Explosion on a white dwarf observed

When stars like our Sun use up all their fuel, they shrink to form white dwarfs. Sometimes such dead stars flare back to life in a super hot explosion and produce a fireball of X-ray radiation. A research team has now been able to observe such an explosion of X-ray light for the very first time. https://www.sciencedaily.com/releases/2022/05/220512092655.htm
