The James Webb Space Telescope (JWST) has discovered Uranus' 29th moon, provisionally named S/2025 U1. This new moon is approximately 6 to 10 kilometers in diameter, smaller than most cities or suburbs, and orbits about 56,000 kilometers from Uranus' center, just beyond its narrow inner rings. The discovery expands knowledge of Uranus and its complex satellite system, which includes moons named after characters from Shakespeare and Alexander Pope. Additionally, astronomers have observed a supernova event for the first time that revealed the inner layers of a massive star at the moment it exploded, providing unprecedented insights into stellar interiors and possibly representing a new type of supernova. Separately, JWST has captured images of a baby exoplanet, approximately five times the mass of Jupiter, forming around a young star, marking the first clear detection of such a planet in a disk with multiple rings. Other notable JWST observations include detailed infrared views of galaxies such as M51, NGC 2283, and the Butterfly Nebula (NGC 6302), with the latter revealing jets, gas, dust, and large dust grains that could contribute to planet formation. NASA's Chandra X-ray Observatory has also provided data on the Cassiopeia A supernova remnant, showing violent interior rearrangements of the star before explosion. These findings collectively highlight the advancing capabilities of JWST and other observatories in deepening understanding of planetary systems, stellar evolution, and cosmic phenomena.
