Now, attention is once again focused on T Coronae Borealis — also known as the “Blaze Star” — after researchers identified June 25, 2026, as the statistically most likely date for its long-awaited eruption. An artist's rendering of T Coronae Borealis, also known as T CrB, a recurrent nova in the constellation Corona Borealis. It is a binary system composed of a red giant star and a white dwarf star, surrounded by an accretion disc, and has outbursts approximately every 80 years.gettyKey FactsT Coronae Borealis is a recurrent nova located around 3,000 light-years from the solar system in Corona Borealis, a crescent-shaped constellation of seven stars between the bright stars Vega and Arcturus.The star system erupts roughly every 80 years — almost the perfect definition of a once-in-a-lifetime event — with previous outbursts recorded in 1866 and 1946.Astronomers expect it to brighten from its usual 10th magnitude to around magnitude +2 or +3, making it visible to the naked eye for a few days or weeks. Its explosion will be one of the most unusual astronomical events visible without any special equipment. According to Sky & Telescope, if the nova does not occur around that date, the next most likely eruption window would be February 8, 2027. if (!window.cnxel) { window.cnxel = {}; window.cnxel.cmd = []; var iframe = document.createElement('iframe'); iframe.style.display = 'none'; iframe.onload = function() { var iframeDoc = iframe.contentWindow.document; var script = iframeDoc.createElement('script'); script.src = '//cd.elements.vi...
