Carbonaceous Chondrite: A primitive meteorite class characterized by high carbon content, volatile elements, and chondrules, often containing organic compounds.
Bulk Density: The total mass of an object divided by its total volume, including any internal voids or pores.
Solar Nebula: The rotating disk of gas and dust from which the Sun and planets of our solar system formed approximately 4.6 billion years ago.
Abiogenesis: The natural process by which life arises from non-living matter, such as simple organic compounds.
