<ul><li>Scientists studying a still-forming planet beyond our solar system have found that its chemical makeup doesn't fully match the swirling gas and dust disk from which it formed.</li><li>The finding challenges standard models of planet formation and implies they may be overly simplistic.</li><li>The planet's atmosphere contains much less carbon and oxygen than expected, suggesting that our widely accepted picture of planet formation was too simplified.</li><li>The researchers propose two scenarios to explain the observed discrepancy and suggest that further observations of the system can provide more insights for detailed modeling.</li></ul>
