Australian ‘bush glass’ bears the fingerprints of a cosmic collision with an iron meteorite

A zap with a laser in the lab confirmed the extraterrestrial origins of enigmatic lumps of glass found in the Northern Territory.

The Conversation

lutruwita/Tasmania is home to some amazing geology, and being a space nerd it’s easy to have a favourite rock here: Darwin Glass. This tektite was formed by a melted mix of terrestrial and extra-terrestrial materials, as a result of the heat and pressure of a large meteorite impact.

It’s part of the unique and beautiful landscape of the west coast, formed an important tool-making material for the Tasmanian Aboriginal peoples of the region, and requires a treacherous hike into dense snake-filled rainforest—that has long gone undisturbed—to acquire.

Today, some arrived from one of the only retailers able to sell the material in Tas. It is intended to become part of an exhibit on the geological record at our planned space-themed community science centre 🪨☄️💎
