A single grain of stardust, extracted from a meteorite that fell in Victoria, Australia in 1969, has been dated to approximately 7 billion years old — more than 2 billion years older than our Sun. Formed in the dying atmosphere of a long-vanished star, this microscopic fragment drifted through the cosmos before becoming embedded in the Murchison meteorite, arriving at last in human hands. It is among the oldest solid matter ever analyzed, and it carries within its crystalline structure a record of how the universe forged the heavy elements that would eventually become planets, oceans, and livi
