I don't get it....what's wrong with the article's astronomy. It says that she's the most well known star (which one could argue Polaris is.....(aside from the sun of course)).....and it says she's been shining "brightly".......which Polaris certainly does do. If it had said "brighest"...perhaps there could have been a problem....but I didn't really find anything all that off about the article's astronomical references.
(except the speed thing...it says the other lady is making a speedy ascent into the sky.....although I guess the ascent of a star is pretty much a constant with the earth's rotation and the star's relative position to it.)
