Blaze Star to explode tonight? Key prediction after multiple false alarms
Jean Schneider of the Paris Observatory made a key prediction about the Blaze Star last year
Will the Blaze Star finally explode tonight? Jean Schneider of the Paris Observatory made a key prediction in the Research Notes of the American Astronomical Society back in October 2024. The astronomer came to the possible dates for the explosion - March 27 and November 10 - using a combination of past eruption dates and the orbital ephemeris of the binary system.
The binary star system T Coronae Borealis (T CrB), is located 3,000 light-years from Earth and explosions have been reported every 79 years. A blast is due to happen since February 2024, but no clear date has been determined.
Schneider, too, admitted that no one can predict the nova. Astronomers say that the star explosion takes place once after T CrB's 128 orbits. The constellation has an orbital period of around 227 days, which brings them to the next date of the explosion - March 27, 2025.
Next dates
There is a chance that the star might not explode on March 27. Schneider offered two alternate dates - November 10, 2025, and June 25, 2026. The first date mentioned in his paper was August 12 last year.
T CrB is not one star
The T CrB isn't one star. It comprises a white dwarf and an ancient red giant star. The latter is 1.12 times the mass of our Sun and orbits the white dwarf, which is exerting gravitational pull on the red giant, stripping it of its hydrogen.

After the material from the giant star swirls around the white dwarf, it creates pressure and triggers a thermonuclear explosion. The first time the explosion was seen by humans was more than 800 years ago.
How to see the star?
When the T CrB goes nova, a big boom will be seen in the sky. To see the phenomenon, one can go outdoors at around 10 PM local time on Thursday in the Northern Hemisphere.
