See code below. The trick is to have a mostly transparent pigment and a very
dense scattering media.

light_source{-z*100 rgb 1 rotate x*30 rotate y*140}
camera{
  location -z*7
  direction z
}
superellipsoid{<0.3,0.3> rotate 45
    hollow
    texture{pigment{rgbt <1,1,1,0.8>} finish{ambient 0.1 diffuse 1}}
    interior{
        media{scattering{1,8}}
    }
}
