Extraterrestrial materials

Extraterrestrial materials are substances that originate from outside Earth, such as meteorites, comets, and cosmic dust. These materials provide valuable insights into the composition, formation, and history of our solar system and beyond. They can be made of rock, metal, or ice, often preserved in space for millions or billions of years. Scientists study them to understand planetary processes, the origins of life, and the universe's evolution. By analyzing extraterrestrial materials, we gain a deeper knowledge of how celestial bodies form and interact across the cosmos.
