a. Moon
b. Io
c. Ganymede
d. Jupiter

ANSWER: Moon
 
Scientists have confirmed the supernova explosion in the neighbourhood of the solar system even as physicists at Technical University of Munich in Germany and colleagues have found supernova iron on the surface of the moon. Samples were gathered between 1969 and 1972. During the Apollo Lunar Missions 12, 15 and 16, lunar material was brought back to earth.
  • This discovery makes it possible to provide an inference of a distance to the supernova event.
  • Measured 60 Fe-flow matches supernova at distance of 300 light years away
  • The supernova hypothesis was first put together in 1999 by TUM researchers finding initial evidence in the deep sea crust.
