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.

Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces listeners to the science of near-Earth objects - its history, applications, and ongoing quest to find near-Earth objects before they find us.

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.

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.

Some see dust as dull stuff, useless at best, and sneeze-inducing at worst. But in the hands of writer Hannah Holmes, dust becomes a dazzling and mysterious force. As Holmes says, dust is a messenger, and air is its medium. And by the end of this fascinating journey through The Secret Life of Dust, we cannot help but agree.

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.

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.

Young listeners will learn about the basic patterns of the sun and earth and what causes day and night.

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.

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.

For anyone who has ever looked up at the stars and wondered what it all means, Issac Asimov’s Guide to Earth and Space is indispensible. Issac 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? Perplexed by the Big Bang? Bewildered by black holes?

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.

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.

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.
