Astronomy History

In the 1940s and '50s, when the newly minted Jet Propulsion Laboratory needed quick-thinking mathematicians to calculate velocities and plot trajectories, they didn't turn to male graduates. Rather, they recruited an elite group of young women who, with only pencil, paper, and mathematical prowess, transformed rocket design, helped bring about the first American satellites, and made the exploration of the solar system possible.

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.

July 20, 1969. Astronauts Neil Armstrong and Edwin “Buzz” Aldrin left humanity’s first footprints on the Moon. The plaque they left behind reads, “Here men from the planet Earth first set foot upon the Moon, July 1969, A.D. We came in peace for all mankind.” But was the Apollo 11 moon landing mission really a global endeavor? How did people outside the United States view these “rocket men”? Against the political backdrop of the Cold War between the US and the Soviet Union, was it, indeed, “For all mankind”?

It was a time of bold new technology, historic moments, and international jousting on the final frontier. But it was also a time of human drama, of moments less public but no less dramatic in the lives of those who made the golden age of space flight happen. These are the moments and the lives that Into That Silent Sea captures, a book that tells the intimate stories of the men and women, American and Russian, who made the space race their own and gave the era its compelling character.

July 1967: At the Moscow Air Show, the Soviets unveiled six new state-of-the-art aircraft. From among this lineup of new fighters and interceptors stood the Mikoyan-Gurevich MiG-25 - purportedly capable of outrunning and outmaneuvering any aircraft in NATO’s inventory. Yet even before its public appearance in Moscow, the MiG-25 had been a grave concern for Western analysts.

In a race against time, the Apollo program challenged our scientific capabilities and redefined the boundaries of humanity. To celebrate NASA’s 60 years of exploration, Seeker went back in time to relive each Apollo mission. Listen along as Seeker dives into the whole story from its WWII origins to its present day possibilities available for the first time in audio.

It has been argued that science fiction (SF) gives a kind of weather forecast - not the telling of a fortune but rather the rough feeling of what the future might be like. The intention in this audiobook is to consider some of these bygone forecasts made by SF and to use this as a prism through which to view current developments in science and technology.

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.

In 1929, Edwin Hubble announced the greatest discovery in the history of astronomy since Galileo first turned a telescope to the heavens. The galaxies, previously believed to float serenely in the void, are in fact hurtling apart at an incredible speed: the universe is expanding. This stunning discovery was the culmination of a decades-long arc of scientific and technical advancement.

Have you ever wondered how we came into being? Have you ever looked in the sky and marveled at the stars? This introduction to space gives you a foundation to explore whatever sparks your interest within this magnificent universe of ours. All this and more is available in this astronomy book. This book on astronomy is a perfect introduction to finding the truth out about wormholes, black holes, and the planets that surround us. Have you ever wondered what is out there? What about if there are more planets out there that we don't know about?

As technological advances and the creation of flying aircraft became realities, the sighting of UFOs increased, as did the interest in potential contact with aliens. It would hardly be groundbreaking for scientists in the 20th century to have a lunchtime discussion in which the search for extraterrestrial life arises, and the question of where it might reside is innocuous enough. However, a furor was created somewhat innocently when physicist Enrico Fermi voiced his “casual lunchtime remark” in the presence of colleagues in 1950.

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

El relato del conocimiento del universo inabarcable, desde la mirada al cielo con el ojo desnudo hasta las sondas enviadas a años luz de la Tierra: una historia que tiene más de 3.600 años de antigüedad.La tarea de resumir más de tres milenios de investigaciones sobre el cielo parece imposible, más difícil aún parece presentarla de modo que pueda ser conocido por cualquier tipo de oyente, independientemente del conocimiento del mismo.

La tarea de resumir más de tres milenios de investigaciones sobre el cielo parece imposible, más difícil aún parece presentarla de modo que pueda ser conocido por cualquier tipo de oyente, y de modo que se disfrute con el descubrimiento de los cuerpos que pueblan el espacio y con la historia de los grandes hombres que hicieron avanzar la astronomía hasta sacar al hombre y a la Tierra, del centro del universo y colocarlo en un lugar periférico en la orilla del cosmos. Breve historia de la astronomía emprende esta tarea y consigue desplegar ante nosotros el universo.

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.

Highlighting men and women across the globe who have dedicated themselves to pushing the limits of space exploration, this book surveys the programs, technological advancements, medical equipment, and automated systems that have made space travel possible. Beginning with the invention of balloons that lifted early explorers into the stratosphere, Ted Spitzmiller describes how humans first came to employ lifting gasses such as hydrogen and helium.

During the Age of Exploration, Native American tribes fell victim to European conquerors seeking legendary cities made of gold and other riches, attempts that were often being made in vain. And yet, of all the empires that were conquered across the continent, the one that continues to be most intimately associated with legends of gold and hidden riches is the Inca Empire.

The Cold War is usually thought of in terms of fear, potential nuclear war, and espionage. While these were elements of the years between the end of World War II and the 1990s, the competition between the US and the USSR had some real benefits. Perhaps, the best and most impressive accomplishments during this time resulted from the Space Race.

Spaceflight is one of the greatest human achievements of the 20th century. The Soviets launched Sputnik, the first satellite, in 1957; less than 12 years later, the American Apollo astronauts landed on the moon.

In 1910, Mary Acworth Evershed (1867-1949) sat on a hill in southern India staring at the moon as she grappled with apparent mistakes in Dante's Divine Comedy. Was Dante's astronomy unintelligible? Or was he, for a man of his time and place, as insightful as one could be about the sky? As the 20th century began, women who wished to become professional astronomers faced difficult cultural barriers, but Evershed joined the British Astronomical Association and, from an Indian observatory, became an experienced observer of sunspots, solar eclipses, and variable stars.
