Gary sent in the link to https://www.dailymail.co.uk/sciencetech/article-11862699/ … Venus is volcanically active we are told – scientists have found strong evidence to say so. Perhaps. Eruptions and lava flows occur. In fact, images of a vent on Venus, taken 8 months apart, seem to show a change in shape. This, they think, may indicate lava flow. NASAs Magellan spacecraft provided the evidence.
Venus is also home to more volcanoes than occur on any other planet in the solar system, it is alleged. It is also very hot at the surface with atmospheric pressure much greater than on any other planet. Sixty five per cent of the surface appears to be composed of lava outflow plains – and has a younger surface than the other rocky planets. Simulation of geodynamic processes on Venus do not agree on the level of volcanic activity – but they do commonly seem to show that it exists. These estimates are speculative, we are told – a sort of add-on
The same story is at https://phys.org/news/2023-03-scientists-evidence-venus-volcanically.html … which is a fuller description of the research published in the journal Science on March 15th 2023 – see https://doi.org/10.1126/science.abm7735 … or https://www.science.org/doi/10.1126/science.abm7735 … Researchers suggest the vent may have been caused by a collapse of the vent’s wall, which may not be seismically related. However, on earth, vent collapses are commonly associated with volcanic activity.
The story is also at https://tallbloke.wordpress.com/2023/03/scientists-offer-evidence-that-venus-is-volcanically-active/ … wherein the first commenter denies Venus is geologically young, as famously suggested by Velikovsky. However, that is not what the researchers said. They made the point the surface of Venus was geophysically young – and showed evidence of repeated lava outflow. In other words, the surface had been changed by volcanism.
Interesting that this idea comes a couple of days after another group of researchers was thinking in terms of Venus as a watery planet – in former times.
