摘要：

A dying massive star ends in a supernova explosion ejecting a large fraction of its mass into the interstellar medium. If this happens nearby, part of the ejecta might end on Solar System bodies and, in fact, radioactive Fe-60 has been detected on the Pacific ocean floor in about 2 Ma old layers. Here, we report on the detection of this isotope also in lunar samples, originating presumably from the same event. The concentration of the cosmic ray produced isotope Mn-53, measured in the same samples, proves the supernova origin of the Fe-60. From the Fe-60 concentrations found we deduce a reliable value for the local interstellar fluence in the range of 1 x 10(8) at/cm(2). Thus, we obtain constraints on the recent and nearby supernova(e).
