Text, November 4, 2022. Early Universe Galaxy Cluster.
A bright star surrounded by galaxies and stars.
Text, NASA's James Webb Space Telescope has detected a forming galaxy cluster in the early universe that existed 11.5 billion years ago.
Webb was investigating a known quasar, a type of active, very bright supermassive black hole that lies at the heart of a massive galaxy.
The image moves in closer.
Text, Webb confirmed three massive galaxies orbiting each other at very high speeds in the region surrounding the quasar, and there could be more.
A box comes into view of a highlighted area with the text, Emissions from doubly ionized oxygen. Four boxes to the right with different colors of light.
Text, The region around the quasar is very dense, and astronomers think it could indicate two massive regions of dark matter merging together.
Each box labels the kilometers per second.
