Massive asteroid impact 6.3 million years ago left giant glass field in Brazil

​For the first time ever, scientists have uncovered a vast field of tektites in Brazil — mysterious glassy fragments forged when a powerful extraterrestrial object slammed into Earth about 6.3 million years ago. Named “geraisites” after Minas Gerais, where they were first found, these dark, aerodynamic droplets of natural glass stretch across more than 900 kilometers and may mark one of South America’s most significant ancient impact events.
