File:Dizzying Star Trails Over SEST.jpg
In this image, we see a crowded night sky filled with star trails, a result of the camera's long exposure time. The starlight is reflected back at numerous different angles towards the camera from the giant parabolic dish. In the background, the ESO 3.6-metre telescope stands in its dome, silently surveying the cosmos.
This dizzying picture of the SEST telescope at La Silla was taken by ESO Photo Ambassador José Joaquín Pérez.
