-
A.
SN 2004dj
SN 2004dj is a relatively nearby Type II-P supernova discovered in 2004 in the spiral galaxy NGC 2403, notable for being one of the brightest and closest core-collapse supernovae observed in recent decades.
-
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 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.
-
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.
SN 1604
SN 1604, also known as Kepler's Supernova, was a historically significant stellar explosion observed in 1604 that became one of the brightest recorded supernovae in the Milky Way.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
