hero. Then, after vanquishing his last enemy, he retired to raise a family. And Earth moved on.

Today, we take for granted that a telescope allows us to see galaxies millions of light years away. But before its invention, people used nothing more than their naked eye to fathom what took place in the visible sky. So how did four men in the 1500s - of different nationality, age, religion, and class - collaborate to discover that the Earth revolved around the Sun? With this radical discovery that went against the Church, they created our contemporary world. Heaven on Earth is an intimate examination of this scientific family.
