These peculiar geological structures could explain a long-standing mystery of how Venus loses its heat.
Given Venus and Earth are both rocky planets with roughly the same size and chemistry of their rocks, they should be losing their interior heat to space at a similar rate. How Earth loses its heat is well known, whereas Venus' flow process remains a mystery.from NASA, new research has taken a fresh look at how Venus cools using data from the NASA Magellan mission that spans three decades and discovered that thin parts of the planet's uppermost layer might provide an answer.
Sixty-five previously unstudied coronae that were up to a few hundred miles broad were the main focus of the study. They assessed the depth of the trenches and ridges encircling each corona to determine the thickness of the lithosphere surrounding them.

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'
