A new, highly detailed map of Jupiter's magnetic field based on data from NASA's Juno spacecraft renders in high resolution a mysterious region of the field nicknamed the Great Blue Spot (GBS), an isolated and intense patch of magnetic flux at the planet's equator. This orthographic plot shows the radial magnetic field from a vantage point above the GBS, compared to zonal winds measured by tracking the movement of surface features. The GBS appears to be distorted by the winds, with westward zonal winds south of the GBS pulling the field to the west and eastward zonal winds north of the GBS stretching the field toward the east.
