    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 (less than roughly 10 to 300 parsecs [33 to 978 light-years] away [2]) to have noticeable effects on Earth's biosphere.

    en.wikipedia.org/wiki/List_of_supernova_candidates

    This is a list of supernova candidates, or stars that are believed to soon become supernovae. Type II supernova progenitors include stars with at least 8~10 solar masses that are in the final stages of their evolution.

  7. Supernova - Wikipedia

    en.wikipedia.org/wiki/Supernova

    Stars with an initial mass up to about 90 times the Sun, or a little less at high metallicity, result in a type II-P supernova, which is the most commonly observed type. At moderate to high metallicity, stars near the upper end of that mass range will have lost most of their hydrogen when core collapse occurs and the result will be a type II-L ...

    The supernova was a Type Ic supernova, similar to SN 1998bw, the first supernova linked to a GRB. Lightning detectors in India and Germany picked up signs that the Earth's ionosphere was perturbed for several hours by the burst, though only mildly, [ 37 ] [ 17 ] [ 4 ] as well as an enormous influx of electrically charged particles, [ 38 ...
