  Something like this is probably close (although probably not identical):

camera { location -z*5 look_at 0 angle 35 }

sphere
{ 0, 2 hollow
  pigment { rgbt 1 }
  interior
  { media
    { emission 1
      density
      { spherical density_map
        {
          [ 0.0 rgb <0, 0, 0> ]
          [ 0.25 rgb <.5, 0, 0> ]
          [ 0.5 rgb <1, 1, 0> ]
          [ 0.75 rgb <.5, 0, 0> ]
          [ 1.0 rgb <0, 0, 0> ]
        }
        turbulence 1.5
        frequency 2
      }
    }
  }
}
