Dust over Eastern Australia
A gigantic Outback storm swept through Australia on Sept. 23, 2009, and it was thought to be as much as 500 kilometers (310 miles) wide and 1,000 kilometers (620 miles) long. Residents experienced red skies, hail and gale-force winds in what was called Sydney's worst dust in 70 years. The storm was thought to be the result of the multiple-year drought. Here we see the storm as imaged by the MODIS on NASA’s Terra satellite.
