Astronomers said on Wednesday that they haddiscovered a lost generation of monster stars thatushered light into the universe after the Big Bangand jump-started the creation of the elementsneeded for planets and life before disappearingforever.

天文学家在周三表示，他们发现了失踪的一代巨型恒星，是它们在宇宙大爆炸之后将光照入宇宙，并在永远消失之前，瞬间启动了星球及生命所需要的所有元素的创造。

Modern-day stars like our sun have a healthy mix ofheavy elements, known as metals, but in theaftermath of the Big Bang only hydrogen, helium and small traces of lithium were available tomake the first stars.

太阳等现代恒星拥有大量重元素，也就是金属元素，但在宇宙大爆炸之后，构成第一代恒星的元素只有氢、氦和少量锂。

 

 

Such stars could have been hundreds or thousands of times as massive as the sun, accordingto calculations, burning brightly and dying quickly, only 200 million years after the universebegan. Their explosions would have spewed into space the elements that started the chain ofthermonuclear reactions by which subsequent generations of stars have gradually enriched thecosmos with elements like oxygen, carbon and iron.

根据计算，此类恒星的质量可能是太阳质量的数百或数千倍，这些形成于宇宙大爆炸后2亿年的恒星猛烈燃烧，迅速消失。它们的爆炸应该向太空喷射了开启一系列热核反应的元素，后续的几代恒星通过热核反应逐渐为宇宙增添氧、碳、铁等元素。
