VOLCANIC SUNSET ALERT: A plume of sulfur dioxide from Indonesia's deadly Mount Merapi volcano is swirling through the upper atmosphere over western Australia. This 7-day movie from the Global Ozone Monitoring Experiment-2 (GOME-2) onboard Europe's MetOp satellite shows the plume in motion, and it could soon swirl across the entire continent. Sky watchers in Australia should be alert for volcanic sunsets.
