Summary

Story summary

NASA's SPHEREx mapped water ice in the Cygnus X region, about 4,500 light-years away.
The ice is shielded by dust particles.
Dense ice regions align with dust lanes, shielding them from ultraviolet radiation of newborn stars.
SPHEREx launched in March 2025 and surveys the entire sky in 102 wavelengths.
The findings, published in The Astrophysical Journal, could advance understanding of the origins of water and life.
