Tiny Moon NASA's James Webb Space Telescope has spotted a tiny moon orbiting Uranus, expanding the number of the planet's known satellites to 29. In early February, the space observatory's Near-Infrared Camera (NIRCam) caught the minuscule and still-unnamed object orbiting Uranus' center at a distance of 35,

Planet could be a gas giant, orbiting 1 to 2 times the distance between Sun and Earth. The Alpha Centauri system, our nearest stellar neighbor, has long captured the imagination of science fiction and

The TRAPPIST-1 system, home to seven Earth-sized planets orbiting a red dwarf star, has long been a target for astronomers studying potentially habitable exoplanets. Among these, TRAPPIST-1 d stood out as a promising candidate due to its position within the habitable zone of its host star,

The space around Uranus just got a bit more crowded. On Tuesday, astronomers using the James Webb Space Telescope announced the discovery of a moon orbiting around the pale blue ice giant, bringing its total number of satellites to 29.

Scientists think the new tiny moon hid for so long -- even eluding the Voyager 2 spacecraft during its flyby about 40 years ago — because of its small size.
