Earths Astronomy

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.

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.

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.

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.

Ein Blick auf die Erforschung außerirdischen Lebens, die unser Verständnis des Kosmos verändert. Seit Tausenden von Jahren fragen sich die Menschen, ob sie allein im Weltall sind. Zum ersten Mal können wir nun auch die entsprechende Technologie nutzen, um das zu untersuchen. Die Frage nach anderem Leben im Universum sollte eine klare Antwort haben: ja oder nein. Aber wenn man versucht, anderswo Leben zu finden, stellt man fest, dass es nicht so einfach ist. Wie kann man es über kosmische Entfernungen hinweg finden? Was ist eigentlich Leben?

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.

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.

Wissensvermittlung mit Witz und Charme von Erfolgsautor Bill Bryson. Wie war das eigentlich mit dem Urknall? Warum starben die Dinosaurier aus? Was wiegt die Erde? Und wie ist das überhaupt möglich - die Erde zu wiegen? Erfolgsautor Bill Bryson nimmt mit auf eine atemberaubende Reise durch Zeit und Raum, berichtet über die Wunder des Universums, über die Erde und die Entstehungsgeschichte des Menschen. Dieser faszinierende Streifzug durch die Naturwissenschaften ist wie gemacht für alle, die endlich mehr über die Welt wissen wollen.

Apollo 15 command module pilot Al Worden was one of the highest-profile personalities among the Apollo astronauts, renowned for his outspokenness and potent views but also recognized as a warm and well-liked person who devoted much of his life after retiring from NASA to sharing his spaceflight experiences.

In the mid-1990s, astronomers made history when they detected three planets orbiting stars in the Milky Way. The planets were nothing like Earth, however: They were giant gas balls like Jupiter or Saturn. More than 500 planets have been found since then, yet none of them could support life. Now, armed with more powerful technology, planet hunters are racing to find a true twin of Earth. Science writer Michael Lemonick has unique access to these exoplaneteers, as they call themselves, and Mirror Earth unveils their passionate quest.

Los Angeles, 1930s: Everyone knows that rockets are just toys, the stuff of cranks and pulp magazines. Nevertheless, an earnest engineering student named Frank Malina sets out to prove the doubters wrong. With the help of his friend Jack Parsons, a grandiose and occult-obsessed explosives enthusiast, Malina embarks on a journey that takes him from junk yards and desert lots to the heights of the military-industrial complex.

In Beyond Earth, the authors offer groundbreaking research and argue persuasively that not Mars but Titan - a moon of Saturn with a nitrogen atmosphere, a weather cycle, and an inexhaustible supply of cheap energy, where we will be able to fly like birds in the minimal gravitational field - offers the most realistic and thrilling prospect of life without support from Earth.

In this intriguing recording, Professor Emeritus Timothy Ferris—one of the world's most respected science writers—explores man's search for life elsewhere in the universe. Ferris combines new discoveries about the origins of life as we know it on Earth with recent revelations about the sun's planets and their moons. Ferris explains why many scientists are convinced that life is abundant throughout the cosmos, and he considers how one day radio telescopes may be used to connect us to an intergalactic Internet and link us to alien civilizations in the far reaches of the universe.

Naturwissenschaft leicht erzählt. Die Schwerkraft kann man mit einer Pfannkuchentorte erklären und die Relativitätstheorie mit dem Bauch einer dicken Katze. Klingt irre? Ist es auch! Vor allem, weil es funktioniert. Mit Begeisterung erzählt Johan Olsen vom Urknall über die Entstehung des Lebens bis zum Menschen. Er erklärt Atome, Relativitätstheorie, Moleküle und Proteine, also was man alles braucht um eine Welt zu erschaffen mittels humorvoller Veranschaulichungen - und warum der Mensch vielleicht doch nicht die Krone der Schöpfung ist.

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.

Stay curious with Dr. Mae Jemison, the first African American woman to travel to space and participate in NASA’s space program.

This is volume two of our series, and our astronaut is once again aboard a spaceship heading for deep space to avoid the self-destruction of Earth. Join us as nearly 200 of Earth's inhabitants flee for safety in a spaceship called The Ark.

The secrets of science meet the drama of the high seas. Amir D. Aczel - the distinguished science writer behind God's Equation and Mystery of the Aleph - turns detective as he uncovers the fascinating story of the invention of the compass.

In the early days of civilization, we knew nothing about the moon. It was considered as a god chasing the sun in an endless race through the sky. Today, we know much more than our ancestors. We can speculate on the creation of the moon and what the Earth would be without the moon. It turns out that our moon has played a much more important role in life development than anyone would have thought.

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.
