(Phys.org)—Many scientists believe that a cataclysmic series of impact events called the Late Heavy Bombardment (LHB) occurred around 4.1 to 3.9 billion years ago, during which there was a spike in asteroids colliding with ...
The moon was exposed to a heavy bombardment of asteroids 3.9 billion years ago. The origin of this bombardment, however, was previously unclear. Planetologists at Münster University have now tested these hypotheses with ...
