Does just "Andromeda" work for the galaxy? I'm not sure, because I was a little bit stressed, so I couldn't check if I spelled it correctly. If it doesn't, it probably should. Though technically the Milky Way would be correct (as it's in it, meaning it's the closest one), but I see what you mean, so it's fine. There's not a lot of time, but I kind of like that, forces you to think quickly, especially if you wasted probably close to a minute trying to think of the island before you realise the time is running out!
