International Ultraviolet Explorer was considered the most successful astronomical satellite ever. The human eye can perceive light with wavelengths between roughly 350 (violet) and 700 (red) nanometres. Ultraviolet light has wavelengths between roughly 10 nm and 350 nm. UV light can be harmful to human beings, and is strongly absorbed by the ozone layer. This makes it impossible to observe UV emission from astronomical objects from the ground. Many types of object emit copious quantities of UV radiation, though: the hottest and most massive stars in the universe can have surface temperatures high enough that the vast majority of their light is emitted
Out of Gas: The End of the Age of Oil a simple observation about natural resources. He described "Out of Gas: The End of the Age of Oil" in "The New York Times" as "a book that is more powerful for being brief -- takes a detour to explain some of the basics of energy budgets, thermodynamics and entropy, and it does so with the clarity and gentle touch of a master teacher". Raeburn concluded about Goodstein's book: "Publishers Weekly" commented on the book: Brian Braiker described the book in "Newsweek" as an "important one" where Goodstein gives the explanation of the science behind his prediction.
