Take a Tour of Pandora's Cluster

About

This video tours Pandora’s Cluster (Abell 2744), a region where multiple clusters of galaxies are in the process of merging to form a megacluster. Astronomers estimate 50,000 sources of near-infrared light are represented in this image from NASA’s James Webb Space Telescope.

The concentration of mass in Pandora’s Cluster is so great that the fabric of spacetime is warped by gravity, creating an effect that makes the region of special interest to astronomers: a natural, super-magnifying glass called a “gravitational lens” that they can use to see very distant sources of light beyond the cluster that would otherwise be undetectable, even to Webb. These lensed sources, which are particularly prominent in the lower right area, appear red in the image, and often as elongated arcs distorted by the gravitational lens.

The video also highlights a mysterious object that appears to be no more than a red dot. One theory is that this source of infrared light is a glowing disk of gas surrounding a supermassive black hole in the early universe.

Human-made No record of this work says a model made it. What this means.
