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 event, which could occur anytime between now and September, is creating a buzz within ...
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 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 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.
RX J1856.5−3754 is thought to have formed in a supernova explosion of its companion star about one million years ago and is moving across the sky at 108 km/s. It was discovered in 1992, and observations in 1996 confirmed that it is a neutron star, the closest to Earth discovered to date.
NASA has predicted that a "once-in-a-life-time" star explosion -- or nova -- will be visible to the naked eye sometime this summer.
