NASA Finds Evidence That Mars Devoured Huge Chunks of Other Planets
The Red Planet has a bloody history. Newly examined data from NASA's retired InSight lander suggest that there may be giant chunks of rocky material deep inside the mantle of Mars, which were lodged there after a barrage of massive objects slammed into its surface some 4.5 billion years ago. Some of these smithereens are so large, the researchers say, that they're effectively protoplanets — moon-sized objects in the early stages of becoming a planet proper.
