NEOWISE 2020 Data Release Now Available

The Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) and IPAC at the California Institute of Technology announce the NEOWISE 2020 data release.

The NEOWISE 2020 data release adds to the public archive all data acquired during the sixth year of the operations of the NEOWISE Reactivation mission (Mainzer et al. 2014, Astrophysical Journal, 792, 30). The combined archive of the first six years of NEOWISE data includes approximately 15.3 million sets of calibrated 3.4- and 4.6-micron images and a database of over 114 billion source detections extracted from those images. 

NEOWISE scanned the sky nearly twelve complete times during the first six years of survey operations, with approximately six months between survey passes.  With twelve or more independent 3.4- and 4.6-micron exposures made on each point of the sky during each survey epoch, the NEOWISE archive is a time-domain resource for extracting multiple, independent thermal flux and position measurements of solar system small bodies, as well as galactic and extragalactic sources.

A quick guide to the NEOWISE data release, data-access instructions, and supporting documentation is available on the Release introduction page. Access to the NEOWISE data products is available via the online and API services of the NASA/IPAC Infrared Science Archive.

NEOWISE is a joint project of the Jet Propulsion Laboratory/California Institute of Technology and the University of Arizona. NEOWISE is funded by the National Aeronautics and Space Administration Planetary Science Division.
