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…
