NASA's Chandra X-ray Observatory captured a rare image of a merging galaxy cluster, revealing hot gas and dark matter dynamics during a violent cosmic collision.
NASA's Chandra X-ray Observatory has captured a new image of the "Champagne Cluster," a rare merging galaxy cluster discovered on December 31, 2020.
The composite image, showing superheated gas in purple and optical data in color, reveals two massive clusters colliding, with hot gas stretching vertically and dark matter playing a key gravitational role.
Scientists are uncertain whether the merger occurred about 400 million years ago or involved a prior collision over two billion years ago followed by a re-collision.
The findings, published in The Astrophysical Journal, aim to shed light on dark matter behavior during such violent cosmic events.
El Observatorio de rayos X Chandra de la NASA capturó una imagen rara de un cúmulo de galaxias que se fusiona, revelando la dinámica del gas caliente y la materia oscura durante una violenta colisión cósmica.
