Microbial Habitability During the Late Heavy Bombardment
Credit: Don Davis/NASAIn a new paper in the current issue of Nature, NAI Postdoctoral Fellow Oleg Abramov at the University of Colorado, Boulder leads a modeling study investigating the degree of thermal metamorphism of the Late Heavy Bombardment (LHB) on the crust of the young Earth. The models were designed to recreate the effect of the LHB on the Earth as a whole, with special attention to the impact on a possible subsurface or near-surface primordial microbial biosphere.
The team’s analyses revealed that there is no plausible situation in which the habitable zone could...
