Open Journal of Astrophysics (OJAp) is a peer-reviewed scientific journal in astronomy and astrophysics. It publishes original research in the form of scientific papers. OJAp is a relatively new academic journal in astrophysics. Over the past few years, it has rapidly gained traction, after several other formerly free-to-publish journals in astronomy and astrophysics changed to have high fees. A founding motivation for OJAp was to avoid unnecessarily costly subscriptions to academic journals for universities, and article processing fees for authors. The typical time from submission to acceptance is 2–3 months. In 2023 the journal published 50 articles, increasing to 121 in 2024, while in 2025 the journal published 214 articles, according to Harvard ADS. This makes it roughly ten times smaller than the most known and used astronomy journals, such as MNRAS. Professors from the top international astronomy and astrophysics research institutions, including Princeton, Caltech, MIT, and Harvard now regularly publish in OJAp.
