Does our own Milky Way have a similar disk of light?
What up with word "boffin" or "astroboffin" as we have here? I first recall hearing (or rather reading) it just some months ago. Boffin sounds like some kind of bird. Is it the same as a "maven," which I think is Yiddish and proabably much older. Does it mean a expert or just an enthusiast or what? (I’ve looked it up, but still am not sure.)
