Gegenschein at the Teide Observatory

Caption

A vertical panorama obtained from the Teide Observatory, which shows a bright Zodiacal light centred on the Teide volcano under snow (Teide National Park, Tenerife), with the Milky Way in winter, from the star Sirius to the left (this is the brightest star in the night sky) to the double cluster in Perseus on the right. In the upper part of the image there is the faint Gegenschein which can be seen only with very dark sky. This image was taken within an initiative against light pollution by the European project STARS4ALL (www.stars4all.eu). STARS4ALL is designed to increase social sensitivity about the negative effects of artificial light on human welfare, biodiversity, the visibility of the stars, security, and energy waste.
