What is certain, however, is that the size, composition, and orbit of Earth changed as a result—and that the impact marked the birth of our constant companion in space, the moon. ... read full post
High-energy cosmic radiation damages cells and DNA, causing cancer, and secondary neutrons—generated especially from the planetary surfaces—can be up to 20 times more harmful than other radiations. Aluminum, the most widely used shielding material, has the drawback of generating additional secondary neutrons when below a certain thickness. ... read full post
