Sun, Earth and Sky - Lang, Kenneth R.

. .

Résumé :
Written in a light and friendly style, this lavishly illustrated book introduces the Sun and its physics, and describes all aspects of the Sun's interaction with us on Earth. It contains images never before seen in print. Breakthrough observations with the Sudbury Neutrino Observatory are also included which explain the new physics of ghostly neutrinos and solve the problematic mismatch between the predicted and observed amounts of solar neutrinos. This second edition updates the popular text by providing comprehensive accounts of the most recent discoveries made by five modern solar spacecraft during the past decade. It describes our recent understanding of how the Sun's outer atmosphere is heated to a million degrees, and just where the Sun's continuous winds come from. As humans we are more intimately linked with our life-sustaining Sun than with any other astronomical object, and the new edition therefore provides modern interpretations of ozone depletion and global warming....

Biographie:
Professor Lang has written several books about the Sun, as well as widely used reference works in astronomy and astrophysics. He has carried out radio observations of the active Sun with the Very Large Array in support of the SOHO spacecraft, teaches an extremely popular introductory course about the Sun to Tufts University students with non-scientific majors, and has served for two years as Visiting Senior Scientist in Solar Physics at NASA Headquarters....
