Last year, using the James Webb Space Telescope (JWST), astronomers made the startling discovery of some free-floating, planetary-mass objects in the Orion nebula that threw their ideas of planet and star formation into doubt. And now, new research has further deepened the mystery around these so-called Jupiter-mass binary objects, or JuMBOs. JuMBOs aren't stars, but aren't really planets either.
