A rare and spectacular event is about to unfold in the night sky as a thermonuclear explosion on a dwarf star 3,000 light years away is set to become visible on Earth. Known as T Coronae Borealis or the Blaze star, this once-in-a-lifetime occurrence will be as bright as the north star for those in the northern hemisphere and as bright as Orion’s right foot for those in the southern hemisphere.
The Blaze star is a recurrent nova, becoming visible every 80 years after an explosion on the surface of a white dwarf that is in a binary system with a neighboring red giant. This explosion is triggered by the accumulation of hydrogen from the red giant, leading to a buildup of pressure and heat that causes the star to brighten significantly.
Although novae events have been observed before, this particular event is special as it can be studied with modern technology that was not available during previous occurrences. Scientists are excited to gather data using telescopes such as Nasa’s Fermi Gamma-ray Space Telescope, the James Webb Space Telescope, and the National Radio Astronomy Observatory’s Very Large Array in New Mexico.
Dr. Laura Driessen from the University of Sydney’s school of physics explains that the Blaze star is always variable in brightness, but it starts to get brighter about 10 years before an explosion, providing an early warning sign. This upcoming event will give researchers the opportunity to study the structure and specific processes involved in a nova explosion in great detail.
To view the Blaze star, observers are advised to find the darkest area possible, away from city lights, and use binoculars for a better view. It’s also recommended to let your eyes adjust to the dark and use a red torch covered with cellophane to preserve night vision. Additionally, there are free apps available to help locate the Corona Borealis in the night sky.
The last recorded sighting of the Blaze star was in 1946, and it is expected to become visible anytime from now until September. This event presents a unique opportunity for astronomers and stargazers to witness and study a rare celestial phenomenon that occurs only once every few decades. Be sure to mark your calendars and prepare for a breathtaking show in the night sky.
