You Mysterious Saturn Hexagon you, where did you come from? Who made you? There are no Russians in Saturn? Or are there? Whatever, you freak me out even more than the Norwegian spiral, because you can eat two Earths simultaneously.

That’s how big this thing is: Its diameter is wider than two Earths. Nobody really knows what causes the hexagon, and why it has this exact geometric shape, something which is extremely rare – if not impossible – to find in atmospheric formations.

The Saturn hexagon left everyone speechless when Voyager sent the first images of the phenomenon, and still baffles scientists all over the world, like Kunio Sayanagi, a Cassini imaging team associate at CalTech:

The longevity of the hexagon makes this something special, given that weather on Earth lasts on the order of weeks. It’s a mystery on par with the strange weather conditions that give rise to the long-lived Great Red Spot of Jupiter.

If you saw this over your head, what would you think? Aliens have come to kick our asses? God has come to kick our asses? Apparently, the bizarre cloud formation seen in Moscow recently is just a natural phenomenon.

Talking to the Daily Mail, a spokesman from Moscow’s weather forecasting service said: “Several fronts have been passing through Moscow recently, there was an intrusion of the Arctic air too, the sun was shining from the west – this is how the effect was produced.

“This is purely an optical effect, although it does look impressive,” he added.

Ok, so it’s just clouds — but when you watch the video you still expect an alien ship to drop through that hole with lasers blazing. [Telegraph]
