Astronomers predict that the star T Coronae Borealis will suddenly flash into brilliance, providing a rare treat for observers in March 2025 or later. Located 3,000 light-years from Earth in the Corona Borealis constellation, the binary star system is expected to be visible as bright as the North Star.
T Coronae Borealis is a white dwarf and red giant that accumulates material over time, leading to an eventual thermonuclear explosion. This phenomenon causes a massive increase in brightness, making the star briefly visible from Earth before fading back into obscurity. The predicted event has been closely tracked by astronomers, who have observed a significant drop in brightness early in 2023.
According to SETI Institute astronomer Franck Marchis, “Since September, we have been observing brightness variations, indicating that the long-sought explosion is imminent.” A recent study predicts that T Coronae Borealis might blow up on March 27, November 10, 2025, or June 25, 2026.
For those interested in witnessing this event, the Corona Borealis constellation will be most visible from the Northern Hemisphere. To find T Coronae Borealis, locate Arcturus and Vega, two bright stars in the east and northeast, respectively. Glance about halfway between Arcturus and the Hercules Cluster (M13) to spot T Coronae Borealis.
The explosion is expected to be brief, lasting a couple of days before fading slowly over the ensuing weeks. With telescopes and observatories around the globe in anticipation, this celestial event promises to be a spectacular display for scientists and astronomers alike.
