Scientists recently analyzed a meteorite Today sample after a recent fall and made some exciting discoveries! ¹ The meteorite, called the Winchcombe meteorite, fell to Earth in February 2021 and is a rare type of meteorite called a CM carbonaceous chondrite.
Key Findings:
- Composition: The meteorite contains approximately 11% extraterrestrial water and extra-terrestrial amino acids, which are prebiotic molecules that are fundamental components for the origin of life.
- Origin: The meteorite is thought to have originated from a primitive asteroid in the asteroid belt and is believed to have been formed in the early days of the solar system.
- Magnetic Properties: The meteorite has a unique magnetic composition, with a high abundance of a magnetic phase called magnetite, which suggests that it had a unique history.
- Implications for Life on Earth: The discovery of extraterrestrial amino acids and water in the meteorite supports the theory that meteorites catalyzed the emergence of life on Earth.
These findings are significant because they provide insights into the early solar system and the origins of life on Earth. The analysis of the Winchcombe meteorite is ongoing, and scientists are excited to learn more about this rare and primitive meteorite ¹.
