MammanaAstronomy Writer, Lecturer & Sky Photographer

For nearly four decades, Dennis Mammana has shared the wonder and mystery of the cosmos with audiences around the world.

He received his B.A. in Physics & Astronomy from Otterbein College and his M.S. in Astronomy from Vanderbilt University, and was awarded a coveted one-year internship at the world-famous Strasenburgh Planetarium in Rochester, N.Y. He has held positions at the Smithsonian’s National Air & Space Museum, the University of Arizona and San Diego's Reuben H. Fleet Science Center.

Mammana is the author of six books on astronomy, hundreds of popular magazine, encyclopedia and web articles and, since 1992, has written Stargazers, the only nationally syndicated weekly newspaper column on astronomy. His award-winning night sky photographs have been seen in print and electronic media, and have been shown in exhibitions around the world. He is an invited member of TWAN (The World at Night), a global team of the most highly acclaimed sky photographers on the planet. And as a dynamic public speaker, Mammana has entertained and informed audiences on six continents—at resorts, on cruise ships, as an after-dinner speaker, and on both radio and television.

Mammana lives and works in Southern California’s Anza-Borrego Desert where he writes about—and photographs—the spectacular night sky. You can enjoy his work online at his website and on his Facebook page.
