This bright star will soon die in a nuclear explosion — and could be visible in Earth's daytime skies

The star system V Sagittae, located 10,000 light-years away, features a white dwarf rapidly consuming material from its companion star at an unprecedented rate, creating sustained thermonuclear reactions that make it the galaxy's brightest supersoft X-ray source. This extreme process will likely trigger a nova explosion visible to the naked eye, followed by an even more spectacular supernova when the stars eventually collide, potentially creating a blast bright enough to see during daytime and possibly occurring as early as 2067.
