Underwater volcano In January, researchers reported the first detailed investigation of the underwater volcano that produced the largest deep-ocean eruption in history. This high-resolution visualization of the Havre volcano, the top of which sits 650 metres below sea level near New Zealand, was created using data collected by autonomous underwater vehicles.
Antarctic light trick This image might look like vintage snap, but US photographer Christopher Michel captured it on a recent expedition to Antarctica. The central halo and three bright spots are the result of an optical phenomenon called a sun dog — or parhelion — which occurs when ice crystals in the atmosphere refract sunlight.
Rarely seen remains Spain began experiencing its worst drought in decades last year, as dry conditions, wildfires and crop deaths wrought havoc, and reservoirs hit historic lows. In this image, taken on 11 January at a reservoir in Vilanova de Sau, Catalonia, the usually submerged remains of an eleventh-century church are exposed by low water levels.
