The star is so far away that it takes 3,000 years for its light to reach the Earth, meaning the explosion occurred before the last of the Egyptian pyramids were built.
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.
The star system is a recurring nova, with Earth-visible explosions every 79 to 80 years, according to NASA. ... Nova explosion 3,000 light-years away will be seen from Earth with the naked eye.
NASA has predicted that a "once-in-a-life-time" star explosion -- or nova -- will be visible to the naked eye sometime this summer. ... an “Earth-sized” remnant of a dead star. The starburst ...
Extremely luminous stars at near solar metallicity will lose all their hydrogen before they reach core collapse and so will not form a supernova of type II. [121] At low metallicity, all stars will reach core collapse with a hydrogen envelope but sufficiently massive stars collapse directly to a black hole without producing a visible supernova ...
The explosion had the energy of approximately 9000 type Ia supernovae if the emission was isotropically emitted, and the gas jets emitting the initial gamma rays moved at a minimum velocity of approximately 299,792,158 m/s (99.9999% the speed of light), making this blast one of the most extreme recorded.

A rare nova explosion will soon be visible in the Earth’s nighttime sky, according to officials at NASA. The event, which could occur anytime between now and September, is creating a buzz within ...
The stellar eruption will take place in a system called T Coronae Borealis, which is 3,000 light-years away from Earth. It contains two stars: a dead star, also known as a “ white dwarf ...
