Mystery of exploding stars yields to astrophysicists
Los Angeles CA (SPX) Aug 20, 2015
A longstanding mystery about the tiny stars that let loose powerful explosions known as Type Ia supernovae might finally be solved. For decades, astronomers have debated whether one white dwarf star, or two, is necessary for firing up this particular kind of supernova. The answer is not merely academic. Understanding the nitty-gritty physics and diversity of Type Ia supernovae will help illuminate our study of the evolution of galaxies and the strange cosmic force known as dark energy. "It's ... read more
