NASA’s SPHEREx Observatory Maps Interstellar Ice in Milky Way

What Happened

NASA/JPL-Caltech/IPAC/Hora et al.

Why It Matters

An observation made by NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) shows the chemical signatures of water ice (shown in bright blue) and polycyclic aromatic hydrocarbons (orange) in Cygnus X, one of the most active and turbulent regions of star birth in our Milky Way galaxy.

Key Details

  • The image was released on April 15, 2026, along with a study detailing the observation.
  • One of SPHEREx’s main goals is to map the chemical signatures of various types of interstellar ice.
  • This ice includes molecules like water, carbon dioxide, and carbon monoxide, which are vital to the chemistry that allows life to develop.
  • Researchers believe these ice reservoirs, attached to the surfaces of tiny dust grains, are where most of the universe’s water is formed and stored.
