AI Summary

Astronomers using the James Webb Space Telescope have confirmed the existence of a massive, dust‑rich galaxy named Leviathan in the early universe. The galaxy is observed at a time when the cosmos was about 1.5 billion years old. Unlike typical early massive galaxies, Leviathan’s stars are distributed over a wide area rather than being tightly concentrated, challenging the notion that dusty giants quickly evolve into compact systems.
