Star trails over La Silla

A combined series of nighttime exposures captures these impressive star trails over ESO's La Silla observatory. The stars appear as trails because of the apparent daily motion of the sky, which is, in fact, due to the rotation of the Earth on its own axis.

This photograph was taken by ESO Photo Ambassador Alexandre Santerne.
