T Coronae Borealis, also known as the "Blaze Star," is actually a pair of stars located 3,000 light-years away. The star system is a recurring nova, with Earth-visible explosions every 79 to 80 ...
According to NASA, the T Coronae Borealis, nicknamed the Blaze Star, lies 3,000 light years away from Earth and is a recurring nova with outbursts every 80 years. It’s last outburst was in 1946 ...
A rare nova explosion will soon be visible in the Earth’s nighttime sky, according to officials at NASA. ... The last time a T CrB nova was seen from Earth was in 1946. ... This results in a ...
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 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.

This is among the earliest supernovae caught after detonation, and it is the earliest for which spectra have been obtained, beginning six hours after the actual explosion. The star is located in a spiral galaxy named NGC 7610, 160 million light-years away in the constellation of Pegasus. [37] [38]
The star system, located 3,000 light-years from Earth and typically too dim to be seen with the naked eye, is expected to reach a level of brightness similar to that of Polaris, or the North Star.
