Webb Peers into Heart of Circinus Galaxy

The Hubble image shows the Circinus Galaxy, a spiral galaxy about 13 million light-years away in the southern constellation of Circinus; a close-up of its core from Webb shows the inner face of the hole of the donut-shaped disk of gas disk glowing in infrared light; the outer ring appears as dark spots.

Astronomers using NASA’s James Webb Space Telescope have captured the most detailed infrared view yet into the center of the Circinus Galaxy, one of the closest known active galaxies to the Milky Way. The Webb observations suggest that much of the hot dust near the galaxy’s supermassive black hole is feeding the black hole itself, rather than being expelled outward in powerful flows as previous models had predicted. The Hubble image shows the...

The Champagne Cluster appears here as a large collection of brilliant white lights, each a distinct galaxy. A neon purple cloud stretches across the cluster’s crowded core. Many of the hundred-plus galaxies in the cluster are in two clumps of galaxies towards the top and bottom of center. Some are encircled by a faint glowing haze, while a few foreground stars gleam with diffraction spikes. Some of the smaller galaxies are tinted blue, orange, or red, and some appear more oblong than round, suggesting spiral shapes viewed edge-on. The neon purple cloud sits at the heart of the image, surrounding the most densely-packed part of the cluster. This cloud, which spreads vertically across the cluster, is multimillion-degree gas observed by Chandra. The two clumps of observable galaxies, and the spread of superheated gas, reveal that the Champagne Cluster is in fact two clusters in the process of colliding.
