This is El Gordo, a NIRCam medium deep field of a galaxy cluster contains hundreds of galaxies that existed when the universe was 6.2 billion years old.
The reddish distorted "fish-hook" like galaxy, called El Anzuelo, is a far galaxy, which its light took 10.6 billion years to reach us. Its distinctive red color is due to a combination of reddening from dust within the galaxy itself and cosmological redshift due to its extreme distance.
