Target entity: SN 1968L
Context triple: [Messier 83, supernovaeObserved, SN 1968L]
  • A. 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.
  • B. 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.
  • C. SN 1993J
    SN 1993J is a well-studied Type IIb supernova that occurred in the nearby galaxy Messier 81 and became one of the brightest and most extensively observed supernovae of the late 20th century.
  • D. 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.
  • E. V838 Monocerotis
    V838 Monocerotis is a peculiar variable star best known for its spectacular 2002 outburst and subsequent expanding light echo, which produced some of the most striking astronomical images ever captured by the Hubble Space Telescope.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
