Asteroid Chemistry Reveals Earth’s Secret Ingredient for Life

Zinc in meteorites reveals Earth’s essential volatiles came from unmelted asteroids, crucial for life. This insight may guide the search for life on other planets. Researchers have analyzed the chemical signatures of zinc in meteorites to trace the origin of Earth’s volatile elements. Their findings indicate that without contributions from ‘unmelted’ asteroids, Earth might have [...]
