After 80 years of silence, the Blaze Star may erupt again—lighting up the night sky for days with a stellar flare visible to the naked eye.
In this rare binary system, a white dwarf siphons hydrogen from a red giant, building pressure until a fiery nova explosion bursts outward.

The last known eruptions were in 1866 and 1946. Astronomers believe this ticking stellar clock is now seconds from its cosmic alarm.

When we see the nova, we’re witnessing an ancient explosion—its light having traveled 3,000 years across space to reach us.

Historical records suggest eruptions in 1787 and possibly even 1217, when a German monk wrote of a "wonderful sign" in the Northern Crown.

When it erupts, T CrB will glow as brightly as the North Star. No telescope needed—just clear skies and a moment of cosmic luck.

Studying the outburst’s light lets scientists peer inside the system’s anatomy—decoding the physics of thermonuclear stellar flares.

This is a true once-in-a-lifetime event. Most living humans have never seen T CrB erupt. Your chance may come in days—not decades.
Next-gen sky surveys, like the Vera Rubin Observatory, will soon catch novae like this in real time—changing how we watch the cosmos.
