At the page at the Popular Science site where I first saw this video, the author says:
The video below was captured by Stephane Guisard and Jose Francisco Salgado at the European Southern Observatory’s Very Large Telescope (VLT) in Chile’s Atacama Desert. And it might make you cry.
What makes this time lapse particularly amazing — because we’ve all seen plenty of time lapse videos of the night sky — is the four telescopes in the foreground. Watching these instruments work against a black background would be endlessly fascinating on its own. Unfortunately you won’t be able to pay them too much attention. Because damn, what a sky.
Yes. Damn. What a sky.
