The last recorded outburst was in 1946. When it explodes, it will be in the top 50 brightest stars in the night sky, astronomers say. ????? ???????  

The explosion of T Coronae Borealis, a recurring NOVA, only happens once every 79 to 80 years, according to NASA. It is one of 10 known recurring novas in the Milky Way that erupt on timescales of less than a century. ????????????

It is difficult to predict the exact date of explosion, Louisiana State University physics and astronomy professor Bradley Schaefer, told ABC News last year. ?????  

In June, NASA predicted that the Blaze Star could explode before September. Another prediction came in October, when astronomers at the Paris Observatory predicted that the explosion would happen on March 27, 2025. ????? ???????  

Stargazers watched the skies with bated breath on Thursday night in hopes that T Coronae Borealis, a system consisting of a hot, red giant star and a cool, white dwarf star about 3,000 light-years away, would be visible with the naked eye once the explosion occurred. ????????????
