So at this point, the massive star is left with a carbon core, which, as you know, is the building block of life.

所以在这一点上， 这颗大质量恒星只剩下一个碳核，正如你所知， 它是生命的基石。

This carbon core continues to collapse and as a result, the temperature increases, which allows further nuclear reactions to take place, and carbon then burns into oxygen, into neon, silicon, sulphur and ultimately iron.

这个碳核继续坍塌， 结果温度升高，这使得进一步的核反应发生， 然后碳燃烧成氧气， 变成氖、硅、硫， 最后变成铁。
