Day 7 of the 2025 Space Telescope Advent Calendar: A Warped View Through an Einstein Ring

ESA / Webb, NASA & CSA, G. Mahler Day 7 of the 2025 Space Telescope Advent Calendar: A Warped View Through an Einstein Ring. You are seeing two galaxies here, one in front of the other. The more distant spiral galaxy appears warped and distorted due to the gravitational lensing occurring around a massive, much closer galaxy, which is part of galaxy cluster SMACSJ0028.2-7537.
