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.

Rectangular-aperture telescope could detect half of nearby Earth-sized planets in under three years A proposed rectangular-aperture space telescope concentrates collecting area in one dimension, enabling a compact instrument that, according to the study, could detect roughly half of Earth-sized planets orbiting Sun-like stars within 30 light‑years in under three years. The design aims to accelerate target selection for JWST- and Roman-era characterization.

JWST detects unusually rich planet-forming disk around a brown dwarf James Webb observations reveal an unusually massive, chemically rich protoplanetary disk circling a brown dwarf, offering a rare, detailed view of planet-forming chemistry in extreme low-mass environments. The findings could reshape expectations for the types and diversity of planets that form around substellar objects.

JWST captures thousands of newborn stars in dramatic star‑forming 'mountaintop' image NASA’s James Webb Space Telescope released a new infrared image showing thousands of newborn stars clustered in a dense, glowing wall of gas and dust — a 'craggy, starlit mountaintop' of star formation that reveals fine structures in stellar nurseries only JWST can resolve.

JWST MIRI captures red, long-wavelength view of the universe’s first galaxies Images from JWST's MIRI instrument capture the universe's earliest galaxies in long-wavelength infrared for the first time, revealing a population of red, dusty or evolved systems. A new Astronomy & Astrophysics study uses these data to refine models of galaxy formation more than 13 billion years ago.

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.
