More than 500 free-floating planetary-mass objects have been discovered wandering through the Orion Nebula thanks to new observations by the James Webb Space Telescope (JWST).
Free-floating planetary-mass objects that do not orbit a star have been discovered in star-forming regions before, but never in the numbers seen by the JWST's Near-Infrared Camera (NIRCam). These objects are visible because they are still young and glowing with the heat of their formation.
