What Matters More Than Metrics? A&A Reflects with its Community

Details: Published on 24 September 2025

Paris, France, 24 September 2025. In the 2024 edition of the Journal Citation Reports™ released by Clarivate in June, Astronomy & Astrophysics (A&A) received an Impact Factor of 5.8, placing it firmly at the head of the leading journals for original research in astronomy and astrophysics. We were pleased with this result, and are even more pleased to report that, after one of our community members identified missing citations from the highly-cited Gaia Data Release 3 article and raised the issue with the Editors, Clarivate reviewed the record at the request of the publisher, EDP Sciences, and corrected the calculation. A&A’s Impact Factor is now 6.1, and this corrected figure will be formally reflected in the October reload of the JCR.
