Question Mark Galaxy – Hubble and Webb

NASA’s Hubble Space Telescope has also observed the galaxy cluster MACS-J0417.5-1154, but the dusty red galaxy that appears multiple times to form a question mark shape is much more prominent in the Webb image. The infrared light that Webb detects is better able to pass through the cosmic dust of its home galaxy to reach the telescope. Astronomers used Hubble’s ultraviolet observations to help determine where star formation is happening in both the red galaxy and its close companion, a face-on spiral galaxy.
