Uranus and Neptune may look like planetary twins, but their origins could be surprisingly different. By analyzing atmospheric carbon monoxide and oxygen levels, researchers found evidence that Neptune may have formed closer to the Sun before migrating outward, while Uranus likely developed near its current location.

These chemical clues could reshape our understanding of the solar system’s formation, but future missions to these distant ice giants will be needed to confirm their mysterious past.
