New Star Will “Explode” in the Night Sky—How to See the “Once-in-a-Lifetime” Event


2024 promises a rare celestial treat as T Coronae Borealis (T CrB), a binary star system, is set to undergo a spectacular nova outburst. This event, not seen since 1946, will see T CrB’s brightness increase dramatically, potentially matching the luminosity of Polaris, the North Star. The system, comprising a white dwarf and a red giant, will exhibit a thermonuclear reaction due to material transfer from the red giant to the white dwarf, resulting in the nova explosion. Visible to the naked eye, the nova is expected to peak in brightness and remain observable for over a week. While the exact timing is uncertain, NASA anticipates the explosion to occur before September 2024. Stargazers can locate the event in the constellation Corona Borealis, flanked by Hercules and Bootes. This rare occurrence offers a unique opportunity for observers to witness a star’s explosive transformation.
