Yarrabubba is a pastoral lease in the Mid West of Western Australia, a spread of red dirt and saltbush where cattle now graze and sheep once did, ringed by windmills and wells. Drive across it and you would see only the outback - vast, flat, ordinary. But beneath this quiet ground lies the eroded remnant of the oldest precisely dated meteorite impact on Earth - or at least it was, until a rival candidate emerged. About 2.229 billion years ago, a rock from space slammed into this corner of the ancient Yilgarn craton with force enough to leave a crater tens of kilometres wide. The rim has long since worn flat. The scar, though, runs deeper than any plough, and the date it carries rewrote the timeline of catastrophe on our planet.

Using uranium-lead measurements on tiny crystals of zircon and monazite - minerals that the heat and shock of the collision had reset like a stopwatch - they fixed the age ...

Near the centre of the structure stands Barlangi Rock, an outcrop of a strange rock called granophyre that geologists read as impact-generated melt - stone that was liquefied by the collision and then froze again as ro...

The impact landed just as Earth was emerging from one of its "Snowball" episodes, when ice sheets are thought to have stretched across much of the planet. The Curtin researchers proposed a provocative idea: a strike of this size ...

The station was advertised for sale in 1906, then covering 294,000 acres and carrying just a hundred head of cattle. The Nairn brothers, pastoralists from Carnamah, bought it in 1908 and turned to sheep, producing wo...
