Iron From Supernova Found on Earth’s Moon

Confirming a supernova explosion in the neighbourhood of our solar system, physicists at the Technical University of Munich (TUM) in Germany and colleagues have found supernova iron found on the moon’s surface. They succeeded in demonstrating an unusually high concentration of radioactive 60Fe isotope – created almost exclusively in supernova explosions – in lunar ground samples. The samples were gathered between 1969 and 1972 during Apollo lunar missions 12, 15 and 16 which brought the lunar material back to earth. Since the moon generally provides a better cosmic record than…
