  carl sagan telescope: Murmurs of Earth Carl Sagan, 2013-04-02 In 1977, two extraodinary spacecraft called Voyager were launched to the stars. Affixed to each Voyager craft was a gold-coated copped phonograph record as a message to possible extra-terrestrial civilizations that might encounter the spacecraft in some distant space and time. Each record contained 118 photographs of our planet; almost 90 minutes of the world's greatest music; an evolutionary audio essay on The Sounds of Earth; and greetings in almost sixty human languages (and one whale language). This book is an account, written by those chiefly responsible for the contents of the Voyager Record, of why they did it, how they selected the repertoire, and precisely what the record contains.

  carl sagan telescope: Sidereus Nuncius, Or The Sidereal Messenger Galileo Galilei, 1989-04-15 Sidereus Nuncius (usually Sidereal Messenger, also Starry Messenger or Sidereal Message) is a short astronomical treatise (or pamphlet) published in New Latin by Galileo Galilei in March 1610. It was the first published scientific work based on observations made through a telescope, and it contains the results of Galileo's early observations of the imperfect and mountainous Moon, the hundreds of stars that were unable to be seen in either the Milky Way or certain constellations with the naked eye, and the Medicean Stars that appeared to be circling Jupiter.[1] The Latin word nuncius was typically used during this time period to denote messenger; however, albeit less frequently, it was also interpreted as message. While the title Sidereus Nuncius is usually translated into English as Sidereal Messenger, many of Galileo's early drafts of the book and later related writings indicate that the intended purpose of the book was simply to report the news about recent developments in astronomy, not to pass himself off solemnly as an ambassador from heaven.[2] Therefore, the correct English translation of the title is Sidereal Message (or often, Starry Message).--Wikiped, Nov/2014.

  carl sagan telescope: Waiting for Contact Lawrence Squeri, 2016-08-31 A cogent, engaging history of humanity's most ambitious quest--seeking outward for other minds.--David Brin, author of Existence A fascinating perspective on humankind's obsession for knowing if there is anyone else out there.--Gerrit L. Verschuur, author of The Invisible Universe: The Story of Radio Astronomy Squeri has written what will likely be the definitive history of the early days of SETI that includes profiles of some of its leading characters.--Ben Zuckerman, coeditor of Extraterrestrials: Where Are They? An insightful history that explores the scientific foundations of the modern-day search for our place in the cosmos. Waiting for Contact delivers unparalleled access to the inner history of SETI and invites us to ride along on the journey to answer one of science's ultimate questions: Are we alone?--Douglas Vakoch, president, METI International Waiting for Contact is a balanced account, telling the tale of the search for extraterrestrial intelligence without the overpromise usually trumpeted by enthusiastic proponents and the hyperventilation so commonly added by UFO enthusiasts. If you are simply interested in the history, unvarnished by an agenda, you'll enjoy this book.