Scientists detect small pockets of carbon dioxide-rich liquid water in a meteorite dating from the early solar system

Caption

(A) Inclusions in a calcite grain in the Sutter's Mill meteorite recognized by X-ray nanotomography. Fluids were not detected in relatively large inclusions as they had already escaped. (B) TEM image of a non-inclusion filled with CO2-bearing fluid (indicated by arrow). (C) H2O, CO2, and CO snow lines and Sutter's Mill parent body formation. The formation region can be estimated from the presence of the CO2-bearing fluid. Nebular accretion rate, ?, corresponds to the time axis for the evolution of the early solar system.
