Interplanetary, interstellar, intergalactic

The Financial Times proves that familiarity with the upper classes and a dedication to enabling companies to make giant piles of cash is not synonymous with literacy.

This article, entitled, We Should Not Be Too Excited About Intergalactic Neighbours, is by Anjana Ahuja, who is a science commentator.  She's writing about a planet that's 12 light years away from Earth.

It's quite probable that the headline was written by a sub-editor, not the science commentator, but even so, believing that twelve light years away is "intergalactic" means the person is either dull and uninterested in things or is in such a hurry that it was impossible to look it up. Neither of those possibilities makes me inclined to trust the Pink 'Un. Except on stocks.
