Phosphine on Venus may have been explosive volcanoes

When phosphine was discovered in the atmosphere of Venus last Fall, the internet nearly exploded with speculation that the gas might have been produced by alien microbes, but such an inhospitable planet is unlikely to have life (at least as we know it) crawling anywhere near it. The surface alone is hot enough to melt lead at a scorching 847 degrees Fahrenheit. But exploding volcanoes? “It s unexpected because under the usual conditions on Venus with low water and volatile contents (such as CO2). Usually, volcanic eruptions are not explosive, Truong tells SYFY WIRE. “Lava would stay mostly on the surface like it does on Earth. If explosive volcanism occurs, it would have to source directly from the mantle where primordial water would have been concentrated.”
