Rare glass from 6-million-year-old meteorite strike found in Brazil — but the crater is still missing

Six black rock-like objects in different shapes.

Brazil is host to a newly found field of natural glass created from meteorite impacts, according to a new study.

The natural glass is known as a tektite, which occurs after terrestrial rocks are melted when meteorites, comets, or asteroids slam into the surface of our planet, according to Encyclopedia Britannica. (The word "tektite" is derived from Ancient Greek words that mean "melted" or "molten".)
