About the author
Mike Seeds was a professor of physics and astronomy at Franklin and Marshall College (F&M) in Lancaster, Pennsylvania, from 1970 until his retirement in 2001. In 1989 he received F&M College’s Lindback Award for Distinguished Teaching. Mike’s love for the history of astronomy led him to create upper-level courses on archeoastronomy and on the Copernican Revolution (“Changing Concepts of the Universe”). His research interests focused on variable stars and automation of astronomical telescopes. Mike is coauthor with Dana Backman of FOUNDATIONS OF ASTRONOMY, 14th Edition (2019); STARS AND GALXIES, 10th Edition (2019); THE SOLAR SYSTEM, 10th Edition (2019); and ASTRO, 3rd Edition (2018), all published by Cengage. He was senior consultant for creation of the 20-episode telecourse accompanying his book HORIZONS: EXPLORING THE UNIVERSE.Mike Seeds was a professor of physics and astronomy at Franklin and Marshall College (F&M) in Lancaster, Pennsylvania, from 1970 until his retirement in 2001.

He invented and taught a course titled “Life in the Universe” in F&M’s interdisciplinary foundations program. Dana has also taught introductory solar system astronomy at Santa Clara University, plus introductory courses on astronomy, astrobiology, cosmology and the science of climate change in Stanford University’s continuing studies program. His research interests focused on infrared observations of planetary system formation and evolution of the solar system’s Kuiper belt. Dana is employed by the SETI Institute in Mountain View, California, as lead for the Astronomy Activation Ambassadors teacher professional development program at NASA’s Ames Research Center.

His career began as an aerospace engineer who helped launch NASA's Space Shuttles. Eric transitioned to science, earning a Ph.D. in planetary science from the University of Arizona (Lunar & Planetary Lab), as part of the Mars Pathfinder mission. After Mars, he helped explore Saturn, discovering organic chemicals on Saturn's moons as member of the Cassini mission team at NASA Ames Research Center and the SETI Institute. Eric has taught astronomy, engineering, and physics courses at several colleges in the San Francisco Bay Area. He has traveled the world chasing solar eclipses and investigating nuclear sites including Hiroshima and Chernobyl. Eric has also authored Just Twelve Men, a history of the Moon landings, as well as a history of the Space Shuttle program.
