Scientists from Curtin University found a very old place in Western Australia. A big rock from space hit the ground there a long time ago.

科廷大學的科學家在西澳大利亞發現了一個非常古老的地方。很久以前，有一塊巨大的太空隕石撞擊在該地。

The scientists looked at the North Pole Dome. They studied small crystals in the rocks. These crystals show the rocks became very hot. The scientists say the space rock hit Earth 3 billion years ago.

科學家研究了北極圓頂（North Pole Dome）。他們研究了岩石中的微小晶體。這些晶體顯示岩石曾變得非常炎熱。科學家表示，該太空隕石是在 30 億年前撞擊地球的。

Some other scientists do not agree. A researcher from Harvard University says the site is younger. He thinks the hit happened 2.77 billion years ago.

其他一些科學家並不認同。一名來自哈佛大學的研究員表示，該地點的年代較新。他認為撞擊發生在 27.7 億年前。

These experts are still talking about the date. It is hard to find the exact age of very old rocks.

這些專家仍在討論日期。要找出極古老岩石的準確年齡是很困難的。

The North Pole Dome might be the oldest hole from a space rock, but scientists are still arguing about it.

北極圓頂可能是最古老的太空隕石坑，但科學家們仍在爭論。
