I don't think the logo is the LMC. Yes, there is a "C" shape in there, but if it's the C we're looking at it's got those three "connections" coming off it, which the LMC doesn't have. Also, why would it be described in negative space like that?
I'm more on the side that it's Barnard's loop plus two other nebulae as seen from the right location. Or it's something else entirely.
BUT
The fact that's getting ignored in favour of greed and general enthusiasm is - it's an artificial mark. These things are BRANDED. They BELONG to somebody.
Now, some Tinfoilery, brought to you by the Shard Broadcasting Corporation
Tinfoil 1: The UAs are a perimeter fence around the barnacle farm. Palin's research noted that they can broadcast over VAST distances. They encode a little drawing of whoever they see and send the data, reporting perimeter breach and by whom. Why morse, and why stellar data in HUMAN terms? - I dunno. Why ask me? Who are you anyway with your impertinent questions? Get out of my office, you punk, before I make a nice hatstand out of you!
Tinfoil 2: The UA's are part of the barnacle breeding cycle.
Tinfoil 3: The Anaconda has brought them here from wherever it has been collecting all those rare materials. Now they are here, they are breeding out of control.
Tinfoil 4: The barnacles and the UAs are part of a mycoid revenge plan by Thargoids, or maybe just some random alien bunch. UA's are noisy and attention grabbing - we get nosy, pick 'em up, get infected and start a nice new barnacle farm.
Tinfoil 5: The UAs are a part of the barnacle farm harvesting method - the barnacles do their thing, and the goodness is packaged into a UA, shot up into space where they can be conveniently collected with having to land at each and every barnacle ranch. They even make a loud noise and transmit where they are to make it easier.
Tinfoil 6: A combo of the above.
Tinfoil 7: The logo is very close to one of my preliminaries when I designed the Canonn logo, which was to be a C in a biscuit. Perhaps LAB69 have been digging through may old papers, and concocted this whole thing to justify their budgets.
Either way - these are not OURS. I'm not saying we should leave them alone completely, but we shouldn't go nicking them, and shooting them etc. Xenobiological study should be done in a more Attenborough style than a Darwin shoot 'em and eat 'em style.
