Day 11 of the 2025 Space Telescope Advent Calendar: Looking for Signs of a Black Hole. Spiral galaxy M83, also known as the Southern Pinwheel, lies about 15 million light-years away from Earth. Recent observations by the James Webb Space Telescope revealed the presence of highly ionized neon gas—evidence that suggests the presence of a long-sought supermassive black hole at the heart of the galaxy.
