科學家揭示太空稀有元素的形成機制
Scientists uncover how rare elements are made in space
你是否曾好奇你珠寶中的黃金，或是發電廠裡的鈾是從哪裡來的嗎？
Have you ever wondered where the gold in your jewelry or the uranium in our power plants comes from?
它們並非來自我們自己的太陽系，而是來自深太空中劇烈且古老的事件。
It is not from our own solar system, but from violent, ancient events in deep space.
雖然一般的恆星會融合輕元素，但它們在達到鐵（ㄊㄧㄝˇ）元素時就會停止。
While regular stars fuse light elements, they stop at iron.
創造更重的元素，即所謂的「核合成」（ㄏㄜˊㄏㄜˊㄔㄥˊ）過程，需要更多的能量。
Creating heavier elements, a process called nucleosynthesis, requires much more energy.
科學家扮演宇宙考古學家的角色，研究古老恆星的化學成分以理解這個謎團。
Scientists act as cosmic archaeologists, studying the chemistry of ancient stars to understand this mystery.
他們專注於 r-過程，也就是快速中子捕獲，這發生在如中子星合併這類毀滅性的事件中。
They focus on the r-process, or rapid neutron capture, which occurs during cataclysmic events like neutron star mergers.
當兩顆高密度恆星相撞時，它們會產生「千新星」（ㄑㄧㄢㄒㄧㄣㄒㄧㄢ），將重元素散佈到整個銀河系。
When two dense stars collide, they create a kilonova, scattering heavy elements across the galaxy.
最近，研究人員發現一些極重的元素甚至可能透過分裂（ㄈㄣㄌㄧㄝˋ）作用而分離，這有助於平衡我們今日所見的豐度模式。
More recently, researchers have discovered that some extremely heavy elements may even split through fission, helping to balance the abundance patterns we see today.
透過使用粒子加速器在地球上模擬這些條件，物理學家們終於將這些線索串聯起來。
By using particle accelerators to simulate these conditions on Earth, physicists are finally connecting the dots.
你所擁有的每一顆金原子或鉑（ㄅㄛˊ）原子，都是數十億年前一場古老且爆炸性的恆星死亡遺留下來的遺跡。
Every atom of gold or platinum you possess is a relic of an ancient, explosive star death that occurred billions of years ago.
