Here on Earth, we pay quite a lot of attention to the sun.

在地球上，我們非常關注太陽。

It's visible to us, after all, and central to our lives.

畢竟，它對我們來說是可見的，是我們生活的中心。

But it is only one of the billions of stars in our galaxy, the Milky Way.

但它只是銀河系數十億顆恆星中的一顆。

It's also quite small compared to other stars – most are at least eight times more massive.

與其他恆星相比，它也相當小-大多數恆星的品質至少是其他恆星的八倍。

These massive stars influence the structure, shape and chemical content of a galaxy.

這些大品質恆星影響著星系的結構、形狀和化學成分。

And when they have exhausted their hydrogen gas fuel and die, they do so in an explosive event called a supernova.

當它們耗盡氫氣燃料並死亡時，它們就會在一次被稱為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.

這種爆炸有時是如此強烈，以至於它會在死星周圍的材料中觸發新恆星的形成。

But there's an important gap in our knowledge: astronomers don't yet fully understand how those original massive stars themselves are initially formed.

但是在我們的知識中有一個重要的空白：天文學家還沒有完全理解那些原始的大品質恆星本身最初是如何形成的。

So far, observations have only yielded some pieces of the puzzle.

到目前為止，觀察只得出了這個謎題的一部分。

This is because nearly all the known massive stars in our galaxy are located very far away from our solar system.

這是因為我們銀河系中幾乎所有已知的大品質恆星都位於離太陽系很遠的地方。

They also form in close proximity to other massive stars, making it difficult to study the environment where they take shape.

它們也是在與其他大品質恆星非常接近的地方形成的，這使得研究它們形成的環境變得困難。
