Printed on everlasting aluminum, 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, located just below and left of the image center, and the Fishhook, a red swoosh at upper right. Both are lensed background galaxies.
