An infrequent celestial event from 3,000 years ago in deep space might become visible to the naked eye this year as T Coronae Borealis, a giant star, is set to explode. Astronomers predicted its nova in 2024, recurring every 80 years. A nova causes a brief, significant increase in brightness. NASA astronomer Bill Cooke likened observing this to a solar eclipse, describing it as a once-in-a-lifetime experience.
