This is very interesting stuff my friend. I'm actually a huge astronomy fanatic lol I've been studying space and things like this for a long time, and I had once considered going into the field but turned out I didn't want to do that for a living, but besides that I watched about half of the video.
I'm very skeptical when I see things, because as someone who likes this stuff, I want to be knowing that I'm seeing 100% fact. So one thing about this video I found interesting, is if you google the title it shows up all over the internet, with the same title. That's kind of odd, but that's not a reason to lose credibility. I'd just like to know the source of the info. The video info seems real, but it's always good to predict every scenario.
According to all of the dates this video was made literally hours ago. Some of these sightings look really incredible, but some (like that spiral) seem extra incredible.
This link has an explanation for the spiral
This is from the "Norway Spiral". I think it was told to be a rocket that was launched into the sky. Who knows..
I remember once a rocket in Virginia was launched and I saw it in the sky with my friend and we had no idea what it could till I looked up events occuring that night. It was literally the strangest thing I had ever seen myself in the sky, and turned out to be a stupid rocket. I definitely believe in the extra terrestrial, however there's so much non-ET things to sift through it becomes difficult to know what you're looking at..
