Eerie black ring-shaped formation filmed in the sky over Argentina

[UM-Bot]

As it turns out, this peculiar aerial phenomenon actually has a conventional explanation.

Oddly beautiful!

Yep but VKO (Very Known Object ^^) this is the exhaust of a chimney

Swarm of mosquitoes??? WTH? Black flies and horse flies sometimes swarm in the Arctic but that size is 100% impossible even for them. That's just a ring of smoke, your can see some of it near the ground. It came either from a long-unused chimney, like Amorlind said, or after firing a ceremonial cannon.

Fascinating!!

Not a swarm of mosquitos.  Smoke, sure, apparently from some nearby fireworks.  Nice visual, anyway.

Why does this merit 'eerie', 'mysterious' or any other 'spooky' adjective?

Here's an example: Smoke Ring

Well, whatever it is, what I see (or think I see) is an opaque, parachute-shaped membrane above the ring, 
and what looks like tentacles the same color as the membrane, hanging down  under the ring. 

In other words, like a giant jellyfish.

Wow. Maybe you can circle it for me..?

If you ever started an old diesel truck or bulldozer, you would see those black smoke rings blown out of the exhaust before the engine catches and turns over on its own. Of course if you were tasking the picture, you would know exactly what it was.

Yes, sure. but I have a bunch of stuff to catch up on. It doesn't take much for my battery to run low now. If not tonight, later.
