In the news today, they announce a first possible planet outside the Milky Way galaxy has been spotted, in the Whirpool Galaxy. https://www.bbc.co.uk/news/science-environment-59044650

Surely the first planet to be possibly be discovered was in 2009 . https://www.newscientist.com/article/dn17287-first-extragalactic-exoplanet-may-have-been-found/

The Question is, was the Andromeda planet later discounted for the Whirlpool planet to become the first or bad reporting.

  • $\begingroup$ New Scientists wouldn't let me view the correct article so i linked the article which i could view with just the one line mentioning Andromeda's planet. To avoid confusion, I've linked to the more appropriate article. $\endgroup$ Oct 25, 2021 at 22:21

The New Scientist article mentions that the star is “an interloper from another galaxy” and that it is “2300 light years from Earth.” This places it well inside the Milky Way.

So, the star and its planet[s?] were probably made in another galaxy, but they are not in another galaxy now.

Today’s announcement does remain true.
