CINCINNATI, OHIO – Following the recent celestial spectacle of a total solar eclipse, astronomy enthusiasts now have another extraordinary space event to anticipate. Astronomers have announced that a rare nova explosion in the binary system T Coronae Borealis (T CrB), located approximately 3,000 light years away, will be visible during a unique cosmic event set to occur later in 2024.
This rare nova explosion in the T CrB system is a once-in-a-century event that is expected to be visible for an entire week. NASA scientists believe that the event could happen anytime between now and September, with more accurate timing to be provided as the event draws closer. The phenomenon occurs when a collapsed white dwarf star and a red giant star come into close proximity, causing a dramatic increase in the red giant’s surface temperature to around 360,000 degrees Fahrenheit.
The significant increase in temperature prompts the red giant star to expel its outer layers onto the white dwarf, resulting in a massive explosion equivalent to the energy released by a nuclear bomb. This explosion, which is about 100,000 times greater than the Sun’s annual energy output, does not destroy the star like a supernova would. In fact, T CrB and its two stars have experienced eruptions for years, with the most notable ones recorded in 1946 and 1866.
One remarkable aspect of this event is the rapid cycle in which it occurs, completing in just one week. The brightness of the peak event will be visible to the naked eye on Earth for a few days, extending to over a week when observed using binoculars or a telescope. Given that the last recorded explosion was in 1946, astronomers speculate that the cycle operates on a roughly 79-year interval, predicting the next explosion in 2103.
To catch a glimpse of this cosmic spectacle, stargazers are advised to search within the Corona Borealis constellation, also known as the Northern Crown, located near Bootes and Hercules. This upcoming event presents a rare opportunity for enthusiasts to witness a celestial display that occurs once in a lifetime, offering a glimpse into the wondrous phenomena of the universe.
