Astrophiles in and around the globe are eagerly anticipating a remarkable celestial event that is expected to occur sometime between now and September. A binary star system located 3,000 light years away in the constellation Corona Borealis, known as the “northern crown,” is set to dazzle the night sky with a rare and captivating explosion. Typically too faint to be visible to the naked eye, this star system is home to two stars locked in a deadly dance that results in sporadic explosive eruptions. These explosions, occurring roughly every 80 years, emanate a bright light resembling a new star in the sky, shining as luminously as the North Star for a brief period.
The forthcoming explosion is anticipated to be the third witnessed event of its kind since its initial discovery by the Irish polymath John Birmingham in 1866 and a subsequent reappearance in 1946. Renowned astronomer Sumner Starrfield of Arizona State University, who has dedicated decades to studying this binary system, is enthusiastic about the imminent celestial outburst. Starrfield, currently racing to finalize a scientific study predicting the outcomes of the recurring nova, remains optimistic about what astronomers worldwide will uncover during this extraordinary event in the coming months.
In the intricate binary star system of T Coronae Borealis, a red giant star in its dying stages orbits a white dwarf, the residual core of a dead star. This cosmic pairing boasts a significant size contrast, with the white dwarf taking 227 days to encircle its massive companion. Material expelled by the red giant accumulates near the white dwarf’s surface until a critical mass – roughly equivalent to that of Earth – triggers a thermonuclear reaction, culminating in a massive explosion that spikes the temperature by millions of degrees. Retired German astronomer Joachim Krautter, an expert on novae phenomena, highlights the significance of the forthcoming event and the potential insights the James Webb Space Telescope could offer.
While cutting-edge technology like the James Webb Space Telescope is poised to observe the celestial spectacle, Krautter stresses that the event can be observed with the naked eye by gazing towards the Corona Borealis constellation. As sky gazers await this striking cosmic display, the anticipation for a rare total solar eclipse scheduled on Monday across the United States only heightens the excitement for the forthcoming astronomic events on the horizon.
