<h3>
What is Supernova?</h3>
- The enormous and dazzling explosion of a star is known as a supernova.
- This sporadic astronomical event occurs either when a white dwarf is sent off into uncontrollable nuclear fusion or in the latter stages of the formation of a massive star.
- The initial object referred to as the progenitor either entirely vaporizes or falls into a neutron star or black hole.
- A supernova's peak optical luminosity can be comparable to that of an entire galaxy before diminishing over the course of a few weeks or months.
- The most recent supernova remains have been found, although Kepler's Supernova, which happened in 1604, was the last one in the Milky Way that could be directly observed.
