Scientists used lasers to mimic stellar core processes of nucleosynthesis.

们利用激光模拟了恒星核心的核聚过程。

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

反过来，氦在称为核合的过程中融合形更重的元素，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，气体会热，并被猛烈地压缩，从而发生聚，天文称之为爆炸核聚：确切地说，就是爆炸般地产生重元素。
