    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.

    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.

    In 1955, optical engineer and amateur archaeologist William C. Miller proposed that this represents a conjunction between the moon and the supernova, made possible by the fact that, seen from the Earth, the supernova occurred in the path of the Ecliptic. On the morning of 5 July, the moon was located in the immediate proximity of the supernova ...

    At a distance of around 12 million light years, the supernova is one of the nearest to be observed in recent decades. [75] A few weeks after a star exploded in the spiral galaxy NGC 2525 during the month of January 2018, NASA's Hubble Space Telescope took consecutive photos for nearly a year of the resulting Type Ia supernova, designated as SN ...

    Light and neutrinos from the explosion reached Earth on February 23, 1987 and was designated "SN 1987A" as the first supernova discovered that year. Its brightness peaked in May of that year, with an apparent magnitude of about 3. It was the first supernova that modern astronomers were able to study in great detail, and its observations have ...
