Gravity satellite yields 'Potato Earth' view
It looks like a giant potato in space.
And yet, the information in this model is the sharpest view we have of how gravity varies across the Earth.
The globe has been released by the team working on Europe's Goce satellite.
It is a highly exaggerated rendering, but it neatly illustrates how the tug we feel from the mass of rock under our feet is not the same in every location.
