On Earth, volcanic gasses that enter the atmosphere are dominated by steam because our planet's interior is so wet. The researchers found that volcanic gasses on Venus are made up of just 6 percent steam, at a maximum. From this, they inferred that Venus' interior is very dry, and the planet was never able to maintain a liquid ocean.
Jan 5, 2021 · According to recent climate modelling, for much of its history Venus had surface temperatures similar to present day Earth. It likely also had oceans, rain, perhaps snow, maybe continents and...
1 day ago · A team of astronomers has found that Venus has never been habitable, despite decades of speculation that our closest planetary neighbour was once much more like Earth than it is today. The researchers, from the University of Cambridge, studied the chemical composition of the Venusian atmosphere and inferred that its interior is too dry today for there ever to have been enough water for oceans ...
May 8, 2024 · Earth, Mars and Venus all looked pretty similar when they first formed. Today, Mars is dry, cold, and dusty; Venus has a hot, crushing atmosphere. Why did these sibling planets turn out...
1 day ago · From a distance, Venus and Earth look like siblings: it is almost identical in size and is a rocky planet like Earth. But up close, Venus is more like an evil twin: it is covered with thick clouds ...

Aug 11, 2016 · Scientists long have theorized that Venus formed out of ingredients similar to Earth’s, but followed a different evolutionary path. Measurements by NASA’s Pioneer mission to Venus in the 1980s first suggested Venus originally may have had an ocean.