--Don Lincoln, author of Alien Universe: Extraterrestrial Life in Our Minds and in the Cosmos Imagine a network of extraterrestrials in radio contact with each other across the universe, superior beings who hail from advanced civilizations quadrillions of miles away, just waiting for Earth to tune in. Some people believe it’s only a matter of time before we discover the right station. Waiting for Contact tells the story of the Search for Extraterrestrial Intelligence (SETI) movement, which emerged in 1959 as astronomers began using radio telescopes to listen for messages from space. New technological developments turned what once was speculation into science. Boosted by support from Frank Drake, Philip Morrison, Carl Sagan, and the genre of science fiction, the SETI movement gained followers and continues to capture imaginations today. In this one-of-a-kind history, Lawrence Squeri looks at the people, reasons, goals, and mindsets behind SETI. He shows how it started as an expression of the times, a way out of Cold War angst with hope for a better world. SETI's early advocates thought that with guidance from technically and ethically advanced outsiders, humanity might learn how to avoid horrors like nuclear annihilation and societal collapse from overpopulation. Some hoped that good news from outer space might reveal a cure for cancer or even the secret of immortality. Squeri also describes the challenges SETI has faced over the years: the struggle to be taken seriously by the scientific community and by NASA, competition for access to radio telescopes, perpetual lack of funding, and opposition from influential politicians. He covers the rise and fall of Soviet SETI and the few rare meetings between Soviet and American astronomers. Despite many setbacks, the movement pressed forward with the aid of private donations and developed outreach programs. Volunteers can now help search for new civilizations on their personal computers by joining the SETI@Home project. Today, SETI researchers continue to see themselves as explorers. They often identify with Columbus, and just as Columbus never realized the full implications of his discovery, we cannot predict what will happen if contact is made. This book points out that if, against all expectations, the embattled SETI movement finally succeeds, the long-awaited first signal picked up by its radio antennas will usher the greatest shift in human history. A new adventure will begin. Lawrence Squeri is professor emeritus of history at East Stroudsburg University.
  carl sagan telescope: The Sagan Conspiracy Donald L. Zygutis, 2016-11-21 Mainstream SETI scientists and ancient alien theorists don’t agree on much, but one opinion they share is that the undisputed authority on the possibility of alien existence was the late Carl Sagan (1934—1996), whose voluminous writings on the subject have had a profound influence on ETI research.But how many Carl Sagan fans know that while the renowned scientist was at Stanford University, he produced a controversial paper, funded by a NASA research grant, that concludes ancient alien intervention may have sparked human civilization? Author Donald Zygutis lays out a compelling case that points to a cover-up by the Pentagon and NASA, who may have buried it soon after it was written. How significant is the Stanford Paper? The answer may lie in another question: How would a science-backed theory and search strategy to guide the discovery of alien artifacts among our own ancient civilizations impact the worldwide institutions of government, religion, and culture?Recently rediscovered by the author, Sagan’s lost Stanford paper is the central theme of The Sagan Conspiracy. Groundbreaking research and paradigm-changing material challenges conventional thinking about the People’s Scientist—and maybe even the origins of human society. Sagan even conceived of the likelihood that the ancient Sumerian civilization had been visited and influenced by beings from other worlds as evidenced by ancient manuscripts, among other artifacts.As we celebrate the 20-year anniversary of Carl’s death, The Sagan Conspiracy is sure to fundamentally alter how the world thinks about extraterrestrials.

