One of the most famous meteorite impact sites is the Barringer crater in Arizona. 50,000 years ago, a 300,000 ton, 50 metre in diameter lump of iron and nickel entered the Earth's atmosphere and made this crater, and it should remind us that our environment doesn't just stop at the top of our atmosphere.
Hai 50.000 anos, unha masa de 300.000 toneladas e 50m. de diámetro, feito de ferro e níquel, entrou na atmosfera da Terra e fixo este cráter, e deberíanos lembrar que o noso contorno non remata na parte superior da nosa atmosfera,
