Below two images of the Galaxy NGC 514 area.
- In the top image, a single 300s unfiltered capture acquired the Oct 23th 2020, marked in the center with a visual magnitud ~13.5, the Type Ia supernovae 2020 uxz. This type of supernovae are super energetic final destructive event for some stars resulting from the collapse of a white dwarf when it gets the Chandrasekhar limit and becomes unstable exploding violently. From here the star will evolve to either a black hole or more likely to a neutron star.
- Just below the previous one the much older image from (c) The Digitalized Sky Survey NIR released May 2019 database. Obviously both stars and galaxy are much more prominent since the professional instruments used are much more sensitive, but even in that case, there is no trace of any star at the supernovae position.

Below some basic spectroscopic low resolution analysis of the supernovae. Typical supernovae Ia absorption features identified for Si and Fe:

Impresionante!
