Earth’s origin mystery cracked? Meteorites may hold the secret to life’s ingredients |– timesofindia.indiatimes.com

Scientists involved in planetary formation studies, meteorites, and early solar system investigations have been wondering about the origins of the ingredients that made up the planet Earth. Studies on carbonaceous chondrites, isotopic compositions, and planetary accretion have shown that the elements needed for life on Earth, such as carbon, water, and volatiles, could have come from primitive meteorites that developed in the outer solar system. These studies have contributed to the understanding of how terrestrial planets acquired their life-giving ingredients. Scientists are finding clues to the chemical makeup of Earth through studies of isotope ratios of certain elements like molybdenum and hydrogen.
