Remains of ‘Buried Planet’ Uncovered Deep Within Earth, Potentially Linked to Moon-Forming Impact

Scientists have made a fascinating discovery deep within the Earth, uncovering the remains of a ‘buried planet’ possibly linked to a moon-forming impact 4.5 billion years ago. Seismologists identified massive ‘basal mantle anomalies’ beneath the Pacific and Africa, suggesting a unique material composition. Researchers speculate these anomalies could be remnants of a planet named Theia, offering insights into Earth’s collision history and moon formation. The discovery opens new avenues for understanding celestial collisions and planetary dynamics.

The Vital Role of Giant Impacts in Planetary Formation

A recent paper outlines the vital role of giant impacts in the formation of planets, shedding light on the mysterious process of planetary formation. Astronomers are still grappling with the question of how planets come into existence within star systems,…
