Dennis Mammana : ウィキペディア英語版 | Dennis Mammana Dennis Mammana (born September 5, 1951) is an astronomy writer, lecturer and sky photographer. His newspaper column "Stargazers" has run weekly since 1992, and his photos can be seen in national and international media. ==Early years== Born in Easton, Pennsylvania, Mammana's interest in "unseen worlds" began with a microscope, but his attention shifted skyward shortly after the launch of the first Earth-orbiting satellites Sputnik I and Echo I in the late 1950s. By the mid-1960s, he began regularly observing and photographing the sky, and built a basement darkroom where he developed and printed his own sky photographs. His first published photo was of the total lunar eclipse of April 12, 1968, which appeared in ''The Express-Times'' the following day.
