Our galactic neighbor Andromeda has a bunch of satellite galaxies — and they're weirdly pointing at us

Our neighboring Andromeda Galaxy (Messier 31, or M31) appears to sport a lopsided arrangement of satellite galaxies that defy scientific models, stumping astronomers who are also trying to figure out why so many of this galaxy's family members point in our direction. All but one of M31's brightest 37 satellites are on the side of the Andromeda spiral that faces our Milky Way galaxy – the odd one out being Messier 110, which is easily visible in amateur images of the Andromeda Galaxy.

  1. Isn’t Andromeda larger than the Milky Way?
    Are we just another satellite galaxy?

    Is it possible that this is another “Hot Jupiter” scenario and we can just see the galaxies closer to us more clearly?

    [Space.com](http://Sapce.com) bringing the hard science I see:

    >If something in the cosmos appears a certain way, it’s usually because something has caused it to be like that. Still, there’s no firm evidence pointing towards any particular explanation so far, other than that for this alignment to be present now, its cause must be recent.

    The first sentence – eeesh. And then rounding out with, there are no explanations so this must be the explanation.

  4. And there is no bias toward discovering dwarf galaxies when they are in plain view and close to us, rather than hidden behind something and farther from us?

    Commander, we’ve just finished a security scan. Andromeda’s coming with its gun ports open.
    She’s armed for a fight.

  6. Know anything about cephalopods? We’re about to get out asses kicked by calamari.

    That’s because they are just png billboards they always face the camera that way we don’t need to render a full model
