The upcoming nova has generated excitement within the scientific community. Sumner Starrfield, a professor of astrophysics at Arizona State University, expressed his anticipation to AFP: “It could be today… but I hope it’s not,” he joked while working on a paper to predict what astronomers might learn from the event.

NASA predicts ‘once-in-a-lifetime’ explosion by September 2024

NASA explains that a nova results from dramatic changes in a star that cause it to release a significant amount of energy, temporarily becoming extremely bright. It was first discovered in 1866 and made a subsequent appearance in 1946.

NASA has announced that a rare stellar event, known as a nova, is expected to illuminate the night sky later this year. This celestial phenomenon, described by the space agency as a “once-in-a-lifetime” occurrence, is predicted to be visible without the need for telescopes or specialized equipment.

According to VOA News, astronomers anticipate the nova will likely occur by September 2024. The event will involve a binary star system located in the constellation Corona Borealis, approximately 3,000 light-years from Earth. This system, named T Coronae Borealis, consists of two gravitationally linked stars: a white dwarf and a red giant.

NASA explains that a nova results from dramatic changes in a star that cause it to release a significant amount of energy, temporarily becoming extremely bright. Unlike a supernova, which marks the final destruction of a star, a nova allows the white dwarf to remain active after the event.

The process leading to a nova in a binary system involves the transfer of hydrogen from the red giant to the white dwarf. Over time, this accumulation creates intense pressure and heat on the white dwarf’s surface. “This buildup can cause a thermonuclear explosion large enough to blast away the material the white dwarf had collected,” astronomers told AFP.
