This week’s featured image may appear to be a painted landscape, but the picture is in fact a photo, taken ten years ago by Victoria Arcenegui, an associate professor at Miguel Hernández University in Spain, during a controlled forest fire in northern Portugal. The blaze is actually hot enough to distort the image, making some of the flames appear as brush strokes, beautifully blurring together th ...[Read More]

Dust devils are like miniature tornadoes, they form when a pocket of hot air near the surface moves fast upward and meets cooler air above it. As the air rapidly rises, the column of hot air is stretched vertically, thereby moving mass closer to the axis of rotation, which causes intensification of the spinning effect by conservation of angular momentum. In the Atacama Desert [in Chile] they are r ...[Read More]
