Breathtaking view


You’re looking at a picture of the Vanuatu Archipelago in Australia, shrouded in vog-a word used to describe the kind of volcanic smog which is formed when gases from a volcano react with sunlight, oxygen and moisture.

The results are stunning. You can see the vog as a light blue-gray plume which arcs from the volcanic island. The other feature in the image is a band of silver-gray, running north-south, called “sunglint” – the reflection of the sun off the ocean as the image is acquired by the satellite. The image of Vanuatu Archipelago-a collection of volcanic islands about 1,100 miles northeast of Australia-was captured by NASA’s Aqua satellite earlier this month.
