NASA Retires Asteroid-Hunting Telescope NASA’s NEOWISE telescope has searched for asteroids, brown dwarfs and luminous galaxies. The spacecraft will soon burn up in Earth’s atmosphere

There is now a new version of the WISE and ZTF image services! These two tools are now using the latest-and-greatest version of Firefly, the software that provides the look-and-feel of the plots/tables/images in these tools. The online help has been updated, but the movies are still to come!

Two new catalogs are now available: the Gaia-unWISE Quasar Catalog (Quaia), and the SOFIA/FORCAST Galactic Center Catalog (SFGC). Access them via the Catalog Search Tool https://irsatest.ipac.caltech.edu/applications/Gator/

This result uses data from Planck and Herschel, whose affiliated NASA science centers were based here at IPAC and whose data can still be accessed via IRSA.

Dark Matter Flies Ahead of Normal Matter in Mega Galaxy Cluster Collision The research provides a unique look at how this matter decoupling proceeds.

Start your summer with a splash by diving into a simulated universe! 💦

Scientists used supercomputers to create about 4 million synthetic images depicting the cosmos as the Roman and Rubin Observatory will see it. Researchers will use the simulated images to prep for future real data that will help them unravel the biggest mysteries in cosmology.

ZTF PUBLIC DATA RELEASE 21: Now available

The Zwicky Transient Facility (ZTF) and IPAC at the California Institute of Technology announce the twenty-first ZTF Public Data Release. ZTF is an optical time-domain survey covering the northern sky visible from Palomar Observatory since 17 March 2018. This release adds 4 months of observations to the twentieth data release, up to 29 February 2024 for the public portion of the survey, and private survey time prior to 31 October 2022. The private surveys include observational programs awarded by Caltech or performed by the ZTF collaboration.

The products include 56.3 million single-exposure images, 176 thousand co-added images, accompanying source catalog files containing 860 billion source detections extracted from those images, and 4.89 billion light curves constructed from the single-exposure extractions.

A guide to ZTF Data Release 21, with data access instructions and supporting documentation, is available at https://irsa.ipac.caltech.edu/data/ZTF/docs/releases/ztf_release_notes_latest

Access to the data products is available via the on-line and API services of the NASA/IPAC Infrared Science Archive (IRSA) at https://irsa.ipac.caltech.edu/Missions/ztf.html

Note: transient alerts extracted from difference-images commenced public distribution on June 4, 2018. These alerts continue to be generated and distributed to brokers as the public survey proceeds. For further details and alert archive see https://ztf.uw.edu/alerts/public

ZTF is supported by the National Science Foundation under Grants No. AST-1440341 and AST-2034437 and a collaboration including current partners Caltech, IPAC, the Oskar Klein Center at Stockholm University, the University of Maryland, University of California Berkeley, the University of Wisconsin at Milwaukee, University of Warwick, Ruhr University, Cornell University, Northwestern University and Drexel University. Operations are conducted by COO, IPAC, and UW.

IPAC Executive Director George Helou Stepping Down at the End of 2024

After more than four decades of dedicated service to IPAC, George Helou has announced he is stepping down as IPAC Executive Director at the end of the year.

Noting that IPAC is involved with a mission launch almost every year for the next few years, Helou said this was a good time to hand over the reins to a successor. “The organization is healthy. The future is as promising as it has ever been.” he said.

Helou will transition into his role as a Research Professor of Physics at Caltech, a position he has maintained since 1998.
