At some point in Earth’s history, chemistry transitioned from abiotic organic synthesis—the building of more complicated organic molecules from smaller ones by nonbiological means—to biochemistry.

The Goldilocks Problem For Detecting Water In Terrestrial Planets: Constraining Water Abundances In The mid-IR With LIFE
![[L] The detrended and phase-folded RV time series of GJ 1132 b (top) and GJ 1132 c (bottom). Different draws of the Keplerian models from our posterior are superimposed in black. The different colored markers correspond to different RV time series. Binned data points are shown as red squares.

![Artist’s impression of the simulations conducted in this research. Jupiter (lower left) has a strong magnetic field which creates a cavity in its circumplanetary disk. Saturn (upper right) lacks a strong magnetic field so its circumplanetary disk evolves without a cavity. Credit: Yuri I.
