The wildfires ravaging parts of Australia can be seen from space in new satellite images released by NASA.

Australia's capital, Canberra, was enveloped in a smoky haze Sunday and air quality at midday was measured at 10 times the usual hazardous limit. The devastating fires have killed at least 24 people in Australia and destroyed almost 2,000 homes.

The early and devastating start to Australia’s summer wildfires, fed by drought and the country's hottest and driest year on record, has also been catastrophic for the country's wildlife, likely killing nearly 500 million birds, reptiles and mammals in New South Wales alone, Sydney University ecologist Chris Dickman told the Sydney Morning Herald. Frogs, bats and insects are excluded from his estimate, making the toll on animals much greater.

Thousands of firefighters continued to fight the flames that have burned millions of acres in New South Wales, Victoria and South Australia, an area twice the size of Maryland.

On Sunday, cooler temperatures and lighter winds brought some relief to threatened communities, a day after thousands were forced to escape as flames reached the suburban fringes of Sydney.

Thousands of firefighters fought to contain the blazes, but many fires continued to burn out of control, threatening to wipe out rural townships and causing almost incalculable damage to property and wildlife.
