I’m delighted to share the most recent publication from our PHANGS (Physics at High Angular resolution in Nearby GalaxieS) collaboration, detailing physical properties of ~100,000 star clusters and compact associations in 38 nearby spiral galaxies. 1/4 in 🧵 ui.adsabs.harvard.edu/abs/2025ApJS...

Galactic bubbles like never before! @eric-koch.bsky.social introduced BubbleZoo, a citizen science project cataloging JWST’s mesmerizing voids in galaxies, at the JWST session on galaxies at the 6th Shaw-IAU Workshop! 🔭 #astroedu

New data release: The z0MGS_Dust project consists of Herschel images from PACS and SPIRE available for 1578 galaxies, dust emission parameters for 819 galaxies, and integrated photometry and dust parameters for 877 galaxies. irsa.ipac.caltech.edu/data/Hersche...

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.

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

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.

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.
