By creating Earth's conditions from 4 billion years ago, scientists can narrow the chemical reactions that could have taken place then – including those that may have been critical to the emergence of life here, or that might signal life elsewhere. https://go.nasa.gov/3Zx7JYF #NASAExoplanets
A specialized laboratory setup at JPL removes the chemical influence of modern organisms so scientists can study the chemistry that may have led to life’s emergence.
