"Halo, World!"

A sun halo shines from the sky above ESO's Paranal Observatory. In the lower right corner the light is reflected from one of the four Unit Telescopes of the Very Large Telescope (VLT), ESO's flagship telescope. The VLT is the world's most advanced optical instrument, and the world's most productive ground-based facility, enabling it to take advantage of the 300 clear nights Paranal has per year. As demonstrated in this photograph, however, breathtaking phenomena are not only visible during the night.
