A HUGE object spotted passing below the International Space Station has sparked a frenzy among conspiracy theorists online. - Callum Hoare
Thanks to some comments I tracked down the relevant lat/long of the object and matched up the terrain. So it's pretty much nailed down that whatever object this is is not in space. I did find it a bit off and out of place. If you want to explore yourself, here's some info...
Lat: 40.544835°
Long: 90.898370°
You can see in the image above a timeline from Nov 2016 through today.
That's pretty funny. I guess it kinda does look like some kind of shuttle or something though. But UFO does start with "unidentified". Just in this case, it wasn't even flying. :P
If you look closely at the 2016 photo you can see the thick white border that looks "space-shippy". But today it seems that artifact is gone and the full complex has been built. Funny though nonetheless how people will jump on a story without even a little research.
Not sure if I would classify that as funny. Rather sad really. It's quite common these days. Though perhaps it's just that we hear about it more these days.
