Webb Telescope Reveals 'Little Red Dots' May Be Hidden Galaxies

Astronomers using NASA's James Webb Space Telescope have found a clue to the mysterious 'little red dots' observed in the early universe. By studying a nearby spiral galaxy, the 'Saguaro,' researchers discovered a compact, bright red center resembling these distant objects, but surrounded by a full galaxy. Simulations suggest that from afar, the spiral structure would vanish, leaving only the red core, indicating these dots could be a temporary phase of highly active supermassive black holes within entire galaxies.
