- What is "Supernova"?
Answer : Option D
Explanation :
The most likely 'cannon' is the explosive kick of a supernova, one of the Universe's most titanic events. When massive stars end their lives, they explode violently as supernovae. They leave either a neutron star or a black hole as a remnant, depending on how massive the star initially is.
