NASA’s Astronomy Picture of the Day website, known as APOD, serves a single daily image of the universe selected by Robert Nemiroff and Jerry Bonnell, geopop.it reported. The project provides short professional explanations for every feature published. The project has published for more than thirty-one years across over 11,000 days, featuring not only photographs but also videos, simulations, artistic representations, or visualizations of astronomical data, atmospheric phenomena, and space explorations, such as an October APOD featuring the September full moon, known as the harvest moon, with Mount Etna erupting in the background, captured by Italian Dario Giannobile.
The Launch of APOD in 1995
Robert Nemiroff and Jerry Bonnell launched the website on June 16, 1995, during the early days of web browsers and Mosaic, geopop.it reported, after discussing during a summer what kind of project they could build given their specialization and how they might answer astronomy questions. Their first day online recorded 14 page views before the project grew into a permanent daily fixture of astronomical outreach, created originally to valorize the vast NASA image archive gathered among expeditions, probes, and telescopes before opening submissions to anyone.
New Astrophysicists Join the Image Curation Team
The platform receives roughly 30 image submissions every day from amateurs, observatories, and international contributors, geopop.it reported. Nemiroff has served as a professor at Michigan Technological University since 1996. To help coordinate and curate the project alongside Nemiroff and Bonnell, Cecilia Chirenti and Keighley Rockcliffe joined the team at the beginning of 2026, bringing new energies and viewpoints as both hold PhDs in Astrophysics, making them capable of understanding why an image matters and explaining it. The main page also features a Random Footer Generator that proposes a random image from the archive, while users can search images from the launch through January 31, 1996, in a preserving archive page and subsequent ones via a calendar.
Mirror Sites Maintain Publication During Government Shutdowns
United States federal government shutdowns occasionally disrupted publishing operations, geopop.it reported, because when the US government and related websites underwent shutdowns halting online content publication, the creators could not ignore it or work voluntarily during funding lapses due to perception and rules. To maintain continuous daily publication during those funding lapses, the team relied on mirror websites hosted elsewhere, such as the University College of London. These temporary mirror locations served as the primary access points until standard federal operations resumed.
Frequently Asked Questions About APOD
How many images does APOD publish each day?
The site publishes exactly one image or visual media piece per day, selected from about 30 daily submissions received from global contributors, geopop.it reported.
