Nova Event in Corona Borealis. Astronomers are eagerly awaiting the emergence of what is being described as a “new star” in the night sky, expected to grace our celestial canvas anytime between now and September, according to NASA. This anticipated celestial event promises to be a once-in-a-lifetime sight for stargazers.
Understanding Novas and Their Significance
The awaited brightening event, known as a nova, is set to occur in the Milky Way’s Corona Borealis, also referred to as the Northern Crown constellation, positioned between the Boötes and Hercules constellations. Unlike a supernova, which marks the explosive demise of a massive star, a nova refers to the sudden, brief explosion from a collapsed star, specifically a white dwarf.
Exploring T Coronae Borealis: The “Blaze Star”
T Coronae Borealis, colloquially known as the “Blaze Star,” is a binary system within the Corona Borealis constellation. This system comprises a dead white dwarf star and an aging red giant star. Red giants form when stars have depleted their hydrogen fuel for nuclear fusion and begin their dying process. In approximately 5 to 6 billion years, our sun is predicted to evolve into a red giant, expanding and likely affecting the fate of inner planets, though uncertainties persist regarding Earth’s destiny, as indicated by NASA. Every 79 years or so, T Coronae Borealis experiences an explosive event, adding to its mystique and allure among astronomers.
