This pair of dancing stars will one day collide and explode

The star system is called “Apep” after the Egyptian god of chaos with the same name. (European Southern Observatory/) About 8,000 light-years from Earth, two stars dance. One of them takes the lead and spins aggressively around the other, with so much energy that it sucks away matter from its partner, forcing it to reveal […]
