The Blaze Star: Waiting on a Once-in-80-Years Nova - Astronomy Class
Presenter: Dr. Wes Ryle
Somewhere in the constellation Corona Borealis, a white dwarf has spent decades quietly siphoning material from its red giant companion — and when it finally reaches its breaking point, the resulting explosion will briefly rival the North Star in brightness. Astronomers have been watching T Coronae Borealis, nicknamed the "Blaze Star," all year for an eruption that's been building since its last outburst in 1946, itself almost exactly 80 years after the one before it in 1866. It could ignite any night now — possibly even before we gather for class. Learn the physics behind this rare stellar explosion, how to spot it for yourself once it happens, and why astronomers can be so confident it's coming without knowing the exact night.
