Earth Space Science

No one on Earth knows the seeds of the world’s destruction just fell from space. Tiana knows what duty means though. It's why all her friends are dead. Alone on a primitive world. All her all her technology at the bottom of the ocean. Outnumbered by deadly enemies only she can bring to justice. If she fails her mission now, another sentient species will fall. And the Tyrant Empire will rise again - because Earth has just been infected with a fatal parasite.

Quando Wic finalmente vede ciò che la squadra di ricercatori ha scoperto, non può credere ai propri occhi: una tempesta furibonda si sta per scatenare sulla Terra.

The fifth installment of an epic science-fiction series that tells of humanity's desperate struggle to survive against an overwhelming alien invasion.

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.

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.

Every minute, several huge “snowballs” break up as they approach the Earth and deposit a large cloud of water vapor in Earth’s upper atmosphere. That’s the startling finding that world-renowned physicist Louis A. Frank came to after studying the images from the Dynamics Explorer 1 spacecraft. His conclusion, based on data acquired at the limits of detection, created a storm of controversy among scientists. This is the story that was told in The Big Splash, published in 1990. But, the story does not end there.

Earth stands on the brink of doom, but hope lies in the Bertram Ramsay Space Station, evacuating seven million survivors. Jaxon Leith is struggling to recover from the explosion that rocked Compression, halting the evacuation and leaving two million legitimate occupants stranded on Earth. Together with the rest of the covert operations team, Jaxon continues the mission to neutralise the station's biggest threat: The Acolytes of Gaia.

Ancient people from many different cultures - Greek, Roman, Mezo-American, Arab - all looked up and imagined pictures in the sky by "drawing" a line from one star to another, like a connect-the-dots puzzle. These star pictures - constellations - represented myths and legends from the various cultures that still fascinate us today.

The Earth had four fleets to fight the invading enemy. The first fleet valiantly protected earth, but it wasn’t enough. Three fleets would arrive soon and end the threat...but they never came through the wormhole. One ship escaped the massacre, fleeing deep into space while the rest of Earth’s defenses were destroyed. Only the barrier around the planet keeps the enemy from finishing what they started.

Un secreto enterrado en la Antártida por miles de años. Y un sargento muy cabreado por tener que hacer de niñera para los investigadores que tienen que resolver el misterio.

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.
