Dust and Water in Sagittarius A*

A dense star field fills the entire image, with countless stars scattered across a backdrop of glowing clouds in shades of red, orange, pink, white, and blue. At the center, a brilliant concentration of stars creates a bright, almost white core surrounded by intricate filaments and wisps of illuminated gas and dust that radiate outward. Dark, irregular patches of opaque dust interrupt the glowing clouds, particularly toward the left side of the image, where they appear as silhouetted shapes against the brighter background. The surrounding stellar population varies in brightness and color, with cool blue stars and warmer orange and red stars distributed throughout the scene.

A brilliant concentration of stars takes center stage in this Aug. 11, 2026, image taken by NASA’s James Webb Space Telescope. Webb observed IRS 3, a star near the end of its life cycle, located within this starfield. Webb’s mid-infrared data revealed the clear signature of oxygen-rich silicate dust, as well as, for the first time, water, in its surrounding dust envelope.
