Jerry T. Bonnell is an American astrophysicist associated with NASA Goddard Space Flight Center and the University of Maryland. He is especially known as the co-creator and longtime editor of Astronomy Picture of the Day (APOD), the hugely popular project he launched with Robert J. Nemiroff in 1995.
Alongside his research background, Bonnell has written and co-written books that bring astronomy to a broad audience, including The Universe: 365 Days and Astronomy: 365 Days. His work is known for pairing remarkable space imagery with short, approachable explanations that make complex ideas feel accessible.
A brief biographical sketch published through APOD says he earned his Ph.D. from the University of Maryland in 1987. Across his scientific and public-facing work, he stands out as a writer who helps readers slow down, look up, and enjoy the universe with curiosity rather than intimidation.
