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 ...
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 ...
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 ...
A new study reveals a previously unknown meteorite impact that took place in northeastern Brazil some 6.3 million years ago. An international team of scientists found a 900-kilometer-long "strewn ...
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 ...
