A rare and massive binary star system located 150 light years away from Earth is on a collision course, predicted to produce an explosion 10 times brighter than the Moon. The system consists of two compact white dwarfs, each about as big as the Earth, with masses significantly higher than our sun. As they approach each other, their gravitational forces will cause one to draw material from the other’s outer layer, leading to a catastrophic thermonuclear explosion known as a type 1a supernova.
This event is expected to be a quadruple detonation, releasing an enormous amount of energy – 10 times that of the Moon’s brightness. The explosion will destroy the entire system, making it one of the most powerful cosmic events in recent history. Scientists have been monitoring the system using data from four ground-based telescopes and are eager to study its dynamics further.
