Paper day! Excited to share our new paper (my first First-Author haha~) where we examine Gaia-confirmed YSOs in the Taurus star forming region with VLASS & find a really cool radio luminosity-spectral type dependence :D!! Here’s the arxiv preprint link: arxiv.org/abs/2501.06188
The Radiowave Hunt for Young Stellar Object Emission and Demographics (RADIOHEAD): A Radio Luminosity${-}$Spectral Type Dependence in Taurus${-}$Auriga YSOs
We measure the radio continuum fluxes at the locations of all Gaia${-}$confirmed members of Taurus${-}$Auriga using Karl G. Jansky Very Large Array Sky Survey data (VLASS; 2${-}$4 GHz, $σ_{\rm{VLASS}}...

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.
