NASA's James Webb Space Telescope has detected a new moon, S/2025 U1, orbiting Uranus. This tiny moon, only 10 kilometers in diameter, was missed by Voyager 2 nearly four decades ago. The discovery, made using Webb's Near-Infrared Camera, increases Uranus' known moons to 29, providing insights into the planet's complex moon and ring system and its dynamic history.

NASA's James Webb Space Telescope has potentially identified 300 ancient objects, possibly early galaxies formed shortly after the Big Bang. These unusually bright and developed structures challenge existing models of galaxy formation, suggesting a faster development timeline in the early universe. Confirmation through further spectroscopic analysis is crucial to solidify this groundbreaking discovery.
