The James Webb Space Telescope discovered six rogue Jupiter-sized planets in the star-forming nebula NGC 1333.

The James Webb Space Telescope has detected six rogue planets, slightly larger than Jupiter, in a star-forming nebula NGC 1333, 960 light-years away. These celestial objects, not orbiting stars, provide insights into star and planet formation across the universe. The Webb telescope, capable of observing the universe in infrared light, looked through the dust obscuring previous observations by the Hubble Space Telescope, revealing newborn stars, brown dwarfs, and objects with planet-like masses within the nebula. These findings are part of a study accepted for publication in The Astronomical Journal.
