The James Webb Space Telescope (JWST) has produced unprecedented near-infrared images of the Bullet Cluster, a collision of two galaxy clusters 3.8 billion light-years away.
These observations have allowed scientists to create the most detailed mass maps of the Bullet Cluster to date, providing deeper insights into dark matter distribution.
By analyzing gravitational lensing, researchers have pinpointed the location of dark matter, revealing its close alignment with the distribution of galaxies.
The findings, published in The Astrophysical Journal Letters on June 30, 2025, offer stronger constraints on dark matter properties.
Understanding dark matter's behavior is crucial for accurate models of cosmic evolution.
