The last recorded outburst from T Coronae Borealis -- which includes a hot, red giant star and a cool, white dwarf star -- was in 1946, according to the space agency, which forecasts it will do so again before September 2024.MARK PATERNOSTRO/SCIENCE PHOTO LIBRARY The exact day and time of the explosion are "unknown," according to Schaefer, but looking at the star system's historical behavior and current "pre-eruption dip" indicate the view of the explosion is imminent.

Schaefer has been studying T Coronae Borealis for decades, saying the chance to see the explosion from Earth with the naked eye will be "magnificent." T Coronae Borealis is one of just 10 recurring novas known in the Milky Way that erupt on time scales of less than a century, according to NASA.The agency says during the event, the star system will be similar in brightness to the North Star, Polaris, and may shine this bright for days or a week after first appearing.
