1/ This pic I took a few years ago at ESO's Paranal Observatory in #Chile almost didn't look like this! I was about to go to sleep when I saw that the folks at the UT4 telescope were using the lasers, so I decided to snap a quick shot.

But when reviewing the image on my camera's screen I noticed something was off. I looked up and saw that some clouds had rolled in within seconds! Here you can see the lasers going through two cloud layers.
