New James Webb Space Telescope images show a massive galaxy cluster that bends light

In the dance of dark matter, NASA’s Deep Space Observatory has captured light bending in the distant universe.

The James Webb Space Telescope’s massive mirror used the gravity of the galaxy cluster to look at a known galaxy in the background, but there’s a twist: New research published Wednesday (October 26) suggests Webb may have been observing two galaxies, not one. (The area has been imaged before by the Hubble Space Telescope, but this new view is sharper than ever.)
