About 800,000 years ago, a monster space rock struck the Earth hard and fast.
大約80萬年前，一塊巨大的太空岩石猛烈而快速地撞擊了地球。
The impact of the 1.2 mile-wide (1.9 kilometre-wide) meteorite flung debris across 10 percent of the planet's surface.
這顆1.2英里寬(1.9公里寬)的隕石的撞擊將碎片撒向地球表面的10%。
Scientists have found this ancient debris, mostly in the form of glass blobs known as tektites, in Asia, Australia, and Antarctica.
科學家們在亞洲、澳大利亞和南極洲發現了這種古老的碎片，主要是被稱為tektites的玻璃團塊的形式。
But until now, researchers had never found the site where the meteorite hit.
但直到現在，研究人員還沒有找到隕石撞擊的地點。
They'd been searching unsuccessfully for more than a century.
他們已經搜索了一個多世紀都沒有成功。
In a new study published in the journal Proceedings of the National Academy of Sciences, scientists describe the location where they think this massive rock crashed: a volcanic field in southeastern Laos.
在“美國國家科學院院刊”(Proceedings Of The National Academy Of Sciences)上發表的一項新研究中，科學家們描述了他們認為這塊巨大的岩石墜毀的地點：老撾東南部的一片火山地。
"There have been many, many attempts to find the impact site and many suggestions, ranging from northern Cambodia, to central Laos, and even southern China, and from eastern Thailand to offshore Vietnam," Kerry Sieh, the lead author of the study, told CNN.
“從柬埔寨北部到老撾中部，甚至中國南部，從泰國東部到越南近海，都有很多尋找撞擊地點的嘗試和許多建議，”這項研究的主要作者克里·謝(Kerry Sieh)告訴CNN。
