Astronomers found direct evidence of "monster stars" in the early universe, solving a 20-year mystery about supermassive black hole formation. Using the James Webb Space Telescope, scientists detected an extreme nitrogen-to-oxygen ratio in galaxy GS 3073, indicating the presence of stars 1,000 to 10,000 times the Sun's mass. These massive, short-lived stars collapsed into black holes, potentially seeding the supermassive black holes observed today.
