NEOWISE 2019 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 2019 data release.

The NEOWISE 2019 data release adds to the public archive all data acquired during the fifth year of the operations of the NEOWISE Reactivation mission (Mainzer et al. 2014, Astrophysical Journal, 792, 30). The combined archive of the first five years of NEOWISE data includes approximately 12.8 million sets of calibrated 3.4- and 4.6-micron images and a database of more than 95 billion source detections extracted from those images. 

NEOWISE scanned the sky nearly 10 complete times during the first five years of surveying, with approximately six months between each survey pass. With 12 or more independent 3.4- and 4.6-micron exposures made on each point of the sky during each survey epoch, the NEOWISE data 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 index page. Access to the NEOWISE data products is available via the online and API services of the NASA/IPAC Infrared Science Archive (IRSA).

NEOWISE is a project of the Jet Propulsion Laboratory/California Institute of Technology and is funded by the NASA Planetary Science Division.
