This hot, acidic neighbor with its surface veiled in thick clouds hasn't benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.
, and I’m fascinated by how other worlds came to be. I’m particularly interested in Venus, because it offers us a glimpse of a world that once might not have been so different from our own.
The surface of Venus as seen in these reprocessed perspective image panoramas from the Soviet Venera 13 lander.The current scientific view of Venus holds that, at some point in the past, the planet had much more water than its bone-dry atmosphere suggests today . But as the Sun grew hotter and brighter , surface temperatures rose on Venus, eventually vaporizing any oceans and seas.condition from which it couldn’t recover. Whether Earth-style plate tectonics ever operated on Venus is unknown. Water is critical for plate tectonics to operate, and a runaway greenhouse effect would effectively shut down that process had it operated there.
But the ending of plate tectonics wouldn’t have spelled the end of geological activity: The planet’s considerable internal heat continued to produce magma, which poured out as voluminous lava flows and resurfaced most of the planet. Indeed, the average surface age of Venus is around 700 million years – very old, certainly, but much younger than the multi-billion-year-old surfaces of Mars, Mercury or the Moon.
