INBOX ASTRONOMY NASA Webb 'Pierces' Bullet Cluster, Refines Its Mass Release date: Monday, June 30, 2025 10:00:00 AM Eastern Daylight Time Webb shows fainter and more distant galaxies, along with light from stars that trace dark matter in these galaxy clusters, helping researchers carefully map everything in the scene. It’s rare for galaxy clusters to collide and merge at high speeds. An iconic example is the Bullet Cluster, the aftermath of two vast galaxy clusters that collided. To be able to “replay” wha ...Continue Reading
