T Coronae Borealis, also known as the “Blaze Star,” is a recurrent nova that is expected to erupt in the coming months, potentially any time now. This eruption, a once-in-a-lifetime event for most people, will cause the star to brighten significantly, making it visible to the naked eye. The last time T Coronae Borealis erupted was in 1946.
Here’s what you should know about this upcoming celestial event:
What is a nova?A nova is a sudden, dramatic brightening of a star caused by a thermonuclear explosion on the surface of a white dwarf star in a binary system.
Why is T Coronae Borealis special?It’s a recurrent nova, meaning it has erupted before and is expected to do so again.The cycle repeats roughly every 80 years, making this a relatively rare event.
What can you expect to see?When T Coronae Borealis erupts, it will appear as a new, bright star in the constellation Corona Borealis, potentially as bright as the North Star, according to some reports.
When will it happen?Predictions have varied, but some astronomers suggest it could occur anytime between now and the end of 2025.
