Overview

• T Corona Borealis, a binary star system in the Northern Crown constellation, is expected to undergo a nova explosion on March 27, 2025, based on historical patterns and recent observations.
• The explosion, caused by a thermonuclear reaction on the white dwarf star, could increase its brightness to rival the North Star, making it visible to the naked eye.
• Previous nova events for T Corona Borealis were recorded in 1787, 1866, and 1946, establishing a roughly 80-year recurrence pattern.
• Astronomers have closely monitored the star since September 2024, noting variations suggesting an imminent explosion, though alternative dates in late 2025 and 2026 remain possibilities.
• The event offers a unique opportunity for both professional and amateur astronomers to study recurring novae and improve predictive models of stellar phenomena.
