A rare nova explosion from the binary star system T Coronae Borealis (T CrB), located approximately 3,000 light years from Earth, is expected to occur later this year. This event, which only happens about once a century, will be visible for an entire week. The explosion occurs when a white dwarf star and a red giant star come too close to each other, causing the red giant’s surface temperature to spike from around 4,000-5,800 degrees Fahrenheit to a much hotter 360,000 degrees Fahrenheit. This results in a massive explosion, releasing energy up to 100,000 times greater than the annual output from our Sun.
Unlike supernovae, novas like this do not destroy the star system but rather lead to a temporary increase in brightness. This event, anticipated between now and September, will illuminate the Corona Borealis constellation, providing a captivating celestial display.
