For nearly five decades, Dennis Mammana has delivered the wonder and mystery of the cosmos to audiences around the world. Dennis grew up in Easton, PA, a historic city at the confluence of the Lehigh and Delaware Rivers, and his fascination with the heavens began with the launching of the first Earth-orbiting satellites in the late-1950s. With a degree in physics and astronomy from Otterbein College (now Otterbein University), he was one of only two astronomy graduate students admitted to Vanderbilt University in 1973. His research there included using the 24-inch (0.61-meter) telescope at the Arthur J. Dyer Observatory to conduct a year-long photometric study of optical variability in the nuclei of three distant Seyfert Galaxies. After completing graduate school, Mammana was selected from a field of 55 applicants for a coveted internship at the world-famous Strasenburgh Planetarium, and has since held positions at the Smithsonian Institution's National Air & Space Museum, the University of Arizona, and San Diego's Reuben H. Fleet Science Center. His original planetarium programs have been enjoyed from New York to Calcutta to Brisbane, and in their production he has directed such luminaries as actors Burgess Meredith and Patrick Stewart, and has collaborated with science fiction icon Arthur C. Clarke. Mammana is the author of six books on popular astronomy―including the first-ever book about the search for extra-solar planetary systems―as well as hundreds of popular magazine and encyclopedia articles, scripts and blogs. Since 1992, he written Stargazers , the only syndicated newspaper column about astronomy, now in its 27th consecutive year. In 1985 he was a candidate for NASA’s Journalist in Space program, before the Space Shuttle was grounded after the Challenger accident. As a noted and accomplished night sky photographer, his stunning celestial imagery has earned him a invited membership in TWAN (The World at Night). He is one of only six representing the U.S. in this elite international team of the most experienced and highly-acclaimed night sky photographers on the planet. April 2018 marked the 50th anniversary of his first published photo. A dynamic public speaker, Mammana has entertained, inspired and informed audiences at resorts, museums, corporate events and with cruise lines, including Sitmar, Radisson Seven Seas, Hurtigruten, Royal Caribbean, and more; in early 2019 he returned for his 23rd year as an invited enrichment lecturer with Crystal Cruises , the world’s most awarded luxury cruise line. Since the mid-1980s, Mammana has led many public aurora borealis-, comet- and total solar eclipse-observing expeditions on six continents and, since 1994, has been a popular astronomical and photographic lecturer on tours offered by MWT Associates . He has 17 total solar eclipses under his belt, and is excitedly awaiting number 18 in July of 2019. He has hosted a weekly astronomy news segment on San Diego's KUSI-TV, and co-hosted "Quarks to Quasars" on UCSD-TV as well as the Emmy Award-winning documentary "San Diego Night Sky" with KPBS-TV. He is the recipient of the Robert Burnham Jr., Award for Exceptional Service in Astronomy from the Astronomical League and the Special Achievement Award from Otterbein College. In 2009 his astronomical contributions to the community of Borrego Springs (the only International Dark Sky Community in California) were honored as he was named Grand Marshal of the 44th Annual Borrego Days Desert Festival. Mammana now works as an astronomy writer, lecturer and photographer under the clear, dark skies of Southern California's Anza- Borrego Desert.
