With its thick, cloudy atmosphere, Venus has long held mysteries about its surface. It was only in the late 20th century that astronomers had detailed observations of the Venusian landscape, with the Russian Venera landers in the 1970s and 1980s and later the 1990 Magellan mission, which made high-resolution radar maps of the surface. There are many things we still don’t know, but one thing we do know is that the surface of Venus is young. And a new study in Nature Astronomy may know why.
