The night sky gleams with stars, nebulas and galaxies over ESO's Paranal Observatory in Chile. Three of the four moveable VLT Auxiliary Telescopes stand below the majestic sky. The units feed light into the Very Large Telescope Interferometer, creating a telescope greater than the sum of its parts. Image released Jan. 6, 2014.
