Researchers have mapped out at least 85,000 volcanoes on Venus' surface, and recent findings suggest that some of them are likely active.
Less than a month ago, scientists were unsure if Venus had active volcanoes. Now, a new map reveals that there could be at least 85,000 of them covering the surface of the hellish planet.
But on March 15, researchers published a reanalysis of data collected during NASA's Magellan mission that orbited a probe around Venus between 1989 and 1994. The data revealed the first evidence of recent volcanic activity on Venus, after the researchers spotted traces of a volcanic eruption that occurred in 1991. Prior to this, on Feb.
Around 99% of the volcanoes on the map are quite small — less than 3.1 miles wide. This makes them hard to differentiate from their surroundings, which is why so many had gone unnoticed until now, researchers wrote in the paper. Many of these small volcanoes are clumped into groups, called volcanic fields, but it is unclear why this has happened.
