🪐 In the galaxy cluster Abell 1689, scientists have mapped how dark matter bends light from even more distant galaxies in a phenomenon called gravitational lensing. This cosmic "magnifying glass" effect lets astronomers trace the otherwise invisible dark matter—an unknown substance that reveals itself only through gravity, helping piece together how vast amounts of hidden mass shape entire clusters across the universe. ✨ #darkmatter⚡#abell1689⚡#lensing⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 The galaxy cluster Abell 1689, located about 2.2 billion light-years from Earth, has helped astronomers map out enormous amounts of dark matter—an invisible substance that makes up most of the cluster’s mass but can only be detected through its gravitational effects. By observing how Abell 1689 bends and magnifies the light from galaxies behind it (a phenomenon called gravitational lensing), scientists reveal a hidden universe shaped by something we still can't see. ✨ #darkmatter⚡#abell1689⚡#clustering⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries
