Astronomers Predict Rare T Coronae Borealis Nova Could Erupt Today
The binary star system, located 3,000 light-years away, may brighten dramatically, becoming visible to the naked eye for the first time since 1946.
- T Coronae Borealis, a binary star system in the Corona Borealis constellation, is predicted to erupt in a nova on March 27, 2025, though the timing remains uncertain.
- The nova, caused by a thermonuclear explosion on the system's white dwarf star, is expected to elevate its brightness to magnitude +2, rivaling the North Star.
- Astronomers have observed brightness variations since 2023, suggesting an imminent explosion, but previous predictions, including one in April 2024, did not materialize.
- If the nova does not occur today, alternative dates for the event are November 10, 2025, and June 25, 2026, according to researchers.
- The event, visible to the naked eye for several days and with binoculars for over a week, offers a rare opportunity for public observation and scientific study.
