Reading the article I figured this event was in our galaxy but it’s 22 million light years away! Makes sense that other telescopes couldn’t resolve it.
The Milky Way is only 100k light years across. So one of those two things can't be true. The article says: "N6946-BH1 is in a galaxy 22 million light-years away". So it's a different galaxy.
Yep! That's what they're saying - that they had mistakenly thought it was in the Milky Way until they saw that it's 22 million light years away.
I think the GP was just ambiguous with their wording. I think they meant "I originally thought this was within our galaxy, but later discovered it was 22 million light-years away."
