Have you ever seen clouds like this on mother Earth !

I thought we were being invaded when I saw this !   

Reminds me of a Sci Fi Film scene that I have seen somewhere.

Very different! I have never seen this formation....
Closest I would say was like cotton ball clouds...

The clouds in your OP pics are called mammatus.
Very interesting, thanks Astro!
