About this work

The northern lowlands of Mars in this location are stippled with mounds, such as those visible throughout this image. These lighter-toned circular mounds with bowl-shaped depressions are easy to spot against the darker-toned floor. Scientists think these landforms are similar to mud volcanoes that are also found here on Earth. Mud volcanoes form as gas and liquid-rich sediment interacts underground. Over time, this slurry of mud is brought to the surface and forms a rounded mound.
