Galaxy clusters are smashing together to form ‘flaming cosmic narwhal’

Six of the most powerful astronomical observatories have captured a stunning image of Abell 2256, which is made of multiple galaxy clusters smashing together

This image by NASA?s James Webb Space Telescope?s Near-Infrared Camera (NIRCam) features the central region of the Chamaeleon I dark molecular cloud, which resides 630 light years away. The cold, wispy cloud material (blue, center) is illuminated in the infrared by the glow of the young, outflowing protostar Ced 110 IRS 4 (orange, upper left). The light from numerous background stars, seen as orange dots behind the cloud, can be used to detect ices in the cloud, which absorb the starlight passing through them.

https://webbtelescope.org/contents/media/images/2022/053/01GFRYSFM89AFADVAA0W625BSB NASA?s James Webb Space Telescope?s mid-infrared view of the Pillars of Creation strikes a chilling tone. Thousands of stars that exist in this region disappear ? and seemingly endless layers of gas and dust become the centerpiece. The detection of dust by Webb?s Mid-Infrared Instrument (MIRI) is extremely important ? dust is a major ingredient for star formation. Many stars are actively forming in these dense blue-gray pillars. When knots of gas and dust with sufficient mass form in these regions, they begin to collapse under their own gravitational attraction, slowly heat up ? and eventually form new stars. Although the stars appear missing, they aren?t. Stars typically do not emit much mid-infrared light. Instead, they are easiest to detect in ultraviolet, visible, and near-infrared light. In this MIRI view, two types of stars can be identified. The stars at the end of the thick, dusty pillars have recently eroded the material surrounding them. They show up in red because their atmospheres are still enshrouded in cloaks of dust. In contrast, blue tones indicate stars that are older and have shed most of their gas and dust.
