Tiny pieces of glass found scattered across Australia have revealed evidence of a previously unknown giant asteroid impact. This discovery centers on a new type of tektite, a natural glass formed when ...

Scientists thought that an Australian museum’s collection of tektites came from an 800,000-year-old asteroid strike on Earth. Some of them turned out to be much older. By Katherine Kornei Every few ...

Tektites are natural glasses formed by the high-energy impact of large meteorites against Earth’s surface. Recently, a team of researchers found a new strewn field of them in the Brazilian state of ...

Researchers discovered a new field of ancient tektites in South Australia, revealing a long-forgotten asteroid impact. These 11-million-year-old glass fragments differ chemically and geographically ...

Throughout the planet, there are only a handful of known tektite strewn fields, which are large swaths of land where natural glass (tektite) was strewn about after forming from terrestrial material ...

Geologists have found glass pieces known as tektites strewn across a 900-kilometer (560-mile) strip of Brazil. The discovery indicates that around 6 million years ago, South America was struck by a ...

The chemical makeup of mineral inclusions preserved in impact glass hints at the site of a missing impact crater. Tektites are natural glass formed when debris falls back to Earth after a meteorite ...

Tektites are natural glass formed from terrestrial debris falling back to Earth after a meteorite impact. Based on their distribution and chemical composition, researchers mapped out four large strewn ...

Scattered thinly over the earth’s surface are large patches of tektites—glassy lumps up to several inches across, of mysterious and probably unearthly origin. In Britain’s Nature, American Chemist ...
