When a white dwarf star explodes as a supernova, it may detonate like a nuclear weapon on Earth, a new study published in the latest issue of the journal Physical Review Letters revealed.
White dwarfs are the dim, fading, Earth-size cores of dead stars that are left behind after average-size stars have exhausted their fuel and shed their outer layers. Our sun will one day become a white dwarf, as will more than 90% of the stars in our galaxy.
