Look, I'm not taking sides in any silly Planet X debate. I was only
making the observation that you should not use an extremely derogatory
expression like "yellow rag" in reference to a responsible digest of
scientific news like New Scientist, based merely on a catch-line quoted
in a Usenet post and apparently without knowing the publication or even
bothering to look at its website.
For your information, the article in question (actually just a news
brief) mentions that when Ulysses approached the southern region of the
Sun, "The field lines were expected to become more bunched and intense
[ ... ] 'Instead, the strength of the magnetic field remained
absolutely constant,' says Richard Marsden, a project scientist on
"The only reasonable explanation, says Marsden, is that the Sun's south
magnetic pole is large and diffuse."
Which is what you're saying and what any sensible person should expect.
