Asteroid Samples and Origins of Life
Asteroid samples fetched by NASA contain the building blocks for life and evidence of an ancient water world, supporting the theory that asteroids may have contributed to the origins of life on Earth.
Key Points
- Asteroid samples contain sodium-rich minerals, amino acids, and nitrogen
- The discovery was made possible by analyzing samples collected directly from the asteroid
- Asteroids may have played a significant role in the origins of life on Earth
Pros
- Strong evidence that asteroids may have planted the seeds of life on Earth
- Ingredients for life mingling with water almost right from the start
- Presence of amino acids, nitrogen, and parts of the genetic code found in the samples
Cons
- Need for more testing and analysis to fully understand the Bennu samples
- Uncertainty about the exact processes that led to the formation of life
