Earth’s Core Revealed by Seismic Waves: Layered Truth
Introduction: A Layered View of Earth’s Core Recent seismic analyses have transformed our understanding of Earth’s iron heart. By tracking how seismic waves travel through and around the inner core, scientists are uncovering a layered structure that behaves like an onion—and sometimes in surprising, counterintuitive ways. The new findings suggest not only a multilevel inner…

Proto Earth Clues: 4.5-Billion-Year Signatures Unearthed by MIT Team
Uncovering the very beginnings of Earth Geologists from MIT and partner institutions report a groundbreaking discovery: remnants of the so-called “proto Earth” that formed about 4.5 billion years ago. The find centers on a subtle, but telling, isotopic imbalance in potassium found in some of Earth’s oldest rocks, suggesting a material that predated the planet’s…
