Earths Astronomy

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.

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.

On August 21, 2017, more than 10 million Americans will experience an awe-inspiring phenomenon: the first total eclipse of the sun in America in almost 40 years. In Sun Moon Earth, astronomer Tyler Nordgren illustrates how this most seemingly unnatural of natural phenomena was transformed from a fearsome omen to a tourist attraction. From the astrologers of ancient China and Babylon to the high priests of the Maya, Sun Moon Earth takes us around the world to show how different cultures interpreted these dramatic events.

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 (M.Sc., Fellow of Geoscientists, Canada) and educator, who specializes in translating scientific material for the non-expert.

Today, Elon Musk's SpaceX is building one human-rated reusable spacecraft every week designed to send 100 colonists to Mars on each voyage. With this brilliant plan, SpaceX aims to colonize the Red Planet. This is not science fiction. These ships are in construction every day at a startling pace in order to make humanity a multiplanetary species, beginning this decade. Departing Earth Forever is the first manual written to and for Martian colonists—and for humankind back on the home planet witnessing this single most historic and momentous event in human history.

With unique and unprecedented access, intrepid space journalist David Ariosto delivers a behind-the-scenes look into the key players across five continents that are now dominating this current age of space exploration, as well as the key policymakers and frontier technologies that are making it all possible.

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.

This “accessible and always entertaining” (Booklist) combination of history, pop science, and in-depth reporting offers a fascinating account of the asteroids that hit Earth long ago and those streaming toward us now, as well as how prepared we are against asteroid-caused catastrophe.

Why is there winter in the Southern Hemisphere at the same time there is summer in the Northern Hemisphere? Here is an explanation of how the position of Earth in relation to the sun causes seasons and the wonders that come with each one of them. Summer. Autumn. Winter. Spring comes again. Year after year, the seasons repeat themselves.

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.

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.

We have long fantasized about finding life on planets other than our own. Yet even as we become aware of the vast expanses beyond our solar system, it remains clear that Earth is exceptional. The question is: Why? In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is what makes it uniquely able to support life, and it is nothing short of luck that made such conditions possible. The four-billion-year stretch of good weather that our planet has experienced is statistically so unlikely that chances are slim that we will ever encounter intelligent extraterrestrial others.

Em outubro de 2017, cientistas de um dos maiores observatórios espaciais do mundo — localizado no topo de um vulcão dormente no Havaí — detectaram um objeto transitando por nosso sistema solar. A primeira hipótese foi a de que se tratava de um mero asteroide, como tantos outros que cruzaram e seguem cruzando nossa galáxia. Mas os dados coletados pelo telescópio Pan-STARRS1 revelaram detalhes curiosos, e bem anômalos, no comportamento desse visitante.
