text: Astronomers are facinated by Venus beacause the believe "it may well once have been the most Earth-like planet in our solar system" meaning a similar discussion about Mars. They believe that Venus, long ago, "was covered largely with oceans and could have supported various forms of life" demostration it could be an interesting visit to Venus and if the statements or beliefs are true, Sciencetist might find an answer why Venus doesn't support life or the bodies of oceans dissapear if it did have those features in the first place.
