T Coronae Borealis, also called the Blaze Star, is 3,000 light years away. It is going to burst forth with great brilliance, astronomers say. When it does, it will shine as brightly as the North Star, Polaris. Only every 80 years is this rare phenomenon seen.

The star could appear on any evening tonight, experts say. Or it could take a few weeks. The glow will persist for a week or so after it explodes.
