New research has revealed that Mars’ most recent volcanoes weren’t formed by simple, one off eruptions as scientists previously thought. Instead, these volcanic systems evolved over millions of years, fed by complex underground magma chambers that changed and developed over time. By studying surface features and mineral signatures from orbit, researchers have pieced together a far more intricate volcanic story than anyone expected.
