Astronomy History

No direct explanation is given for the origin and nature of the luminous bodies, the sun, the planets, and the stars. Because the Sumerians regarded the moon-god, who went by the names Sin and Nanna, as the son of the air-god Enlil, it does not seem unreasonable to suggest that they saw the moon as a bright, air-like body fashioned from the atmosphere. As the sun-god Utu and the Venus goddess Inanna are always referred to as children of the moon-god, these luminous bodies were probably imagined as having come from the moon after the latter had been formed from the atmosphere.

Mapping the Heavens provides a tour of the "greatest hits" of cosmological discoveries - the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is at the forefront of the research - an astrophysicist who literally creates maps of invisible matter in the universe.

In 1957 Sputnik launched toward the stars. President Kennedy then announced that the United States would send men to the Moon and then return them to Earth.These pivotal moments sparked an unequaled bound forward in human innovation and scientific exploration. At the heart of this momentous time were the men and women working behind the scenes. Scientists, historians, and astronomers share their memories and contributions from this unparalleled era in essays told in their own words.

Sarah Cruddas has been looking to the skies her entire life. Her childhood was spent staring at the moon and hearing stories of the space race, and she worked in a fruit factory to fund her love of the subject. Her subsequent career studying astrophysics and becoming a television host and space journalist has seen her report on space exploration and chase launches across the world. In Look Up Sarah explains why she has always been a passionate advocate for why space should matter - to everyone.

¿Alguna vez has levantado la vista al cielo en una noche estrellada y te has dejado llevar por la imaginación? Igual en ese momento te has trasladado a mundos que van más allá de lo que podemos imaginar en la Tierra. Algunos con vida, puede que inteligente, y otros completamente inhóspitos e infernales. O quizá simplemente te has preguntado cuántas estrellas hay en la Vía Láctea.

Nothing captivates the human imagination like the vast unknowns of space. Ancient petroglyphs present renderings of the heavens, proof that we have been gazing up at the stars with wonder for thousands of years. Since then, mankind has systematically expanded our cosmic possibilities. What were once flights of fancy and dreams of science fiction writers have become nearly routine. Space travel is a sometimes heroic, sometimes humorous, and always dangerous journey fraught with perils. Space Oddities brings unknown, offbeat, and obscure stories of space to life.

In the early 17th century, Galileo broke free from the hold of ancient Platonic and Aristotelian philosophy. He drastically changed the framework through which we view the natural world when he asserted that we should base our theory of reality on what we can observe rather than pure thought. In the process, he invented what we would come to call science. This set the stage for all the breakthroughs that followed - from Kepler to Newton to Einstein.

The airplane changed the course of history. Above all, it changed the history of the United States. When the Wright brothers invented their flying machine, Americans lived in a nation of two dimensions, circumscribed by lines drawn on a conventional map. A century later, their nation existed - in fact, reigned - in three dimensions. Two million Americans slipped the surly bonds of earth daily, carried aloft by aircraft operating in every part of the world.

As smartphones, supercomputers, supercolliders, and AI propel us into an ever more unfamiliar future, How to Speak Science takes us on a rollicking historical tour of the greatest discoveries and ideas that make today's cutting-edge technologies possible. Wanting everyone to be able to "speak" science, YouTube science guru Bruce Benamran explains - as accessibly and wittily as in his acclaimed videos - the fundamental ideas of the physical world: matter, life, the solar system, light, electromagnetism, thermodynamics, special and general relativity, and much more.

In 1977 a group of scientists, artists and writers gathered in a house in Ithaca, New York to work on the most important mixtape ever conceived. It wasn’t from one person to another - it was from Earth to the cosmos. When NASA sent Voyagers 1 and 2 on a grand tour of the outer planets, they knew the ultimate fate of these plucky probes would be to drift forever in the unimaginable void of interstellar space.

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 Search of a Theory of Everything takes listeners on an adventurous journey through space and time on a quest for a unified "theory of everything" by means of a rare and agile interplay between the natural philosophies of influential ancient Greek thinkers and the laws of modern physics.

In Apollo's Legacy, space historian Roger D. Launius explores the many-faceted stories told about the meaning of the Apollo program and how it forever altered American society. The Apollo missions marked the first time human beings left Earth's orbit and visited another world, and thus they loom large in our collective memory. Many have detailed the exciting events of the Apollo program, but Launius offers unique insight into its legacy as seen through multiple perspectives.

Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes.

Come spiegare l'astronomia in termini chiari ed esaurienti? Questo libro, insieme rigoroso e divulgativo, è con disegni, foto e brevi testi di approfondimento un "abbicì" dell'astronomia che aiuta a familiarizzare con stelle, pianeti, eclissi, galassie e il mondo extragalattico.

Since the first humans looked up and saw the sun swallowed by darkness, our species has been captivated by solar eclipses. Astronomer and anthropologist Anthony Aveni explains the history and culture surrounding solar eclipses, from prehistoric Stonehenge to Babylonian creation myths, to a confirmation of Einstein's theory of general relativity, to a spectacle that left New Yorkers in the moon's shadow, to future eclipses that will capture human imaginations.

The Scientific Revolution of the 17th century has often been called a decisive turning point in human history. It represents, for good or ill, the birth of modern science and modern ways of viewing the world. In What Galileo Saw, Lawrence Lipking offers a new perspective on how to understand what happened then, arguing that artistic imagination and creativity as much as rational thought played a critical role in creating new visions of science and in shaping stories about eye-opening discoveries.

On June 6, 1761, the world paused to observe a momentous occasion: the first transit of Venus between the earth and the sun in more than a century. Through that observation, astronomers could calculate the size of the solar system - but only if they could compile data from many different points of the globe, all recorded during the short period of the transit. Fortunately, transits of Venus occur in pairs: eight years later, the scientists would have another opportunity to succeed.

On June 3, 1769, the planet Venus briefly passed across the face of the sun in a cosmic alignment that occurs twice per century. Anticipation of the rare celestial event sparked a worldwide competition among aspiring global superpowers, each sending their own scientific expeditions to far-flung destinations to time the planet’s trek.

From designers to engineers, and even communication specialists and the builders who assembled these towering rockets, hundreds of thousands of people worked on getting humans to the moon, yet only a few have been recognized for their contributions. George D. Morgan sets the record straight by giving these forgotten figures of space travel their due.
