Espenak earned a bachelor's degree in physics from Wagner College, Staten Island, where he worked in the planetarium. His master's degree is from the University of Toledo, based on studies he did at Kitt Peak Observatory of eruptive and flare stars among red dwarfs.
Espenak is the author of several canonical works on eclipse predictions, such as the Fifty Year Canon of Solar Eclipses: 1986–2035 and Fifty Year Canon of Lunar Eclipses: 1986–2035. He also publishes eclipse bulletins for NASA. He is co-author with Jean Meeus of Five Millennium Canon of Solar Eclipses, NASA Goddard Space Flight Center, October 2006.
