Summary
Astronomers may have solved the mystery of the early universe's little red dots. Instead of hidden black holes, these objects could be supermassive stars about 100,000 times the mass of the Sun, shedding dense gas shells during powerful pulsations. The model matches James Webb Space Telescope observations, explaining their compact, nitrogen-rich appearance and suggesting these giants eventually collapsed directly into the first supermassive black holes, offering a unified origin for one of cosmology's biggest mysteries.
