Visual Lunar and Planetary Astronomy by Paul G. Abel Pdf
With the advent of CCDs and webcams, the focus of amateur astronomy has to some extent shifted from science to art. Visual work in astronomy has a rich history. Today, imaging is now more prominent. However there is still much for the visual amateur astronomer to do, and visual work is still a valid component of amateur astronomy. Paul Abel has been addressing this issue by promoting visual astronomy wherever possible – at talks to astronomical societies, in articles for popular science magazines, and on BBC TV’s The Sky at Night. Visual Lunar and Planetary Astronomy is a comprehensive modern treatment of visual lunar and planetary astronomy, showing that even in the age of space telescopes and interplanetary probes it is still possible to contribute scientifically with no more than a moderately-priced commercially made astronomical telescope. It is believed that imaging and photography is somehow more objective and more accurate than the eye, and this has led to a peculiar “crisis of faith” in the human visual system and its amazing processing power. But by analyzing observations from the past, we can see how accurate visual astronomy really is! Measuring the rotational period of Mars and making accurate lunar charts for American astronauts were all done by eye. The book includes sections on how the human visual system works, how to view an object through an eyepiece, and how to record observations and keep a scientific notebook. The book also looks at how to make an astronomical, rather than an artistic, drawing. Finally, everything here will also be of interest to those imagers who wish to make their images more scientifically applicable by combining the methods and practices of visual astronomy with imaging.
Modern comprehensive review of the formation, astronomy, and structure of Saturn and its ring system, and observing techniques for amateurs Very latest detailed theories and physical descriptions How to observe and image the Saturn, its moon and ring, using a variety of telescope apertures and magnifications
First observed by Galileo, Saturn lies in the distant reaches of the solar system; it is the sixth planet, a gaseous giant between Jupiter and Uranus. It takes its name from the mythological father of Jupiter and Roman god of agriculture. Because of the famous circle of rings Saturn is one of the most well-regarded occupants of the galaxy. Despite their continuous appearance from Earth, the rings are actually space dust and debris trapped by Saturn's gravitational pull, a fact garnered from several satellite passes and telescope observations. The origin of Saturn's rings, however, remains a mystery. Apart from the rings, we also are aware of its moon system, with the most intriguing planetoid called Titan, itself having been the subject of science fiction speculation as a home to life. Saturn has been visited by Pioneer 11 and the two Voyager probes, with Cassini slated to arrive in 2004. Our study of this most intriguing planet will continue into the foreseeable future, with the hopes of resolving the mysteries it hides. This book provides a thorough and interesting overview of Saturn, from its initial observation centuries ago to the contemporary satellite fly-bys. Anyone captivated by the mysteries of space and the wonders of Saturn needs to understand the background covered here. After the overview is a substantial and carefully selected set of abstracts of literature pertaining to Saturn, with easy access then given through author, title, and subject indexes.
The Saturn System Through The Eyes Of Cassini by Nasa Pdf
The Saturn System Through The Eyes Of Cassini is printed in full-color on 70-pound paper. The Cassini-Huygens mission has revolutionized our knowledge of the Saturn system and revealed surprising places in the solar system where life could potentially gain a foothold--bodies we call ocean worlds. Since its arrival in 2004, Cassini-Huygens has been nothing short of a discovery machine, captivating us with data and images never before obtained with such detail and clarity. Cassini taught us that Saturn is a far cry from a tranquil lone planet with delicate rings. Now, we know more about Saturn's chaotic, active, and powerful rings, and the storms that rage beneath. Images and data from Saturn's moons Titan and Enceladus hint at the possibility of life never before suspected. The rings of Saturn, its moons, and the planet itself offer irresistible and inexhaustible subjects for intense study. As the Cassini mission comes to a dramatic end with a fateful plunge into Saturn on Sept. 15, 2017, scientists are already dreaming of going back for further study.
In the summer of 2004, the Cassini-Huygens space probe began an extensive study of Saturn. This engaging text incorporates some of the most recent discoveries about Saturn, its satellites, and its famous planetary rings. Full-color images accompany a detailed exploration of the sixth planets climate, composition, and orbit.
"Discusses the planet Saturn, including observations by ancient cultures, current knowledge of Saturn, and plans for future scientific research and space exploration"--
Saturn is the showpiece planet of our solar system. It may not be the largest, nor the smallest, nor even the only planet with rings. But it is among the most stunning objects in the sky and is always breathtaking when seen in a telescope. This is a beautifully illustrated, authoritative overview of the entire history of humankind’s fascination with the ringed planet, from the first low-resolution views by Galileo, Huygens, and other early observers with telescopes to the most recent discoveries by the spacecraft Cassini, which studied the planet at close range between 2004 and 2017. Saturn describes the planet from inside out, detailing the complicated system of rings and their interaction with Saturn’s bevy of satellites, and it considers how Saturn formed and the role it played in the early history of the solar system. Featuring the latest research and a spectacular array of images, this book will appeal to anyone who has ever gazed with wonder upon the sixth planet from the sun.
