    If Betelgeuse were too close to Earth, the eventual supernova could cause an extinction here on Earth. However, even at 530 light-years distance, our planet will still be safe from the eventual ...

    As seen from Earth, Betelgeuse as a type II-P supernova would have a peak apparent magnitude somewhere in the range −8 to −12. [176] 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 (pc) [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.

    Comparison of VLT-SPHERE images of Betelgeuse taken in January 2019 and December 2019, showing the changes in brightness and shape. Betelgeuse is an intrinsically variable star. A variable star is a star whose brightness as seen from Earth (its apparent magnitude) changes systematically with time.

    Damian Lillard is the only one going supernova these days. The Hubble Space Telescope revealed why nearby red giant star Betelgeuse became surprisingly dim late last year, according to a new study.

  8. Supernova - Wikipedia

    en.wikipedia.org/wiki/Supernova

    A near-Earth supernova is a supernova close enough to the Earth to have noticeable effects on its biosphere. Depending upon the type and energy of the supernova, it could be as far as 3,000 light-years away. In 1996 it was theorised that traces of past supernovae might be detectable on Earth in the form of metal isotope signatures in rock strata.
