Scientists Discover 'Impossible' Rogue Planets in Orion Nebula

James Webb telescope observed massive, starless planets called "JuMBOs" in Orion Nebula.
JuMBOs break planetary formation theories as they orbit each other without a host star.
Interactions with young stars likely ejected JuMBOs into space.
JuMBOs have orbits that can take up to 20,000 years to complete.
Discovery sheds new light on planet formation mechanisms and rogue planetary objects.
