Binary Stars Headed for Supernova Explosion | JQJO

Astronomers have discovered a binary star system, 150 light-years from Earth, containing two white dwarfs destined to collide and explode as a Type 1a supernova. This is the first confirmed such system in our galaxy, supporting theories about Type 1a supernova origins. The explosion, predicted in 23 billion years, will be ten times brighter than the moon, providing valuable insight into stellar evolution. The system's combined mass is 1.56 times that of our sun, making it the heaviest double white dwarf system ever found.
