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.

"Siamo soli nell'universo?" è una domanda che lascia un senso di vertigine a chiunque. Amedeo Balbi, nato all'alba degli anni '70, se la pone fin da quando era bambino. All'epoca erano tanti gli stimoli che potevano suscitare questo genere di curiosità in una mente giovane ed entusiasta: il ricordo recente della corsa allo spazio culminata con lo sbarco sulla Luna nel 1969, ma anche la serie Spazio 1999 del '76, Guerre stellari del '77, Goldrake del '78... Oggi, a distanza di quarant'anni, Balbi è un astrofisico.

On April 24, 1990, the Space Shuttle Discovery lifted off from Kennedy Space Center on the Space Shuttle Program’s 35th mission, but this was no ordinary mission. In its payload bay, Discovery was carrying the Hubble Space Telescope, with the objective of putting the telescope into orbit.

In the first book to critically assess the major consequences of space activities from their origins in the 1940s to the present and beyond, Daniel Deudney argues in Dark Skies that the major result of the "Space Age" has been to increase the likelihood of global nuclear war, a fact conveniently obscured by the failure of recognize that nuclear-armed ballistic missiles are inherently space weapons.

Did you know that humans have only been able to study five percent of the universe? The other 95 percent of our universe is invisible! There are several parts of the universe that we haven't seen yet, as light from there hasn't reached us yet! If the mechanisms of space pique your interest, you have come to the right place.

In her graceful, compelling style, Dava Sobel chronicles the history of the Copernican Revolution, relating the story of astronomy from Aristotle to the Middle Ages. In its midst will be her play, And the Sun Stood Still, imagining the dialogue that would have transpired between Rheticus and Copernicus in their months together. As she achieved with her bestsellers Longitude and Galileo's Daughter, Sobel expands the bounds of science writing, giving us an unforgettable portrait of scientific achievement.

Not long ago, the Solar System was the only example of a planetary system - a star and the bodies orbiting it - that we knew. Now, we know thousands of planetary systems, and have even been able to observe planetary systems at the moment of their birth.

This new edition brings the latest astronomical discoveries together with cutting-edge teaching and learning strategies designed specifically to improve student learning and retention.

Is the story about the Star in the East true? And, if so, what exactly was the “star”? While Sir Patrick cannot give a definitive answer, in The Star of Bethlehem, he looks at various astronomical theories and comes up with a possible answer of his own. Who has not heard of the Star in the East? It is one of the most famous stories in the Bible, and tells us how the Wise Men came to Bethlehem to seek out the infant Jesus.

Nel suo inconfondibile stile divulgativo, Adrian Fartade ci invita a seguirlo oltre le "colonne d'Ercole" della nostra regione del Sistema solare, cioè la Fascia di Asteroidi, lasciandoci così conquistare da Giove, gigante gassoso tormentato da enormi cicloni ipnotici, e da Saturno, con il suo sistema complesso e affascinante di anelli e tempeste esagonali. Questa cavalcata emozionante prosegue poi verso Urano, il pianeta piegato sul fianco con archi colossali di ghiaccio e roccia, e Nettuno, coperto da nuvole di ammoniaca gelata che gettano ombre di centinaia di chilometri.

In this book, John Moffat shares the history of black holes and presents the latest research into these mysterious celestial objects, including the astounding results from gravitational wave detection and the shadow of the black hole.

Carl Edward Sagan (November 9, 1934-December 20, 1996), born in Brooklyn, NY, was an American astronomer and astrophysicist. His best-known scientific contribution was his research on the possibility of extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by exposure to light. The following is a lecture Sagan gave in 1977 during which he discussed the place, scale and geometry of earth–the third planet from the Sun, formed 4.5 billion years ago–in our solar system.

In 1869, a great mystery was born. As astronomers observed a total solar eclipse, for the first time they saw the faint glow of the solar corona, the sun's outer atmosphere. Measurements of a previously unknown wavelength that made up this solar light sparked hot debate among scientists, but it was another 60 years before they discovered that this wavelength was in fact iron being burned at a staggering three million degrees Celsius. With the sun's surface only 6,000 degrees, this shouldn't be possible.

W czasach Kopernika nic nie wskazywało na to, że do największej naukowej rewolucji dojdzie w Europie. O gwiazdach Chińczycy i Arabowie wiedzieli więcej, ale to my jako pierwsi zrozumieliśmy, jakie jest miejsce Ziemi w kosmosie. Ktoś może powiedzieć, że to przede wszystkim zasługa Keplera, Galileusza, Newtona–ale gdybyśmy zapytali tych panów o zdanie, wskazaliby na dzieło bardzo skromnego, genialnego uczonego, który by pracować w spokoju nad swoim odkryciem, zaszył się na skraju Europy.

We now know that the universe is mostly dark, made up of particles and forces undetectable by our most powerful telescopes. The discovery signaled a Copernican-like revolution in astronomy: not only are we not the center of the universe, neither is the stuff of which we're made. Vera Rubin played a pivotal role in this discovery. By showing that some astronomical objects seem to defy gravity, Rubin helped convince the scientific community of the possibility of dark matter. In Bright Galaxies, Dark Matter, and Beyond, Ashley Jean Yeager tells the story of Rubin's life and work.

The moon contains a wealth of natural resources. So, as the Earth's supplies have begun to dwindle, it is no surprise that the world's superpowers and wealthiest corporations have turned their eyes to the stars. As this new Space Race begins, A.C. Grayling asks: who, if anyone, owns the moon? Or Mars? Or other bodies in near space? And what do those superpowers and corporations owe to Planet Earth and its inhabitants as a whole?

It takes a certain amount of courage to step beyond one's day-to-day experiments and look at the big picture - and the origin of the Moon is a big picture question par excellence. Perhaps it makes sense that William Hartmann, one of the two scientists who unraveled the Moon's biggest mystery, is not only a scientist but also a part-time artist and science fiction writer. It took someone with an artist's eye and a fiction writer's speculative temperament to see the big picture....
