The investigation of geological features called coronae sheds light on how Venus loses internal heat and gives clues about its volcanic activity.
"While Venus doesn't have Earth-style tectonics, these regions of thin lithosphere appear to be allowing significant amounts of heat to escape, similar to areas where new tectonic plates form on Earth's seafloor."
An enhanced heat flow points to increased volcanic activity below the surface where this heat escape happens through buoyant plumes of molten rock rising to the outer layer. This points to the coronae as regions at which geological activity and volcanism are forging the appearance of Venus' surface. "What's interesting is that Venus provides a window into the past to help us better understand how Earth may have looked over 2.5 billion years ago," Smrekar said."It's in a state that is predicted to occur before a planet forms tectonic plates.", the Venus Emissivity, Radio Science, InSAR, Topography, And Spectroscopy mission. Currently set to launch later this decade, VERITAS will journey to Venus to continue the mission of Magellan.

Bizarre Geologic Activity on Venus: “Squishy” Outer Shell May Be Resurfacing the PlanetThe research uses archival NASA data to show that Venus may be losing heat from geologic activity in regions called coronae, possibly like early tectonic activity on Earth. Earth and Venus are rocky planets of about the same size and rock chemistry, so they should be losing their internal heat to

Venus’ Outer Shell is Thinner and “Squishier” Than Previously BelievedWhile Earth and Venus are approximately the same size and both lose heat at about the same rate, the internal mechanisms that drive Earth’s geologic processes differ from its neighbor. It is these Venusian geologic processes that a team of researchers led by NASA’s Jet Propulsion Laboratory (JPL) and the California Institute of Technology hope … Continue reading 'Venus’ Outer Shell is Thinner and “Squishier” Than Previously Believed'
