A fresh analysis of radar images obtained more than three decades ago has yielded new evidence indicating Venus, Earth's planetary next-door neighbour, is currently volcanically active - a dynamic world with eruptions and lava flows.
Researchers said on Wednesday radar images taken by NASA's Magellan spacecraft showed that a volcanic vent about a mile wide on the Venusian surface expanded and changed shape over an eight-month span in 1991. The vent is situated on Maat Mons, which at about 5 miles tall is the planet's highest volcano and second-highest mountain.
The vent is located on the north side of a larger volcanic structure just off the main summit of Maat Mons. The new findings suggest there are eruptions on Venus about every few months, similar to some Earth volcanoes in places like Hawaii, the Canary Islands and Iceland, Herrick said.
