The popular press is know for overblown hype, but I found this story on NASA too.
Sometime between now and September, scientists expect a nova explosion in Corona Borealis. The constellation is also called the Northern Crown – sorry, those of you down under.
This is a rare repeating nova:
The first recorded sighting of the T CrB nova was more than 800 years ago, in autumn 1217, when a man named Burchard, abbot of Ursberg, Germany, noted his observance of “a faint star that for a time shone with great light.”
The T CrB nova was last seen in 1946. Its behavior over the past decade appears strikingly similar to observed behavior in a similar time frame leading up to the 1946 eruption. If the pattern continues, some researchers say, the nova event could occur by September 2024.
The outburst will be brief. Once it erupts, it will be visible to the naked eye for a little less than a week – but it will be quite a sight to see. NASA
I’ve seen my share of hyped comets that never got past the fuzzy blob stage, and the dimming of Betelgeuse that didn’t become a supernova, but history foreshadows T CrB’s possible explosion. I’ll be watching along with lots of astronomers, both amateur and professional.
You’ll find plenty of images online to help you locate the Northern Crown. Go out tonight, or as soon as you have a clear night, and get oriented so you’re ready for the big event. Below are two pages from my own copy of H. A. Rey’s book “The Stars.” Written with kids in mind, it’s still the best book for anyone who wants to learn the constellations. The World-Wide edition covers both hemispheres!
Most sources tell you to locate Hercules first. The four stars called the Keystone are the easiest for me to find. But you may want to start at the Big Dipper. The Dipper’s handle points (with a bit of a curve) toward one of the brightest stars in the Northern Hemisphere. The Northern Crown is nearby, a compact and usually not-too-impressive constellation.
If T CrB goes nova, you’ll find it easily enough. Even if the star doesn’t put on a show, enjoy the night sky.

I initially rolled my eyes when I heard about this. The story does sound like another case of popular press hype. But I’ve now heard about it from a few trustworthy science sources, so I’m starting to actually get excited.
Planetary Radio (a podcast I listen to) noted that there’s a chance we might have to wait until early 2025. They also said there’s a slim chance the star won’t go nova at all, which would be disappointing, of course, but it would also be scientifically fascinating.

Hercules is overhead early in the night now, drifting closer to the sun as sunset as the summer proceeds. It would be my luck for the star to go nova when it’s too close to the sun to be viewed… like, maybe, September would be a bummer. These cosmic events simply don’t get my approval in advance.
