Astronomers discovered a Dark Matter bridge connecting the Perseus Cluster to a subcluster of galaxies, resolving a long-standing mystery in astronomy.
The international team of astronomers, led by Kim HyeongHan from South Korea, made this discovery using the Subaru Telescope at Maunakea, Hawaii.
The research paper titled 'Direct Evidence of a Major Merger in the Perseus Cluster' was published in Nature Astronomy on April 16th, 2025.
The Dark Matter bridge, 1.4 million light-years from the Perseus Cluster's core, is approximately 200 trillion times the mass of the Sun and provides evidence of past gravitational interactions.
