In a remarkable breakthrough, NASA has unveiled a new window into our cosmic history.
在一項非凡的突破中，NASA揭示了窺探我們宇宙歷史的新窗口。
By combining the unique strengths of the Hubble and James Webb Space Telescopes, astronomers have successfully observed 27 tiny, ancient objects known as Trans-Neptunian Objects (TNOs).
透過結合哈伯與詹姆斯·韋伯太空望遠鏡的獨特優勢，天文學家成功觀測了27個被稱為「海王星外天體」（TNOs）的微小古老物體。
These distant, icy bodies orbit far beyond Neptune and act as literal time capsules, preserving conditions from 4.5 billion years ago.
這些遙遠的冰冷天體運行在海王星之外，就像實實在在的時間膠囊，保存了45億年前的狀態。
Surprisingly, the study revealed fewer of these small objects than scientists had predicted, suggesting that our current theories on planet formation may need refining.
令人驚訝的是，這項研究顯示這些微小天體的數量比科學家預測的要少，這暗示我們現有的行星形成理論可能需要修正。
By comparing 'cold' TNOs, which have remained undisturbed since the solar system's birth, with 'hot' TNOs, which were pushed outward by giant planets, researchers are piecing together the mysterious era when dust and pebbles first began to coalesce into the planets we know today.
藉由比較自太陽系誕生以來未受干擾的「冷」TNO，以及被巨大行星推向外圍的「熱」TNO，研究人員正拼湊出塵埃與礫石最初開始聚合形成今日行星的神秘時代。
This discovery not only showcases the incredible synergy between our most advanced observatories but also brings us closer to understanding the fundamental building blocks of our home in space.
這一發現不僅展示了我們最先進的觀測站之間令人難以置信的協同效應，也讓我們更接近理解我們太空家園的基本構成要素。
