Is supernovae and supernova the same thing?

Supernovae is the plural of supernova. Supernovae is pronounced soo-per-noh-vee

Black holes do not create supernovae. Black holes are created from a supernovae.

A supernova can be massive but some aren't. Every supernova is a dieing star. Supernovae are exploding stars. They represent the very final stages of evolution for some stars. Supernovae, as celestial events, are huge releases of tremendous energy, as the star ceases to exist, with about 1020 times as much energy produced in the supernova explosion as our Sun releases every second.

A supernova (plural: supernovae or supernovas) is a stellar explosion that creates an extremely luminous object. Check the link given for more information.

If two stars begin to orbit. However, novae are more common that supernovae, so you can't really say if the result of a binary will be a nova or a supernova.

All the elements of the periodic table apart from hydrogen and helium are synthesised in the explosion of a supernova.

It is precisely the supernovae that created those elements and dispersed them into space. It is precisely the supernovae that created those elements and dispersed them into space. It is precisely the supernovae that created those elements and dispersed them into space. It is precisely the supernovae that created those elements and dispersed them into space.

supernovae are classified by the lines in their spectra (which indicate which elements are present). type I supernovae have no hydrogen lines, having been caused by the explosion of a star with no hydrogen envelope. type II supernovae have hydrogen lines, indicating that the exploding progenitor star had retained a significant amount of its hydrogen before its supernova. type I supernovae are further classified based on the presence of silicon lines, which are present in…

There have been several recorded supernovae in the Milky Way. The earliest recorded Milky Way supernova was SN 185 (seen, as the name implies, in 185 C.E.), and the most recent supernova recorded was SN 1604 (seen in 1604 C.E.), or Kepler's Supernova.

It was visible with the naked eye. It did not originate within the Milky Way.

It is believed that almost all elements on Earth (except hydrogen and helium) were created in supernovae.

According to prevailing astronomical theory, red dwarfs do not become supernovae, so the best answer to the question is "nonexistant."

Gravity plays a huge role in supernovae. A supernova occurs when a star at least 8 times more massive than the sun stops fusing hydrogen into helium and can no longer fight the force of gravity and implodes.

Supernovae occur at the end of a massive star's lifetime when it's nuclear fuel is exhausted and it is no longer supported by the release of nuclear energy.

Different things. A red giant fuses helium, whereas a supernova catastrophically explodes. There is no similarity.
