    As seen from Earth, Betelgeuse as a type II-P supernova would have a peak apparent magnitude somewhere in the range −8 to −12. [183] This would be easily visible in daylight, with a possible brightness up to a significant fraction of the full moon, though likely not exceeding it. This type of supernova would remain at roughly constant ...

    The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.

    Intermediate "super-AGB" stars, around 7-9 M ☉, can undergo carbon fusion and may produce an electron capture supernova through the collapse of an oxygen-neon core. [ 24 ] Main-sequence stars, burning hydrogen in their cores, with masses between 10 and 30 or 40 M ☉ will have temperatures between about 25,000K and 32,000K and spectral types ...
