Planetary scientists scouring decades-old data from NASA's Magellan spacecraft have found signs of lava flows coming from two volcanoes on Venus that erupted in the early 1990s. That was when Magellan orbited the hellish world overhead.scientists have identified direct geological evidence of recent volcanic activity on Venus, suggesting the planet could be as geologically active asVenus and Earth are nearly the same size and were showered with equal amounts of water billions of years ago.
Evidence for the newfound lava flows is rooted in radio waves beamed at Venus via Magellan's radar. These waves zipped through the planet's thick, toxicbefore bouncing off the world's surface and returning back to the spacecraft. These reflections, known as backscatter, can ferry information about a planet's rocky surface.
