I took this pic a while back at ESO's Paranal Observatory in Chile. It shows the four Auxiliary Telescopes of the VLT Interferometer, gazing up to the sky. These telescopes work together, achieving a spatial resolution similar to that of a massive telescope as large as the separation between them.

Curious about how this works? Check out our interferometry explainer: https://www.eso.org/public/teles-instr/technology/interferometry/

@astro_jcm In that picture, AT3 is clearly looking elsewhere, though... Perhaps it didn't like what the others saw? ;-) More seriously, we can conclude that they observed with AMBER, haven't they?

@leo AT3 was clearly not having it that night :D AMBER had not been decommissioned yet back when I took this image, so that's indeed a possibility. I'll dig the EXIF data later and cross-check it with the archive to confirm it.
