Phoenix, Arizona – Amateur astronomers around the world will have a unique opportunity sometime between now and September to witness a rare explosion in the night sky, originating 3,000 light years away from Earth. This extraordinary event will occur in the binary star system located in the constellation Corona Borealis, also known as the “northern crown,” which is typically too faint to be visible to the naked eye.
Experts predict that once every 80 years or so, interactions between the two stars in this system, a red giant and a white dwarf, result in a powerful nuclear explosion. The resulting blast of light travels across space, creating the appearance of a new star as bright as the North Star in the night sky for a fleeting moment. This phenomenon has been observed by humans only a handful of times, with the first sighting recorded in 1866 by Irish polymath John Birmingham.
Astronomer Sumner Starrfield from Arizona State University, who has been studying the system, known as T Coronae Borealis or “Blaze Star,” for decades, eagerly anticipates the upcoming explosion. Starrfield is currently finalizing a scientific paper to predict the outcome of this event, showcasing the valuable insights astronomers can gain whenever the nova reappears in the sky.
Recurring novas like the one observed in this binary star system are rare, occurring roughly once every 80 years due to the peculiar relationship between the two stars. In this case, the red giant star has expanded and released matter that collects near the white dwarf star, eventually leading to a massive explosion when a critical mass is reached. While this event typically occurs on a timescale of human lifetimes, the upcoming explosion has astronomers and sky gazers eagerly awaiting its occurrence.
Experts like retired German astronomer Joachim Krautter emphasize that even though advanced telescopes like the James Webb Space Telescope will be trained on this event, amateur astronomers can witness this celestial spectacle simply by looking towards the constellation Corona Borealis. As sky gazers gear up for the upcoming total solar eclipse, this explosive event in the night sky promises to be a once-in-a-lifetime opportunity for stargazers and astronomers alike.
