Research Data Leeds lets visitors search, browse, and view recent additions to the university’s research data repository.
NASA/IPAC Extragalactic Database
NASA/IPAC Extragalactic Database provides astronomical object data and reports recent additions to its catalog.
About NASA/IPAC Extragalactic Database
The NASA/IPAC Extragalactic Database (NED) provides data on astronomical objects outside the Milky Way. It is funded by NASA and operated by the California Institute of Technology. The homepage reports recent catalog updates, including a September 2026 release that added 221K sources from the literature, with 157K cross-matched to existing NED objects and 63K new objects.
The homepage also lists recent additions, such as more than 8,000 Green Pea galaxies and candidates from SDSS DR18, 5K QSOs and galaxies from a strong gravitational lens search, and 91K spectroscopic redshifts from the VIPERS survey. Users who access NED programmatically should note that the legacy APIs are deprecated and cannot retrieve data ingested after January 2026. The homepage directs users to the new NED APIs for this data.
Key features

NASA/IPAC Extragalactic Database FAQ
Which API should I use to access recent NED data?
The homepage states that the legacy NED APIs are deprecated and cannot access data ingested after January 2026. It advises using the new NED APIs.
What did the September 2026 release add?
The release ingested 221K sources from the literature, including 157K cross-matches with existing NED objects and 63K new objects. It also increased the number of NED objects with redshifts by 89K.
What does NED ask authors to do before submitting a journal article?
The homepage asks authors to follow the Best Practices for Data Publication in the Astronomical Literature (Chen et al. 2022). This helps NED integrate data from their publications.
