This 6th edition of Tools of Radio Astronomy, the most used introductory text in radio astronomy, has been revised to reflect the current state of this important branch of astronomy. This includes the use of satellites, low radio frequencies, the millimeter/sub-mm universe, the Cosmic Microwave Background and the increased importance of mm/sub-mm dust emission.Several derivations and presentations of technical aspects of radio astronomy and receivers, such as receiver noise, the Hertz dipole and beam forming have been updated, expanded, re-worked or complemented by alternative derivations. These reflect advances in technology.The wider bandwidths of the Jansky-VLA and long wave arrays such as LOFAR and mm/sub-mm arrays such as ALMA required an expansion of the discussion of interferometers and aperture synthesis. Developments in data reduction algorithms have been included.As a result of the large amount of data collected in the past 20 years, the discussion of solar system radio astronomy, dust emission, and radio supernovae has been revisited.The chapters on spectral line emission have been updated to cover measurements of the neutral hydrogen radiation from the early universe as well as measurements with new facilities. Similarly the discussion of molecules in interstellar space has been expanded to include the molecular and dust emission from protostars and very cold regions.Several worked examples have been added in the areas of fundamental physics, such as pulsars.Both students and practicing astronomers will appreciate this new up-to-date edition of Tools of Radio Astronomy. The second edition of this popular text provides undergraduates with a quantitative yet accessible introduction to the physical principles underlying the collection and analysis of observational data in contemporary optical and infrared astronomy. The text clearly links recent developments in ground- and space-based telescopes, observatory and instrument design, adaptive optics, and detector technologies to the more modest telescopes and detectors that students may use themselves. Beginning with reviews of the most relevant physical concepts and an introduction to elementary statistics, students are given the firm theoretical foundation they need. New topics, including an expanded treatment of spectroscopy, Gaia, the Large Synoptic Survey Telescope, and photometry at large redshifts bring the text up to date. Historical development of topics and quotations emphasize that astronomy is both a scientific and a human endeavour, while extensive end-of-chapter exercises facilitate the students\' practical learning experience. Stargazing: Photographs of the Night Sky from the Archives of NASA is a photographic collection of the night sky\'s most extraordinary phenomena.These images from the archives of NASA reveal stunning photos of the cosmos, from radiant aurora borealis to awe-inspiring lunar eclipses.Complete with a preface by Bill Nye, this collection of photographs perfectly captures the wonder of looking up at the night sky.• Each breathtaking photo is paired with an informative caption about the scientific phenomena it reveals and the technology used to capture it• Beautiful on display on the coffee table• A go-to gift for both serious and casual stargazersThis collection of photographs illuminates the darkness of space in a whole new way.Blending art and science, the magnificent images of Stargazing captures the imagination of anyone interested in astronomy, travel, photography, and space exploration.• The only book from NASA that focuses solely on the night sky• A perfect gift for space lovers, stargazers, science geeks, scientists, parents, students, recent graduates, photographers and photography lovers, and NASA fans• Great for those who loved Earth and Space: Photographs from the Archives of NASA by Nirmala Nataraj, Infinite Wonder: An Astronaut\'s Photographs from a Year in Space by Scott Kelly, and The Hubble Cosmos: 25 Years of New Vistas in Space by David H. Devorkin and Robert W. Smith The ideal text for a one-semester course in radio astronomyEssential Radio Astronomy is the only textbook on the subject specifically designed for a one-semester introductory course for advanced undergraduates or graduate students in astronomy and astrophysics. It starts from first principles in order to fill gaps in students\' backgrounds, make teaching easier for professors who are not expert radio astronomers, and provide a useful reference to the essential equations used by practitioners.This unique textbook reflects the fact that students of multiwavelength astronomy typically can afford to spend only one semester studying the observational techniques particular to each wavelength band. Essential Radio Astronomy presents only the most crucial concepts--succinctly and accessibly. It covers the general principles behind radio telescopes, receivers, and digital backends without getting bogged down in engineering details. Emphasizing the physical processes in radio sources, the book\'s approach is shaped by the view that radio astrophysics owes more to thermodynamics than electromagnetism.Proven in the classroom and generously illustrated throughout, Essential Radio Astronomy is an invaluable resource for students and researchers alike.The only textbook specifically designed for a one-semester course in radio astronomyStarts from first principlesMakes teaching easier for astronomy professors who are not expert radio astronomersEmphasizes the physical processes in radio sourcesCovers the principles behind radio telescopes and receiversProvides the essential equations and fundamental constants used by practitionersSupplementary website includes lecture notes, problem sets, exams, and links to interactive demonstrationsAn online illustration package is available to professors How can there be one moon and many faces? One night it look full, the next it\'ll wane and the next it\'ll change yet again. This astronomy book for kids will explain the different phases of the moon and how each affects life on Earth.

This workbook, written by two master teachers, contains 36 field-tested activities, including nine new to the Second Edition, that span the introductory astronomy course and can be used in any size classroom. Each activity is now self-contained with an introduction that provides necessary background material for students. Activities are built around a concept that leads students from basic knowledge to a deeper understanding through guided interactions. The Second Edition is supported by Smartwork5, so instructors can easily assess student understanding. Written by two expert teachers and based on astronomy education research, this workbook guides students through concepts, promotes quantitative literacy, and increases student confidence in their understanding of how the universe works. A masterpiece of historical insight and scientific accuracy, this is the definitive work on Greek astronomy and the Copernican Revolution. Beginning with the ancient Egyptians, it ranges from the Pythagoreans and Plato to medieval European and Islamic cosmologies, concluding with detailed surveys of the works of Copernicus, Brahe, and Kepler.
