Editorial Reviews

From Publishers Weekly

Why does the sun seem to elongate before it sets below the horizon? Why do some stars look blue and others red? Yale University astronomer Upgren (Night Has a Thousand Eyes) takes readers on a tour of the night sky and answers these and other questions in this winsome collection of essays. He tells us that in 50,000 years the stars in the Big Dipper will no longer be in a recognizable asterism; explains why stars seem first to move in one direction, then in another; and addresses the problem of urban light pollution. Though science buffs may already be familiar with much of this material, novices and younger readers should find much to inspire and inform them.

From Library Journal

Upgren, a professional astronomer associated with two universities (Yale and Wesleyan), has two previous popular science works to his credit (Night Has a Thousand Eyes and Weather: How It Works and Why It Matters). This collection focuses on astronomy, and many of the essays are tied together by the subject of light pollution. Upgren, a longtime crusader against light pollution, argues that excessive and poorly directed lighting has increasingly interfered with ground-based astronomy and adversely affected a number of wildlife species. He explains how reasonable lighting controls can help astronomy and the environment without harming human public safety or reasonable advertising needs. Other brief essays discuss various astronomical topics at a lay reader's level. In general, Upgren's book makes for good reading and could be used as a supplemental text for college-level introductory courses. However, it could have been improved by tighter editing to eliminate repetitious sections. Also, a few areas where the line of argument is not pursued very vigorously could have been either strengthened or eliminated. For general science collections. Jack W. Weigel, Ann Arbor, MI
