Venus: Proof of active volcanoes—at last

PHYS.ORG   19 March 2023   World  

Venus is almost the same size, mass and density as Earth. So it should be generating heat in its interior (by the decay of radioactive elements) at much the same rate as the Earth does. On Earth, one of the main ways in which this heat leaks out is via volcanic eruptions. During an average year, at least 50 volcanoes erupt.
But despite decades of looking, we've not seen clear signs of volcanic eruptions on Venus—until now. A new study by geophysicist Robert Herrick of the University of Alaska, Fairbanks, which he reported this week at the Lunar & Planetary Science Conference in Houston and published in the journal Science, has at last caught one of the planet's volcanoes in the act.
