About 800,000 years ago, a monster space rock struck the Earth hard and fast.
大约80万年前，一块巨大的太空岩石猛烈而快速地撞击了地球。
The impact of the 1.2 mile-wide (1.9 kilometre-wide) meteorite flung debris across 10 percent of the planet's surface.
这颗1.2英里宽(1.9公里宽)的陨石的撞击将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.
科学家们在亚洲、澳大利亚和南极洲发现了这种古老的碎片，主要是被称为tektites的玻璃团块的形式。
But until now, researchers had never found the site where the meteorite hit.
但直到现在，研究人员还没有找到陨石撞击的地点。
They'd been searching unsuccessfully for more than a century.
他们已经搜索了一个多世纪都没有成功。
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“美国国家科学院院刊”(Proceedings Of The National Academy Of Sciences)上发表的一项新研究中，科学家们描述了他们认为这块巨大的岩石坠毁的地点：老挝东南部的一片火山地。
"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.
“从柬埔寨北部到老挝中部，甚至中国南部，从泰国东部到越南近海，都有很多寻找撞击地点的尝试和许多建议，”这项研究的主要作者克里·谢(Kerry Sieh)告诉CNN。
