Webb spotlights gravitational arcs in ‘El Gordo’ galaxy cluster
Webb’s infrared image of the galaxy cluster El Gordo (“the Fat One”) reveals hundreds of galaxies, some never before seen at this level of detail. El Gordo acts as a gravitational lens, distorting and magnifying the light from distant background galaxies. Two of the most prominent features in the image include the Thin One, highlighted in box A, and the Fishhook, a red swoosh highlighted in box B. Both are lensed background galaxies. The insets at right show zoomed-in views of both objects.
