New image captures galaxy cluster emerging from cosmic web

The tumultuous evolution of a galaxy cluster captured close to its formation in the cosmic web
Composite image using MUSTANG-2, Chandra, and SDSS data. The faint red glow shows the hot gas at large radii. galaxies present in MUSTANG-2 and Chandra appear as point sources (in magenta) and density of the comparatively cool gas (in blue); galaxies in optical (SDSS) data are in the foreground.

An international team of astronomers using the National Science Foundation’s Green Bank Telescope (GBT) in Green Bank, West Virginia, and the NASA’s Chandra X-ray Observatory have captured a snapshot of a massive galaxy cluster, very close to the epoch when it began to emerge from the cosmic web.
