JWST recently turned up hundreds of free-floating rogue planets in the Orion Nebula, 42 in binary configurations. How two Jupiter-mass objects could end up orbiting one another has puzzled astronomers, but now a team of researchers thinks they know it happens. Large, hot stars in the Orion Nebula blasted the outer layers of smaller stars, eroding them away and preventing them from gaining enough mass to ignite fusion in their cores - even binary stars.
