Research indicates planet’s interior is dry in blow to theories that it was previously habitable
The team of researchers studied volcanic emissions and found a ‘scarcity of water’ that reflected ‘an equally dry Venusian interior’.The team of researchers studied volcanic emissions and found a ‘scarcity of water’ that reflected ‘an equally dry Venusian interior’.With a surface hot enough to melt lead and with clouds of sulphuric acid above it, it is a planet often called Earth’s “evil twin” – similar in size, yet worlds apart.
“This doesn’t completely rule out any life. It rules out Earth-like life,” said Tereza Constantinou, first author of the research from the University of Cambridge.– has long been a hot topic among scientists. Some believe the planet was once much more like Earth but then underwent a runaway greenhouse effect. Others believe Venus has always been inhospitable.
“If you look at any photos of volcanism on Earth, you see kind of these large billowing clouds coming out. Most of that is water,” she said. However, when the team analysed the ratios of substances being replenished in the Venusian atmosphere, they found very little water was being added; in other words, volcanic eruptions were “dry”.
