Massive, Star-Forming Spiral Galaxy Discovered Similar to the Milky Way
TL;DR Summary
Astronomers using Webb and ALMA discovered a massive, well-formed barred spiral galaxy from 11 billion years ago forming stars at 300 times the rate of the Milky Way, without signs of collision, challenging previous theories that such extreme star formation was caused by galactic mergers. The galaxy's bar structure, rich in gas, appears to drive intense central starbursts through gas inflows from the cosmic web, providing new insights into galaxy evolution in the early universe.