Praise for Billions & Billions “[Sagan’s] writing brims with optimism, clarity and compassion.”—Ft. Lauderdale Sun-Sentinel “Sagan used the spotlight of his fame to illuminate the abyss into which stupidity, greed, and the lust for power may yet dump us. All of those interests and causes are handsomely represented in Billions & Billions.”—The Washington Post Book World “Astronomer Carl Sagan didn’t live to see the millennium, but he probably has done more than any other popular scientist to prepare us for its arrival.”—Atlanta Journal & Constitution “Billions & Billions can be interpreted as the Silent Spring for the current generation. . . . Human history includes a number of leaders with great minds who gave us theories about our universe and origins that ran contrary to religious dogma. Galileo determined that the Earth revolved around the Sun, not the other way around. Darwin challenged Creationism with his Evolution of Species. And now, Sagan has given the world its latest challenge: Billions & Billions.”—San Antonio Express-News “[Sagan’s] inspiration and boundless curiosity live on in the gift of his work.”—Seattle Times & Post-Intelligencer “Couldn’t stay awake in your high school science classes?

  carl sagan telescope: Gerard P. Kuiper and the Rise of Modern Planetary Science Derek W. G. Sears, 2019-03-26 Astronomer Gerard P. Kuiper ignored the traditional boundaries of his subject. Using telescopes and the laboratory, he made the solar system a familiar, intriguing place. “It is not astronomy,” complained his colleagues, and they were right. Kuiper had created a new discipline we now call planetary science. Kuiper was an acclaimed astronomer of binary stars and white dwarfs when he accidentally discovered that Titan, the massive moon of Saturn, had an atmosphere. This turned our understanding of planetary atmospheres on its head, and it set Kuiper on a path of staggering discoveries: Pluto was not a planet, planets around other stars were common, some asteroids were primary while some were just fragments of bigger asteroids, some moons were primary and some were captured asteroids or comets, the atmosphere of Mars was carbon dioxide, and there were two new moons in the sky, one orbiting Uranus and one orbiting Neptune. He produced a monumental photographic atlas of the Moon at a time when men were landing on our nearest neighbor, and he played an important part in that effort. He also created some of the world’s major observatories in Hawai‘i and Chile. However, most remarkable was that the keys to his success sprang from his wartime activities, which led him to new techniques. This would change everything. Sears shows a brilliant but at times unpopular man who attracted as much dislike as acclaim. This in-depth history includes some of the twentieth century’s most intriguing scientists, from Harold Urey to Carl Sagan, who worked with—and sometimes against—the father of modern planetary science. Now, as NASA and other space agencies explore the solar system, they take with them many of the ideas and concepts first described by Gerard P. Kuiper.

  carl sagan telescope: The Stardust Revolution Jacob Berkowitz, 2022-02-15 In 1957, as Americans obsessed over the launch of the Soviet Sputnik satellite, another less noticed space-based scientific revolution was taking off. That year, astrophysicists solved a centuries-old quest for the origins of the elements, from carbon to uranium. The answer they found wasn’t on Earth, but in the stars. Their research showed that we are literally stardust. The year also marked the first conference that considered the origin of life on Earth in an astrophysical context. It was the marriage of two of the seemingly strangest bedfellows—astronomy and biology—and a turning point that award-winning science author Jacob Berkowitz calls the Stardust Revolution. In this captivating story of an exciting, deeply personal, new scientific revolution, Berkowitz weaves together the latest research results to reveal a dramatically different view of the twinkling night sky—not as an alien frontier, but as our cosmic birthplace. Reporting from the frontlines of discovery, Berkowitz uniquely captures how stardust scientists are probing the universe’s physical structure, but rather its biological nature. Evolutionary theory is entering the space age. From the amazing discovery of cosmic clouds of life’s chemical building blocks to the dramatic quest for an alien Earth, Berkowitz expertly chronicles the most profound scientific search of our era: to know not just if we are alone, but how we are connected. Like opening a long-hidden box of old family letters and diaries, The Stardust Revolution offers us a new view of where we’ve come from and brings to light our journey from stardust to thinking beings.

  carl sagan telescope: Analyzing the Physics of Radio Telescopes and Radio Astronomy Yeap, Kim Ho, Hirasawa, Kazuhiro, 2020-02-07 In the field of astrophysics, modern developments of practice are emerging in order to further understand the spectral information derived from cosmic sources. Radio telescopes are a current mode of practice used to observe these occurrences. Despite the various accommodations that this technology offers, physicists around the globe need a better understanding of the underlying physics and operational components of radio telescopes as well as an explanation of the cosmic objects that are being detected. Analyzing the Physics of Radio Telescopes and Radio Astronomy is an essential reference source that discusses the principles of the astronomical instruments involved in the construction of radio telescopes and the analysis of cosmic sources and celestial objects detected by this machinery. Featuring research on topics such as electromagnetic theory, antenna design, and geometrical optics, this book is ideally designed for astrophysicists, engineers, researchers, astronomers, students, and educators seeking coverage on the operational methods of radio telescopes and understanding the physical processes of radio astronomy.
  carl sagan telescope: A for Andromeda Fred Hoyle, John Elliot, 1975 From two hundred light years across the universe comes a message of terror. Ten years from now, a new radio telescope picks up from the constellation of Andromeda a complex series of signals which prove to be a programme for a giant computer. When the computer begins to relay the information it receives from Andromeda the project assumes a vital importance, scientists find themselves possessing knowledge previously unknown to mankind, knowledge that could threaten the security of human life itself.Sir Fred Hoyle was Plumian Professor of Astronomy and Experimental Philosophy at Cambridge University while John Elliott was a novelist, from their collaboration comes a work of major scientific interest and a remarkably original story that is as enthralling today.
