The faint light diffused throughout galaxy clusters turns out to be a precise impression of dark matter. Stars ripped from galaxies fill its gravitational scaffold like plaster into a mold. This discovery gives astronomers a direct way to study the hidden structure of the Universe, without resorting

New data from the JWST telescope on galaxy NGC 4696 in the Centaurus cluster have for the first time traced the kinematic connection between large-scale filaments and a compact circumnuclear disk with a radius of about 120 parsecs. The S-shaped structure, familiar from Hubble images, turned out to b
