Thanks for posting this link, and thanks to the writers/editors of
that story for (for once!) including a link to the actual research!
They're talking about

This is a nice piece of observational work, but it's not clear to me how
it's meaningful to call the their data "a singular example of discrete
self-similarity".

[The Earth is, to a reasonable approximation, spherical in shape.
Saturn is, to a reasonable approximation, spherical in shape.
Does this identity of shapes
[explicable in terms of the Newtonian mechanics
of hydrostatic equilibrium]
constitute an example of discrete self-similarity?]

ciao,
