JWST discovers new Uranus moon S/2025 U1 — a ~6-mile satellite between Ophelia and Bianca

Using near‑infrared images from the James Webb Space Telescope taken in February, NASA and Southwest Research Institute astronomers identified a new tiny Uranian moon, designated S/2025 U1. Estimated at ~6 miles across, it orbits about 35,000 miles from Uranus between Ophelia and Bianca and awaits IAU naming.

JWST images Butterfly Nebula: dying star producing PAHs that may seed exoplanets The James Webb Space Telescope has imaged the Butterfly Nebula, revealing the dying central star is producing abundant polycyclic aromatic hydrocarbons (PAHs). These large hydrocarbons could play a key early role in prebiotic chemistry and may help seed forming exoplanetary systems.

JWST NIRCam Spots Candidate Signals at Epsilon Eridani, Instrument Noise Prevents Planet Confirmation James Webb's NIRCam recorded features near Epsilon Eridani—one of the nearest Sun-like stars long suspected to host a planet—but the detections lie close to known instrument noise artifacts, preventing a definitive exoplanet claim; results were published on arXiv and highlight direct‑imaging limits.

JWST Uncovers Dormant 'Sleeping Beauty' Galaxies in the First Billion Years NASA’s James Webb Space Telescope has identified a population of quiescent galaxies spanning a wide mass range less than a billion years after the Big Bang. These ‘Sleeping Beauty’ systems challenge models of early galaxy growth by showing massive galaxies halted star formation far earlier than expected.
