Helium, in turn, fused to form heavier elements, like beryllium, carbon and oxygen in a process known as nucleosynthesis.

反过来，氦在称为核过程中融形更重元素，如铍、碳和氧。

When the star explodes, the gas gets so hot and is compressed so violently by the blast that it undergoes fusion, what astronomers call explosive nucleosynthesis: literally, creating heavy elements explosively.

当恒星爆炸时，气体会变得很热，并被猛烈，从而发生聚变，天学家称之为爆炸核聚变：确切说，就是爆炸般产生重元素。
