Smoke from deadly bush fires that have devastated Australia has now spread halfway across the world, darkening skies in Argentina and beyond.
As Sydney and Canberra on Wednesday faced another day of toxic haze shrouding the skyline, U.S. weather satellite captured the smoke crossing South America and spreading out over Buenos Aires before it drifted into the Atlantic Ocean -- some 7,328 miles (11,793 kilometers) east of Sydney -- according to the National Oceanic and Atmospheric Administration.
