IRSA has released a new SPHEREx Mosaic Tool for creating spectral cubes from SPHEREx Spectral Images. The tool lets users specify the output mosaic geometry, pixel scale, and wavelength range, producing a FITS cube with up to 102 wavelength planes corresponding to the standard SPHEREx channels.

Users can explore the resulting cube using standard IRSA visualization and extraction tools. Drill extraction provides a fast way to look through the cube at a selected position and generate a spectrum-like quick-look product. For science-quality spectra derived from SPHEREx Spectral Images, users should use the SPHEREx Spectrophotometry Tool.

The SPHEREx List of Ice Sources catalog is now available in IRSA's Catalog Search tool.

We invite you to join a hands-on workshop during the 248th Meeting of the American Astronomical Society (June 14-18, 2026) in Pasadena, California focused on the new cloud-based NASA Astrophysics Science Platform known as the Fornax Science Console. Please remember to sign up in advance—spots are limited! Regular registration for AAS closes May 21st, 2026.

Workshop Name: An Introduction to Fornax: Scalable Data and Compute for Scientific Analysis

Workshop Date/Time: June 14, 2026 (2:00 PM – 4:00 PM PST)

Location: AAS, Pasadena, USA

This session will introduce participants to Fornax, now in beta, and demonstrate how to access NASA astrophysics data sets in the cloud and analyze them using scalable computing resources. Through guided exercises and live demonstrations, attendees will explore practical workflows such as cross-matching large catalogs using HATS/Parquet formats and working directly with cloud-hosted data using familiar tools.
