Current Earth Event Science

Space weather is all around us. And although there are no nightly news reports on the latest front moving through the heavens, we're rapidly developing the tools necessary to measure and observe trends in cosmic meteorology. But why does space weather matter to us? It doesn't affect whether we bring an umbrella to work or require us to monitor early school closings. It's far, far away and of little concern to us...right? March 13, 1989. The Department of Defense tracking system that keeps tabs on 8,000 objects orbiting Earth briefly loses track of 1,300 of them. In New Jersey a surge of extra current in the power lines fries a $10 million transformer. Shocks to a power station in Quebec leave 6 million people without electricity for nine hours. Residents of Florida, Mexico, and the Grand Cayman Islands see glowing curtains of light in the sky. All these bizarre and seemingly random events were caused by a series of solar explosions that launched bolts of electrified gas at the Earth. Trillions of watts of electricity had poured into the atmosphere--double the power-generating capacity of the entire United States. "Storms from the Sun explores the emerging science of space weather and traces its increasing impact on a society that has become dependent on space-based technologies. Authors Carlowicz and Lopez explain what space weather really means to us down here--and what it may mean for future explorations and colonization of distant worlds. By translating the latest findings of NASA and other top scientists into fascinating and accessible descriptions of the latest discoveries, we are privy to some of the most closely held secrets that the solar-terrestrial system has to offer.

In this new edition of Questioning the Millennium, best-selling author Stephen Jay Gould applies his wit and erudition to one of today's most pressing subjects: the significance of the millennium. In 1950 at age eight, prompted by an issue of Life magazine marking the century's midpoint, Stephen Jay Gould started thinking about the approaching turn of the millennium. In this beautiful inquiry into time and its milestones, he shares his interest and insights with his readers. Refreshingly reasoned and absorbing, the book asks and answers the three major questions that define the approaching calendrical event. First, what exactly is this concept of a millennium and how has its meaning shifted? How did the name for a future thousand-year reign of Jesus Christ on earth get transferred to the passage of a secular period of a thousand years in current human history? When does the new millennium really begin: January 1, 2000, or January 1, 2001? (Although seemingly trivial, the debate over this issue tells an intriguing story about the cultural history of the twentieth century.) And why must our calendars be so complex, leading to our search for arbitrary regularity, including a fascination with millennia? This revised edition begins with a new and extensive preface on a key subject not treated in the original version. As always, Gould brings into his essays a wide range of compelling historical and scientific fact, including a brief history of millennial fevers, calendrical traditions, and idiosyncrasies from around the world; the story of a sixth-century monk whose errors in chronology plague us even today; and the heroism of a young autistic man who has developed the extraordinaryability to calculate dates deep into the past and the future.

Earth science - Earth science (also known as geoscience, the geosciences or the Earth Sciences), is an all-embracing term for the sciences related to the planet Earth. It is arguably a special case in planetary science, being the only known life-bearing planet.

Gorath - Gorath (妖星ゴラス - Yosei Gorasu) is a 1962 science fiction tokusatsu produced by Toho Studios which depicts a runaway star on a collision course with Earth. Unlike most other impact event stories, in which mankind must abandon the Earth (When Worlds Collide) or destroy the threat (Deep Impact, Armageddon), Gorath sees humanity attempt to avert disaster by disengaging Earth from its own orbit around the Sun.
