Difference between Supernova and Supernovae

Key Difference: ‘Supernova’ is a singular term, and ‘supernovae’ is a plural of supernova. Supernova is the last stage of the life of a star.

Supernova/Supernovae ‘Supernova’ is a singular term, and ‘supernovae’ is a plural of supernova. Thus, it has the same meaning or description. So, the following content refers to both the terms: supernova and supernovae.

Supernova, in a simple sentence, is the last stage of the life of a star. It is basically a procedure when a star is completely destroyed because it is not able to sustain its gravity anymore. When a supernova goes up in flames a black hole is created.

Modern astronomer, UW-Madison Space Place Director Jim Lattis said that ‘there are different processes that have lead to these explosions, but the upshot is that the star is ripped apart and becomes billions of times brighter than it was before.’ It has been observed from Earth that sometimes a nearly unnoticeable star becomes one of the brightest objects in the sky. They are the supernovas.

There is no difference between supernova and supernovae, thus the description, facts, etc. will be similar.

Comparison between Supernova and Supernovae:

	Supernova	Supernovae
Term	‘Supernova’ is a singular term	‘Supernovae’ is a plural of supernova
Description	The explosion of a star, possibly caused by gravitational collapse, during which the star's luminosity increases by as much as 20 magnitudes and most of the star's mass, is blown away at a very high velocity, sometimes leaving behind an extremely dense core.	Same as Supernova
Facts	Supernovas are huge stars that eventually explode. When supernovas explode, they become massive black holes. Supernovas also sometimes become quasars rather than black holes. The creation of colorful nebulas is when supernovas explode and they shoot out billions of atoms in every direction. Some stars do not become supernovas, some become dwarf giants.	Same as Supernova
Type I	A star accumulates matter from a nearby neighbor until a runaway nuclear reaction ignites.	Same as Supernova
Type II	A star runs out of nuclear fuel and collapses under its own gravity.	Same as Supernova
Examples	It was already predicted that a black hole will be created by a supernova. The outcome after the first supernova is still uncertain.	Same as Supernova
