Venus may have hosted life, researchers say
Today it’s an inferno, but scientists suggest billions of years ago the planet was cool enough to have liquid water. Richard A Lovett reports.
The planet Venus may once have been hospitable to life, scientists say — possibly even more so than the early Earth.
Furthermore, this may have occurred even though Venus never had plate tectonics, the process by which the Earth constantly recycles its crust by bringing fresh material to the surface via volcanoes, while subducting old rock back into the interior in places such as deep-sea trenches. It’s a process that produces damaging earthquakes and volcanoes, but also helps buffer our atmosphere’s level of carbon dioxide, thereby keeping our surface temperature in the right range for liquid water.
