As the planets congealed, gravitational forces and particle collisions created the high temperatures necessary to melt metals floating around in space, and minerals began their diversification.
科学家近日在距离地球3000光年的地方发现了一对衰老的双星。 据天文学家所言，它们陷入了一支“死亡舞蹈”——这支舞蹈注定会以两者的碰撞而告终，而在碰撞的过程中可能会形成一颗超新星。
A pair of aging stars discovered 3,000 light-years away is locked in a "dance" of death—a union that will end in their collision and a possible supernova, astronomers say.
