From Almanac:
Alert! The new star we’ve been talking about is about to explode. Experts estimate the time for the nova eruption is close to now. Get ready to see a new star in the night sky. According to NASA, it’s a rare “once-in-a-lifetime” event. Bob Berman has the details.
The impending “new star in the sky” will emerge from a binary star system (i.e., two stars or Suns that orbit each other). Officially named “T Coronae Borealis” or T CrB (pronounced “tee-core-bore”), the media is also calling it “Blaze Star.” Why? It will soon undergo a violent outburst and blaze in the night skies as a new star within the constellation Corona Borealis.
