Astrotourism : Star Gazers, Eclipse Chasers, and the Dark Sky Movement
In the span of a single lifetime, light pollution stemming from Artificial Light At Night (ALAN) has severed our connection with the stars that we've had since the dawn of time. With the nocturnal biosphere significantly altered, light's anthropogenic influence has compelled millions of people to seek out the last remaining dark skies. This book explores the burgeoning growth of the astrotourism market, identifies star seeker trends, how the stars have shaped civilizations, and the budding space tourism industry. Discover ways to develop a destination for those who will cater to the astrotourist, share the night with guests, how to find customers, and the 2024 Great North American Eclipse. Meteor storms, eclipses, auroras, and other celestial phenomena have lured travellers for years. Here, the author expands the field of astrotourism with the inclusion of astronomical clocks, megaliths, and sundials, which are used to track the movement of the stars.
Celestial Shadows : Eclipses, Transits, and Occultations
Much of what is known about the universe came from the study of celestial shadows. This book looks in detail at the way eclipses and other celestial shadows have given us amazing insights into the nature of the objects in our solar system and how they are even helping us discover and analyze planets that orbit stars other than our Sun. A variety of eclipses, transits, and occultations of the mooons of Jupiter and Saturn, Pluto and its satellite Charon, asteroids and stars have helped astronomers to work out their dimensions, structures, and shapes - even the existence of atmospheres and structures of exoplanets. Long before Columbus set out to reach the Far East by sailing West, the curved shadow of the Earth on the Moon during a lunar eclipse revealed that we inhabit a round world, a globe. More recently, comparisons of the sunlit and Earthlit parts of the Moon have been used to determine changes in the Earth's brightness as a way of monitoring possible effects in cloud coverage which may be related to global warming. Shadows were used by the Greek mathematician Eratosthenes to work out the first estimate of the circumference of the Earth, by Galileo to measure the heights of the lunar mountains and by eighteenth century astronomers to determine the scale of the Solar System itself. Some of the rarest and most wonderful shadows of all are those cast onto Earth by the lovely "Evening Star" Venus as it goes between the Earth and the Sun. These majestic transits of Venus occur at most two in a century; after the 2012 transit, there is not a chance to observe this phenomenon until 2117, while the more common sweep of a total solar eclipse creates one of the most dramatic and awe-inspiring events of nature. Though it may have once been a source of consternation or dread, solar eclipses now lead thousands of amateur astronomers and "eclipse-chasers" to travel the globe in order to experience the dramatic view under "totality." These phenomena are among the most spectacular available to observers and are given their full due in Westfall and Sheehan's comprehensive study.
Eclipse Chasers
Witnessing a total solar eclipse is a wondrous and unforgettable event! Eclipse Chasers is a guide to past and future Australian total solar eclipses, exploring historical and cultural knowledge, as well as featuring five upcoming eclipses that will be visible in Australia. The science of eclipses is explained, as well as how to prepare for an eclipse and view it safely. For upcoming eclipses the best locations to view each one are revealed, alongside tips for taking photographs. The book also reveals untold stories of how past Australian astronomers observed the total eclipses that have occurred since European settlement, and how these eclipses were celebrated in popular culture, poetry and art. It explores the great significance of solar eclipses for First Nations peoples, and their observations and cultural meanings. Eclipse Chasers showcases the drama and beauty of total solar eclipses and is essential for anyone fascinated by these amazing events. Features: An easy-to-understand guide to the science of a solar eclipse. Reveals inspiring stories about total eclipses in Australia, including stories of women and their often-unacknowledged involvement in science. Features First Nations observations and cultural meanings of total solar eclipses from a First Nations Elder and cultural astronomy expert. Includes locations and times to safely view a series of total solar eclipses coming up over the next two decades in Australia: April 2023; July 2028, Nov 2030, July 2037 and December 2038. Includes advice on total solar eclipse photography. The book includes information for teachers, and teacher notes will be available from the CSIRO Publishing website.
Gravity's Century : From Einstein's Eclipse to Images of Black Holes
A sweeping account of the century of experimentation that confirmed Einstein's general theory of relativity, bringing to life the science and scientists at the origins of relativity, the development of radio telescopes, the discovery of black holes and quasars, and the still unresolved place of gravity in quantum theory. Albert Einstein did nothing of note on May 29, 1919, yet that is when he became immortal. On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time. A century later, another group of astronomers is performing a similar experiment on a much larger scale. The Event Horizon Telescope, a globe-spanning array of radio dishes, is examining space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way. As Ron Cowen recounts, the foremost goal of the experiment is to determine whether Einstein was right on the details. Gravity lies at the heart of what we don't know about quantum mechanics, but tantalizing possibilities for deeper insight are offered by black holes. By observing starlight wrapping around Sagittarius A*, the telescope will not only provide the first direct view of an event horizon--a black hole's point of no return--but will also enable scientists to test Einstein's theory under the most extreme conditions. Gravity's Century shows how we got from the pivotal observations of the 1919 eclipse to the Event Horizon Telescope, and what is at stake today. Breaking down the physics in clear and approachable language, Cowen makes vivid how the quest to understand gravity is really the quest to comprehend the universe.
Totality : Eclipses of the Sun
A total eclipse of the Sun is the most awesome sight in the heavens. Totality: Eclipses of the Sun takes you to eclipses of the past, present, and future, and lets you see - and feel - why people travel to the ends of the Earth to observe them.Totality: Eclipses of the Sun is the best guide and reference book on solar eclipses ever written. It explains: how to observe them; how to photograph and videotape them; why they occur; their history and mythology; and future eclipses - when and where to see themTotality also tells the remarkable story of how eclipses shocked scientists, revealed the workings of the Sun, and made Einstein famous. And the book shares the experiences and advice of many veteran eclipse observers.Totality: Eclipses of the Sun is profusely illustrated with stunning photographs (many in color) and more than a hundred maps and diagrams. It can be read by lay people and astronomers with ease and enjoyment.
