For the last 134 years people have photographed the andromeda galaxy, but everyone up until now has missed this giant undiscovered nebula!

@sandorkruk to be fair that's a BIG patch of sky in that image. Like several full moons across.. and you need really deep and precise imaging to pull something so LSB out... so I don't find this too surprising.
@sandorkruk (cool though to this that it was hiding there all this time!).
@karenlmasters @sandorkruk i poked very briefly at the rnaas and could not satisfy myself that this was not Galactic. Do we know this is not Galactic? It looks a lot like the magnetized structures we have been studying in the MW for about a decade.
@jegpeek @karenlmasters @sandorkruk Agree. But such a cool mystery!
@rdrimmel @karenlmasters @sandorkruk has someone looked in the HI?
@sandorkruk @rdrimmel @jegpeek @karenlmasters could it be super foreground? Like Local Cloud (10pc) or Local Bubble (few hundred pc) range?
@jradavenport @sandorkruk @rdrimmel @karenlmasters it sure could. I would bet mostly likely at the 100-300 pc distance range.

I haven’t read the paper so I’m curious, but what is the probability of a galactic structure with the same orientation as Andromeda in that direction?
@crawfordsm @jradavenport @sandorkruk @rdrimmel @karenlmasters by eye they look askew by maybe 15 degrees? So 1 in 12 chance of being this well oriented or better at random?
