It's been more than 20 years since scientists got a good look at the surface of Venus, but revisiting old data still has plenty to offer. "We just don't have the tools we need to understand the planet," Paul Byrne, a planetary geologist at North Carolina State University who is leading the research, told Newsweek. "It is a criminally underexplored world." The last spacecraft to send back information about the surface of Venus, which requires expensive radar gear that can see through the planet's deadly atmosphere, ended its work in 1994. By looking at the whole surface, rather than zooming in on tiny portions, they realized that those marks isolated small chunks of Venus's surface—in a way that looked eerily similar to the scientists, since Earth also displays some small chunks of crust surrounded by similar signs of wear and tear. read more Disclaimer: Chances are that this post was requested by an advertiser.
