Webb Telescope Maps Uranus's Auroras in 3D; Hubble Finds Galaxy 99% Dark Matter

The Webb Telescope's first 3D mapping of Uranus's auroras advances planetary magnetism studies, highlighting the capabilities of next-generation observation. Meanwhile, Hubble's discovery of a galaxy with 99% dark matter challenges current models of cosmic composition. Both findings exemplify space exploration's rapid progress and indicate areas for future research, such as comparative planetary atmospheres and dark matter distribution.
