Scientists expect that in 2025, it will be possible to observe the explosion of a new star T Coronae Nordi with the naked eye. This phenomenon occurs about once every 80 years, and the last recorded outbreak occurred in 1946.
T Coronae Nordis is a binary star system located about 2000 light-years from Earth in the constellation Corona Nordis. It consists of a red giant and a white dwarf. The white dwarf gravitationally pulls in matter from the giant, and when it accumulates too much, it undergoes a thermonuclear explosion known as a nova.
Astronomers previously predicted that the explosion would occur in 2024, but it did not happen. According to new predictions, it could happen between March and November 2025. Observations show changes in the brightness of T Coronae Nordi, which indicates the active accumulation of matter on the surface of the white dwarf.
Normally, this star has a magnitude of +10, making it invisible to the naked eye. But during an explosion, its brightness can increase to +2, allowing it to be seen even without a telescope or binoculars. However, scientists warn that, despite its spectacular appearance, it will not become the brightest star in the night sky.
The phenomenon will last only a few days, after which the star will gradually fade and return to its normal state until the next explosion in 80 years. So this is a rare chance for amateur astronomers to observe an event that only happens once in a human lifetime.
