One of the big discoveries from JWST was the existence of free-floating Jupiter Mass Binary Objects (JuMBOs) in the Orion Nebula. Two Jupiter-like objects orbit one another without a star nearby. In a new study, researchers calculate that 50-90% of JuMBOs should be destroyed within a few million years. Since we can still see them in the Orion Nebula, many more must have formed originally, and these are just the survivors.
