'Interstellar Glaciers': NASA’s SPHEREx Maps Vast Galactic Ice Regions
News Release
April 15th, 2026
NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) mission has mapped interstellar ice at an unprecedented scale. Covering regions in our Milky Way galaxy more than 600 light-years across, the ice was found inside giant molecular clouds — vast regions of gas and dust where dense clumps of matter collapse under gravity, giving birth to stars. A study describing these findings published Wednesday in The Astrophysical Journal.

ENSCI received NASA award “For group achievement in successful delivery of calibration and software updates for
processing Euclid-NISP instrument data during the first six months of the Euclid mission.”
Our Mission
IPAC at Caltech partners with NASA, NSF, JPL and the world-wide research community to advance exploration of our Universe. Beginning with the IRAS mission in 1983 and spanning through 2MASS, Spitzer, Herschel, Planck, WISE/NEOWISE and Euclid in recent years, we have enabled transformative research of the entire sky. We provide science operations, user support, archives and data services, and scientific vision to maximize discovery with observatories both in space and on the ground. In 2025 SPHEREx launched. Next up, Roman, NEO Surveyor, and UVEX are all preparing to launch in the years ahead. We share these advances and discoveries with everyone through education outreach programs and award-winning communications. Our community of active researchers is dedicated and essential to fulfilling this mission.

Science at IPAC
Our community of active researchers is key to the strategic development and execution of all programs supported by IPAC. IPAC scientific staff are engaged in research spanning a broad range of fields in astrophysics and planetary sciences. Areas of special focus include exoplanets; dark energy and cosmology; star formation and galaxy evolution; asteroids and the solar system; and the area in which IPAC has provided leadership for over three decades -- exploration of the infrared and sub-mm universe.
