Right in time for #Halloween 🎃
Our VST has spotted a spooky bat flying over Paranal. But fear not, it's located 10,000 light-years away.
This "cosmic bat" is in fact a large cloud of gas. Let's fly through it in this video...if you dare! 🦇

The ELT doors have moved for the first time. This was no small feat, as each door will weigh 650 tonnes once completed.
The ELT dome & its doors will guard the telescope from the harsh conditions of the Atacama Desert.

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.
