Target entity: SN 1604
Context triple: [SN 1987A, firstNakedEyeSupernovaSince, SN 1604]
  • A. SN 1572
    SN 1572 is a historically significant supernova in the constellation Cassiopeia whose detailed observations by Tycho Brahe helped challenge the Aristotelian view of an unchanging heavens.
  • B. SN 1961V
    SN 1961V is a peculiar and debated astronomical transient in the galaxy NGC 1058, long argued to be either an unusual supernova or a super-outburst of a luminous blue variable star.
  • C. SN 1987A
    SN 1987A is a famous supernova, the closest observed in modern times, whose 1987 explosion in the Large Magellanic Cloud has provided key insights into stellar death and supernova physics.
  • D. Great Comet of 1577
    The Great Comet of 1577 was a bright, widely observed comet whose precise measurements by Tycho Brahe helped demonstrate that comets travel through the celestial spheres, challenging the prevailing Aristotelian cosmology.
  • E. supernova SN 1954J
    Supernova SN 1954J is a mid-20th-century stellar explosion event in an external galaxy that became notable through detailed optical observations and analysis by astronomers.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
