Proof that Earth is bombarded by 10 times more asteroids than previously thought


The red tape affects the use of the U.S. government's space assets that assist scientists in the study of "airbursts" like the meteor that exploded without warning over Russia in 2013. ... Monitoring continues The network, known as the International Monitoring System (IMS is managed by the Comprehensive Nuclear Test Ban Treaty Organization [CNTBTO]), has in recent years detected shock waves from a number of airbursts, which has provided additional evidence of more frequent asteroid ...

Ancient "desert glass" turns out to be from a 29-million-year-old meteorite


“Both meteorite impacts and airbursts can cause melting, however, only meteorite impacts create shock waves that form high-pressure minerals, so finding evidence of former reidite confirms it was created as the result of a meteorite impact,” added Cavosie. Researchers also warned that people should be careful of using LDG and other glasses that come from high-pressure rock deformation as evidence of airbursts. "...
