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 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.
The second full orbit of Neptune around the Sun since its discovery in 1846. 2177 "First Plutonian anniversary" of Pluto's discovery, given its orbit is just under 248 Earth years. 2178 January 28 2182 September 24 With an estimated probability of 0.04%, asteroid 101955 Bennu could hit Earth. 2185 Triple conjunction Mars–Saturn [56] 2186 July 16

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.
NASA released footage on October 1 showing the supernova of a star in the spiral galaxy NGC 2525, 70 million light-years away, taken between 2018 and 2019. NASA said that at its peak, the ...
💥 What is the difference between nova and supernova? A nova is an astronomical event in which a star experiences a sudden and dramatic increase in brightness — sometimes as much as 100,000 ...
SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
