Prospector Finds 800,000-Year-Old Space Glass in Outback

Jim Miles was searching for gold in the remote Australian outback when something black on the ground caught his eye. The object turned out to be an 800,000-year-old australite, a rare piece of molten glass flung into space by a meteorite impact and returned to Earth.

Miles was prospecting about 150 kilometers north of Kalgoorlie when he made the find. "I've been dying to find one for ages and finally got one," he said.

Australites form when a meteorite crashes into Earth with such force that it sends molten debris soaring into the atmosphere. The material cools and hardens in space before falling back down as glass objects shaped like the heat shields from Apollo spacecraft.

These cosmic souvenirs are found across a vast area stretching from Antarctica to Southeast Asia, scattered across the Indian and Pacific Oceans. Yet despite their wide distribution, scientists still don't know where the original impact happened.

Planetary scientist Aaron Cavosie at Curtin University received Miles' discovery with excitement. "Eight hundred thousand years is not that long ago, geologically. That's kind of like last night," he explained.

Miles donated his find to the Space Science and Technology Centre in Perth, where Cavosie will study it. The generous gesture came with perfect timing.

Why This Inspires

On the same day Miles contacted the university, a PhD student walked into Cavosie's office with another australite she'd found on the Nullarbor. Two unrelated people bringing in rare cosmic glass on the same day struck Cavosie as "pretty bloody astronomical."

The researcher typically hears about australite discoveries only once every year or two. More finds like Miles' could help scientists finally pinpoint where the ancient meteorite struck Earth, solving a mystery that has puzzled researchers for generations.

What started as a routine day of gold prospecting turned into a contribution to space science, proving that sometimes the most exciting discoveries happen when we're looking for something else entirely.
