T Coronae Borealis, the once-in-80-years "Blaze Star", was expected to erupt in 2024—but it’s still keeping us waiting in 2025.

First recorded in 1866, the nova last erupted in 1946, and it should burst to naked-eye brightness any day now—but when?

Astronomer Gesesew Reta of S.N. Bose Centre found spectral shifts that suggest an imminent eruption, but novae remain unpredictable.

Recurrent novae, like T CrB, are extremely rare, with only about six known examples, making this an astronomical must-watch event.

T CrB rises in the eastern midnight sky, brightening Corona Borealis—so keep an eye out before dawn for a new star.
The nova happens when a red giant dumps material onto a white dwarf, triggering a runaway thermonuclear explosion.
T CrB could reach +2nd magnitude, visible to the naked eye, but it won’t be the “brightest star ever” as some headlines claim.
Expect JWST and Hubble to study this eruption, offering a rare deep-space view of a nova explosion in real time.
Look east after midnight to spot Corona Borealis. If a new star appears, it's the nova! Best seen in March–April pre-dawn skies. No telescope needed! Track updates on AAVSO & SpaceWeather.com.
