Boken NORRSKEN ger en fascinerande presentation från gamla tiders myter till dagens moderna polarskensforskning.
|This is the first serious book about aurora written for practical but non-professional observers. It provides a concise accessible description of the various auroral forms and how to record them, illustrated with color images of recent displays.
|Aurorae are bands of colored light that appear when electronically charged particles from the sun penetrate the Earth's upper atmosphere. This book examines the underlying causes and occurrence of the aurora. It contains illustrated descriptions of auroral forms and advice on how to observe and photograph the aurora.
|I Norrsken, budbärare från rymden beskriver Ingrid Sandahl bl.a. vad norrsken är, hur vår kunskap om fenomenet vuxit fram och om hur norrskensforskningen bedrivs. Bruket av sondraketer och satelliter har inneburit en revolution inom rymdforskningen och en helt ny bild av solsystemets upp byggnad och funktion håller på att växa fram.
Ingrid Sandahl är docent i rymdfysik och verksam vid Institutet för rymdfysik i Kiruna
|Authors Carlowicz and Lopez explain what space weather really means to us down here, and what it may mean for future explorations and colonization of distant worlds. By translating the findings of NASA and other top scientists into fascinating and accessible descriptions of the latest discoveries, we are privy to some of the most closely held secrets that the solar terrestrial system has to offer.
|Unlike other astrophotography books, this one focuses specifically on DSLR cameras, not astronomical CCDs, non-DSLR digital cameras, or film. This guide is ideal for astrophotographers who wish to develop their skills using DSLR cameras and as a friendly introduction to amateur astronomers or photographers curious about photographing the night sky.
|This book is a 400+ page comprehensive, nuts-and-bolts introduction to digital astro-imaging written by Robert Reeves, an accomplished author and film imager with nearly 50 years of experience who has enthusiastically made the transition to digital imaging. Robert describes how the family digital camera you probably already own can be used to take spectacular pictures of the night sky. T
|Provides a complete guide to taking pictures of stars, galaxies, the Moon, the Sun, comets, meteors and eclipses, using equipment and materials available to the hobbyist.
|Author and world-renowned astrophotographer Thierry Legault teaches the art and techniques of astrophotography: from simple camera-on-tripod night-scene imaging of constellations, star trails, eclipses, artificial satellites, and polar auroras to more intensive astrophotography using specialized equipment for lunar, planetary, solar, and deep-sky imaging. Legault shares advice on equipment and guides you through techniques to capture and process your images to achieve spectacular results.
|That rare mastery is on full display in this beautiful volume of space photography from thirty of the most accomplished astrophotographers in the world, both professional and amateur. Galaxies, star clusters, nebulae, and other deep-sky treasures fill the pages.
|This book introduces halos and tries to convey some of their beauty. It tells much of what is known about them: how they arise, how so many are possible, and why some are rare, while others occur every few days or so. No such insights, of course, are necessary for the enjoyment of a halo display; indeed, an elaborate display is one of Nature's wonders. Nevertheless, understanding can add to enjoyment, especially since the makings of a great display turn out to be as remarkable as the display itself.
|Atmospheric halos are visible phenomena of much beauty and fascination. From our earliest known records, dating from the Sumerian-Babylonian culture of 4-5,000 years ago, to modern researchers, halos have kept us looking skyward. Caused by light refracted through ice crystals floating in the atmosphere, they can appear at nearly any time and place. What do the ice crystals look like, especially those that make the exotic "odd radius" halos? What is the value of the elusive angle x, so critical to determining the shapes of these crystals?
