Here on Earth, we pay quite a lot of attention to the sun.
在地球上，我们非常关注太阳。
It’s visible to us, after all, and central to our lives.
毕竟，它对我们来说是可见的，是我们生活的中心。
But it is only one of the billions of stars in our galaxy, the Milky Way.
但它只是银河系数十亿颗恒星中的一颗。
It’s also quite small compared to other stars – most are at least eight times more massive.
与其他恒星相比，它也相当小-大多数恒星的质量至少是其他恒星的八倍。
These massive stars influence the structure, shape and chemical content of a galaxy.
这些大质量恒星影响着星系的结构、形状和化学成分。
And when they have exhausted their hydrogen gas fuel and die, they do so in an explosive event called a supernova.
当它们耗尽氢气燃料并死亡时，它们就会在一次被称为超新星的爆炸事件中死亡。
This explosion is sometimes so strong that it triggers the formation of new stars out of materials in the dead star’s surroundings.
这种爆炸有时是如此强烈，以至于它会在死星周围的材料中触发新恒星的形成。
But there’s an important gap in our knowledge: astronomers don’t yet fully understand how those original massive stars themselves are initially formed.
但是在我们的知识中有一个重要的空白：天文学家还没有完全理解那些原始的大质量恒星本身最初是如何形成的。
So far, observations have only yielded some pieces of the puzzle.
到目前为止，观察只得出了这个谜题的一部分。
This is because nearly all the known massive stars in our galaxy are located very far away from our solar system.
这是因为我们银河系中几乎所有已知的大质量恒星都位于离太阳系很远的地方。
They also form in close proximity to other massive stars, making it difficult to study the environment where they take shape.
它们也是在与其他大质量恒星非常接近的地方形成的，这使得研究它们形成的环境变得困难。
