Astronomers say a 'once-in-a-lifetime' view of an astronomical explosion is expected any night with T Coronae Borealis, a recurring nova with visible explosions every 79 to 80 years.
When the explosion comes into Earth's view, it's going to be one of the brightest stars in the sky according to Louisiana State University professor Bradley Schaefer.
The exact day and time of the explosion are 'unknown', but historical behavior and current pre-eruption dip of T Coronae Borealis indicate the view of the explosion is imminent.
