Leviathan's sprawling stars challenge idea that dusty giants become compact galaxies

Leviathan's sprawling stars challenge idea that dusty giants become compact galaxies

Astronomers using the James Webb Space Telescope (JWST) have confirmed a massive, dust-rich galaxy called Leviathan in the early universe. Seen when the universe was roughly 1.5 billion years old, the galaxy has its stars spread out rather than in a concentrated fashion. A paper, describing its strange stellar distribution, was posted to the arXiv preprint server on Oct. 19.
