James Webb Finds Evidence of Free-Floating Planets So Large They Can Gather Their Own Planetary Systems

SMRTR summary

The James Webb Space Telescope has discovered evidence of massive rogue planets potentially forming their own planetary systems without a host star. Six of eight examined free-floating planets show signs of early planetary formation, suggesting they could develop miniature solar systems with smaller planets orbiting them. This indicates planetary system formation may occur around solitary worlds drifting through space, although these dark systems would be difficult to detect.
