The Astronomical Journal (AJ) is a peer‑reviewed scientific journal that publishes original research articles in the fields of astronomy and astrophysics. It is one of the principal journals of the American Astronomical Society (AAS) and is published by IOP Publishing on behalf of the AAS.
History
The journal was established in 1849 by astronomer Benjamin A. Gould, originally under the title Astronomical Journal. It is the second-oldest continuously published astronomical journal in the United States, following the Astronomical Society of the Pacific (ASP) publications. Over its more than 170‑year history, the journal has undergone several changes in editorial policy, format, and publishing frequency, adapting to evolving research practices in the astronomical community.
Scope and Content
The Astronomical Journal focuses on observational and theoretical studies of all aspects of astronomy and astrophysics, including but not limited to:
- Stellar and planetary systems
- Galactic and extragalactic astronomy
- Cosmology and large‑scale structure
- Instrumentation, techniques, and data analysis methods
Articles are expected to present significant, original contributions and are subjected to a rigorous double‑blind peer‑review process.

Access and Indexing
The journal is available both in print and electronically. Its contents are indexed in major scientific databases, including the Science Citation Index Expanded, Scopus, and the Astrophysics Data System (ADS). Open‑access options are provided under a hybrid model, allowing authors to choose between traditional subscription‑based publication and author‑paid open‑access.
Relation to Other AAS Journals
The Astronomical Journal is one of three flagship journals of the American Astronomical Society, the others being The Astrophysical Journal (ApJ) and The Astrophysical Journal Supplement Series (ApJS). While the AJ traditionally emphasizes observational data and detailed analyses of specific astronomical objects, the ApJ covers a broader range of theoretical and observational research, and ApJS publishes extensive data sets and methodological papers.
Notable Contributions
Over its long history, the AJ has published seminal papers that have contributed to major advances in astronomy, such as early measurements of stellar parallaxes, the discovery of exoplanetary systems, and detailed surveys of galaxy morphology. Specific landmark articles are documented in the journal’s archival records and citation databases.
Affiliations and Governance
The journal operates under the governance framework of the American Astronomical Society, with editorial decisions overseen by an editorial board composed of active researchers representing diverse subfields of astronomy. The AAS provides policy guidance on issues such as research integrity, data availability, and diversity in publishing.
