Clouds from Australia's extreme fires can be seen from space

The sheer size and scale of the fires raging in Australia can perhaps best be seen from space.

Details: Astronauts on the International Space Station caught sight of smoke from the historic fires raging in Australia earlier this month.

• This season's bushfires in Australia have been far worse than usual, with severe drought and higher-than-normal heat fueling the flames.
