What is the image about?

  • Webb's first deep field galaxy cluster is SMAC 0723 which is filled with thousands of galaxies including the weakest objects seen in the infrared.

  • The image of Webb is about the size of a grain of sand held on a hand, a tiny piece of the vast universe.

  • The collection also includes fresh images of another galaxy cluster known as Stephen's Quintet, first discovered in 1877.
