    Astronomers are often asked to determine the time, date, and plausibility of events based on the appearance of the sky. Texas researchers have been investigating famous historical events, art, and literature by studying the astronomical configurations they can deduce were in force at the time. For example: Ansel Adams took the photograph entitled "Autumn Moon, the High Sierra from Glacier Point" some time in 1948 ? or was it another year, as some have argued? Donald Olson and Russell Doescher say no! It was actually Sept. 15, 1948, at 7:03 p.m. Pacific Daylight Time. This scene repeated itself this year at nearly the same time on September 15. An added bonus of the astronomers' investigation: a discovery of a color version Adams took while testing Kodak film.
