An explanation as to what a type II supernova is, can be found on wikipedia. This is fine for this article but please remember Wikipedia is NOT an academic source of information.

Another interesting fediverse from @AkaSci looking at the spectrum of type II supernova SN 2023ixf.

Spectrum data for Supernova SN 2023ixf in visible light wavelengths, captured yesterday, is shown below. The spectrum is rich in blue wavelengths; it has prominent peaks at wavelengths (shown as vertical lines) associated with emissions from Hydrogen. The peaks around 475 nm are associated with He, C and N.
