The star that should have exploded already: T Coronae Borealis | ESO

T Coronae Borealis, nicknamed the Blaze Star, erupts every 80 years or so, becoming visible to the naked eye. Based on recent behavior the star should have flared again in late 2024, but it did not! Astronomers are thus eagerly waiting for this imminent explosion. In this episode of Chasing Starlight we tell you how professional telescopes can quickly react to sudden cosmic events like this one.

T Coronae Borealis (T CrB), nicknamed the Blaze Star, is a binary star and a recurrent nova about 3,000 light-years (920 pc) away in the constellation Corona Borealis.
