NASA's SPHEREx Mission Maps Water Ice in Cygnus X, Revealing Star Birth Secrets
NASA's SPHEREx mission has successfully mapped water ice and polycyclic aromatic hydrocarbons in Cygnus X, a highly active star-forming region in the Milky Way. The findings, published in The Astrophysical Journal, support the theory that interstellar ice forms on dust particles, which are shielded from ultraviolet radiation by dense dust clouds. SPHEREx, launched in March 2025, is the first infrared mission designed to detect such molecules across the entire sky. The mission is managed by NASA's Jet Propulsion Laboratory and involves a team of scientists from the U.S., South Korea, and Taiwan.
