On: A Black Hole Threw a Star Out of the Milky Way Galaxy

"The Black Hole at the Center of the Milky Way Threw a Star Out of the Galaxy" would probably be an alternate way to write the headline using the definite article.

Agree that _just_ an article swap leaves the headline worse off.

I agree this is a better headline. In the original, I was left wondering if it was possible for a black hole outside of our Galaxy to eject a star from ours.

That should be impossible (unlikely), but it could have been a smaller black hole around the galaxy.
