November - Sun halo at Paranal

Like the Moon halo pictured for May, a Sun halo shines from the sky above ESO’s Paranal Observatory in Chile. One of the four Unit Telescopes of the Very Large Telescope (VLT) reflects this breathtaking daylight phenomenon.

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 every year. With the VLT, the first image of a planet outside our Solar System was obtained in 2004.
