Rick earned his BA in physics at Rice University and his MA and PhD in astronomy at Harvard University; he has done research on the aurora borealis, asteroids, planetary nebulae, active galaxies, and the center of the Milky Way. He is a co-creator of the Galileoscope educational telescope kit, a Cornerstone Project of the International Year of Astronomy 2009 and the International Year of Light 2015. Rick is an elected Fellow of the American Association for the Advancement of Science (AAAS). The International Astronomical Union (IAU), which he serves as Vice-President of Commission C2, Communicating Astronomy with the Public, has named asteroid 9983 Rickfienberg in his honor.
Though trained as a professional astronomer, Rick remains an amateur at heart, observing the sky and taking astrophotos from his private observatory in central New Hampshire. An inveterate traveler, often in pursuit of total solar eclipses, Rick has visited all seven continents and the North and South Poles.
