… on Mars? New research suggests a volcano, not a large impact, may have formed Mars’s Eden Patera basin. The volcano is a vast circular basin on the face of the Red Planet which had previously had been classified as an impact crater. Researchers now suggest the basin may be the remains of an ancient supervolcano’s eruption. The finding is based on images and topographic data from NASA’s Mars Odyssey, Mars Global Surveyor, and Mars Reconnaissance Orbiter spacecraft and the European Space Agency’s Mars Express orbiter.
