The James Webb Space Telescope (JWST) has identified half a dozen free-floating planets wandering alone in the Perseus Molecular Cloud.
The planets, ranging between five and 10 times the mass of Jupiter, don't orbit a star themselves. Instead, they are all thought to have formed like stars, condensing directly out of interstellar gas. In an added twist, one of the rogue planets is encircled by a disk of gas and dust that is forming moons or, perhaps,
"mini-planets."
