a new visualization of Earth looks nothing like the Blue Marble seen from space. NASA has released a new geoid model showing the shape of Earth’s gravitational field. NASA created this lumpy version of Earth using models and data from satellites, which can detect minute differences in gravity at different locations. NASA also shared an interactive 3D model of the geoid that you can explore here, as well as a longer video. An analysis from the University of Nebraska using gravitational observations shows that soil moisture and shallow groundwater are both sitting in or near record-low territory in parts of the region.
