The invisible universe

de David Malin

"Using some of the most powerful Earth-based telescopes, astronomer and photographer Malin has spent over twenty years painstakingly capturing the previously undetected colors and forms of gas, dust, and light in the farthest reaches of space.The unusual photographic process that Malin devised requires three different exposures, which may be taken years apart, in order to produce each picture.". "The informative and entertaining text combines the science, poetry, and lore behind these glorious objects. It outlines the story of their discovery and observation along with vivid descriptions of the life cycles of stars, setting them in the context of their distance, age, and environment."--BOOK JACKET.
