Mars and How to Observe It

Bol

This book details how amateur and practical astronomers can successfully observe Mars. It uses recent imagery and data to present an up-to-date guide to Mars' geological history and contains a unique set of maps that cover the entire Martian surface. Mars has long been a favorite subject for astronomers, both amateur and professional. Known as the Red Planet because of its distinct color, it shines brightly in the skies when it is closest to the Earth every two years. Exciting to view through a telescope, this most Earth-like of planets transforms into a real world showing phases, brilliant polar ice caps, seasonal changes in its dusty desert markings, and atmospheric phenomena. Mars and How to Observe It takes readers on a planet-wide tour of the Red Planet and explains how a variety of dynamic forces has shaped it through the ages. This book explains how amateur astronomers can view Mars successfully to create accurate observational drawings and secure high-resolution CCD images of the planet. Peter Grego is an accomplished author, an experienced amateur astronomer who has been actively observing Mars for over 30 years. Using the latest imagery and data from Mars probes and rovers, Mars and How to Observe It presents an up-to-date guide on our current understanding of the Red Planet and how the amateur astronomer can become familiar with this fascinating world. Mars, popularly known as the Red Planet because of its distinct color, is visible with the naked eye and is one of very few planets in the Solar System in which it is possible to see weather phenomena and surface features and thus is a favorite for amateur and practical astronomers. Commercially made telescopes can reveal its dusty surface markings, brilliant polar ice caps, and atmospheric phenomena. Many of Mars's features appear to change shape and intensity with the seasons: its polar caps grow and shrink cyclically, clouds billow above the Martian surface, and sometimes great dust storms obscure vast sections of the planet. The first part of Mars and How to Observe It sets out our current knowledge of Mars as a planet - its orbit, physical characteristics, evolution over time, and current geology. A planet-wide tour of Mars's topography is featured, along with clearly labeled maps and close-up images of a variety of features. The second part of the book explains how amateur and practical astronomers can observe Mars successfully. Many aspects are considered in depth, including preparing to observe, calculating phase and tilt, and making observational sketches and drawings. There are also plenty of details about how best to make high-resolution CCD images. Since Mars changes in its apparent size in the sky according to its position in relation to Earth, it is best observed during its closest approaches. Future apparitions (appearances of the Red Planet) are therefore featured.
