黃金與重元素在太空中是如何形成的
How gold and heavy elements are created in space
你曾經好奇過你珠寶中黃金的起源嗎？
Have you ever wondered about the origin of the gold in your jewelry?
雖然恆星以產生光和熱而聞名，但牠們面臨著一個極限：牠們只能將元素聚變至鐵為止。
While stars are famous for creating light and heat, they face a limit: they can only fuse elements up to iron.
為了創造像黃金或鉑這樣更重的貴金屬，宇宙需要不同的配方。
To create heavier, precious metals like gold or platinum, the universe needs a different recipe.
這個過程依賴中子捕獲，即原子吸收額外的中子來長成更重的元素。
This process relies on neutron capture, where atoms soak up extra neutrons to grow into heavier elements.
S-過程，即慢速中子捕獲，會在衰老的恆星中緩慢地發生。
The s-process, or slow neutron capture, occurs gently in aging stars.
然而，對於最重的元素，宇宙會轉而採用R-過程，即快速中子捕獲。
However, for the heaviest elements, the universe turns to the r-process, or rapid neutron capture.
這需要像中子星對撞這樣極端且劇烈的環境。
This requires extreme, violent environments like colliding neutron stars.
科學家曾經認為這些僅由超新星產生，如今則認識到中子星合併是重要的宇宙工廠。
Once thought to be produced solely by supernovae, scientists now recognize that neutron star mergers are major cosmic factories.
我們今天在地球上發現的黃金，實際上就是星塵，極有可能是在地球形成許久之後，由小行星帶來的。
The gold we find on Earth today is literal stardust, likely delivered to our planet by asteroids long after its formation.
每一塊黃金都是銀河系中最罕見且充滿能量之事件的見證者。
Every piece of gold is a testament to the most rare and energetic events in the galaxy.
