UAF professor Robert Herrick reviewed radar imagery of the surface of Venus collected over eight months in 1991 by NASA’s Magellan spacecraft and found evidence of lava flow at a vent on Venus’s largest volcano, Maat Mons.
This computer-generated 3D model of Venus’ surface shows the summit of Maat Mons, the volcano that is exhibiting signs of activity. A new study found one of Maat Mons’ vents became enlarged and changed shape over an eight-month period in 1991, indicating an eruptive event occurred.
“Not only is it 9 kilometers high, it covers an area that is over a thousand kilometers across, so we’re looking at a very small part of a gigantic volcano,” Herrick said. “The type of analysis that resulted in this discovery, really required the ability to pan around few hundred gigabyte data sets and zoom in and out,” he said.

The Best Way to Learn About Venus Could Be With a Fleet of BalloonsInterest in the exploration of Venus has kicked up a notch lately, especially after a contested recent discovery of phosphine, a potential biosignature, in the planet’s atmosphere. Plenty of missions to Venus have been proposed, and NASA and ESA have recently funded several. However, they are mainly orbiters, trying to peer into the planet’s interior … Continue reading 'The Best Way to Learn About Venus Could Be With a Fleet of Balloons'
