🦊 Two hunters on a break.
A Culpeo Fox is basking in the warm sunlight, in front of our 3.6-metre telescope.
Just like the Culpeo uses its senses to hunt for rabbits, our telescope uses HARPS to scour the cosmos for new exoplanets.

The skies above Paranal are at risk from a proposed industrial megaproject.
This would be located in the vicinity of ESO's Observatory. If constructed, it would irreparably impact astronomical observations.

World's darkest and clearest skies at risk from industrial megaproject
On December 24th, AES Andes, a subsidiary of the US power company AES Corporation, submitted a project for a massive industrial complex for environmental impact assessment. This complex threatens the pristine skies above ESO’s Paranal Observatory in Chile’s Atacama Desert, the darkest and clearest of any astronomical observatory in the world [1]. The industrial megaproject is planned to be located just 5 to 11 kilometres from telescopes at Paranal, which would cause irreparable damage to astronomical observations, in particular due to light pollution emitted throughout the project’s operational life. Relocating the complex would save one of Earth's last truly pristine dark skies.
