Space scientists from the University of New Hampshire and multi-institutional colleagues report they have quantified levels of radiation on the moon’s surface from galactic cosmic ray (GCR) bombardment that over time causes chemical changes in water ice and can create complex carbon chains similar to those that help form the foundations of biological structures.

Analysis of deposits on Mars reveals extended lakes and shorelines
