(Phys.org) —A combined team of researchers from Lawrence Livermore National Laboratory and Arizona State University has found isotopic evidence of a supernova inside of a meteorite that fell to Earth in 1969. In their paper published in Proceedings of the National Academy of Science, the team describes how isotopes found in the Allende meteorite differ from those found on Earth or on the moon, suggesting they came directly from a supernova rather than from a debris field that followed.
