Cataloguing Venus: Discovering More Than 85,000 Volcanoes on Earth's Sister Planet
A new map created from radar imagery collected during Nasa’s Magellan mission in the 1990s has catalogued more than 85,000 volcanoes on Venus, 99% of which are less than 5km in diameter. The data, which is publicly available, will help scientists better understand the inner workings of the planet and where to search for evidence of recent geological activity. The researchers hope to learn more about magma availability and eruption rates on Venus, as volcanoes in the 20km- to 100km-diameter range are relatively scarce.
