This energy is liberated at the center of the Sun as billions upon billions of nuclei of hydrogen atoms collide with each other and fuse together to form nuclei of helium, and in doing so, release some of the energy that is stored in the nuclei of atoms.

• 数十亿计的氢原子核在太阳的核心碰撞并且聚变生成氦。 在此过程中一部分原本储存于原子核中的能量被释放出来。
