While we always like to conclude 'aliens,' this flying saucer cloud is supposedly not 'aliens.'

This unusual cloud 'hovered' over the Boulder area for over an hour, Fox News reported, while other clouds moved around it. It seems out of the ordinary, but unfortunately, there is a logical explanation that doesn't involve UFOs.

*Cue down the Twilight Zone music.*


The National Weather Service in Boulder shared a time lapse video that shows how the cloud hovers for a long period of time. However, they explained that this is a 'lenticular cloud.' It's caused by fast-moving air that is 'forced up and over a topographic barrier that is oriented perpendicular to the direction from which the upper-level wind is blowing, such as mountains,' Fox News said.

In other words, it's because mountains and air and moisture and wind and stuff.

'These lens-shaped clouds typically form where stable, moist air flows over a mountain or a range of mountains,' weather site Earth Sky explains. '...Lenticular clouds are often mistaken for UFOs (or 'visual cover' for UFOs).'

Aliens or science — still not something you typically see every day here.
