Story summary

New observations from the James Webb Space Telescope (JWST) show free-floating planetary-mass objects (FFPMOs) can create miniature planetary systems.
Disks around eight FFPMOs in the Orion nebula contain hydrocarbon and silicate grains, indicating possible moon and ring formation.
These findings suggest that planetary systems can form around starless objects, enhancing our understanding of celestial dynamics.
