JWST confirms earliest-known supernova, detects its host galaxy from the Cosmic Dawn

James Webb has confirmed the earliest-known supernova as the source of a gamma‑ray burst and, for the first time at this distance, detected the event's host galaxy. The explosion occurred when the universe was roughly 730 million years old (≈13 billion years), and Webb's rapid follow-up corroborated other observations.

JWST spots Milky Way–like spiral 'Alaknanda' just 1.5 billion years after the Big Bang Using JWST imaging amplified by gravitational lensing, researchers — including two Indian astronomers — identified a fully formed spiral galaxy, Alaknanda, just 1.5 billion years after the Big Bang; its ordered disk, sweeping arms and rapid star formation contradict slow, chaotic early-assembly models.

JWST detects puzzling high‑energy radiation from star‑forming nursery; young stars unlikely source NASA's James Webb Space Telescope has detected unexpected high‑energy radiation emanating from a nearby star‑forming nursery. Researchers say the region's young stars "are not capable of being a source of radiation," leaving the emission's origin unexplained and prompting fresh scrutiny of early stellar environments.

JWST Detects Rapidly Feeding Supermassive Black Hole in the Infant Universe, Challenging Formation Models NASA's James Webb Space Telescope has detected a supermassive black hole actively accreting in the infant universe, a finding that contradicts prevailing formation scenarios. The observation of rapid feeding at such early epochs challenges our understanding of black hole and galaxy co-evolution and the timeline of structure formation.

JWST may have detected the universe’s first stars in a lensed source (LAP1‑B) NASA’s James Webb Space Telescope may have detected the Universe’s first stars in a source labelled LAP1‑B, combining JWST’s deep infrared sensitivity with roughly 100× gravitational magnification from an intervening galaxy cluster. The signal would be otherwise too faint for direct detection without extreme lensing.

JWST Spots “BiRD”: Massive red supermassive black hole in the early universe NASA’s James Webb Space Telescope has detected an exceptionally red, massive supermassive black hole — nicknamed “BiRD” — in the early universe. The bright red point in JWST infrared imaging signals rapid, early black‑hole growth within the first few hundred million years after the Big Bang.
