Astronomers have discovered three "cosmic Methusalems" from the earliest years of the universe. These unusual stars are about 13 billion years old and experts assign them to the first generations of stars after the "dark ages." The chemical qualities of these extremely rare stellar bodies enable new insights into the events that must have led to the origins of the stars. The first stars have been assumed to be high-mass and to shine especially brightly. However, the latest observations point to hitherto unknown phenomena in the young universe, allowing for the emergence of much smaller stars.
