After over a year of anticipation, the rare recurrent nova T Coronae Borealis, nicknamed the “Blaze Star,” may finally become visible to the naked eye tonight. Normally too faint to see without a telescope, this celestial event occurs roughly every 80 years, with the last eruption observed in 1946.
What Is the Blaze Star?
The Blaze Star isn’t a new star but a thermonuclear explosion in a binary star system 3,000 light-years away. The system consists of a red giant and a white dwarf. Over time, the white dwarf steals hydrogen from its larger companion, which accumulates until pressure triggers a massive explosion. This nova will briefly shine as brightly as the North Star, visible for up to a week.

Why Tonight?
In 2023, astronomers noticed the system dimming—a precursor to past eruptions. Jean Schneider of the Paris Observatory analyzed historical data and found a pattern: the time between explosions (78–80 years) is a multiple of the stars’ 228-day orbital period. This led to predictions for potential eruption dates: March 27, 2024 (tonight), November 10, 2024, or June 25, 2026. While unproven, Schneider theorizes a hidden third star might influence the timing.
How to Spot the Blaze Star
- Location: Look for the Corona Borealis constellation, a “U-shaped” curve between Hercules and Boötes. Use stargazing apps to pinpoint it.
- Brightness: It will glow at magnitude +2, matching the North Star’s brightness.
- Timing: Visible after sunset if skies are clear. Allow 20 minutes for your eyes to adjust to darkness.

Weather Considerations
The Met Office notes mixed conditions across the UK tonight. Clear skies are likelier in southeast England, while rain may obscure views in Scotland and Northern England. Check local forecasts before heading out.
A Rare Cosmic Spectacle
If the Blaze Star erupts, it’ll be a fleeting marvel—a reminder of the dynamic universe. As Schneider’s study suggests, if missed tonight, mark your calendar for November or 2026. Either way, this ancient light show, traveling 3,000 years to reach us, promises to be unforgettable.
