🔭 Now it's official, the nebula was never in Andromeda!
Our paper has been published and we show that the large 🧪 oxygen nebula is in the Milky Way.
This arc was discovered by amateurs photographing Andromeda with an [O III] filter, and now we have new things to say... ⚛️

We've been following 3I/ATLAS from @cefca-oaj.bsky.social in Spain (Teruel)!
This is just the 3rd interstellar object that we see enter the Solar System.
I created this video with the observations🔭 we have made: you can see the comet moving through the field of stars.
We hope to get more data!
