This week’s image is of NGC 6334, the Cat’s Paw Nebula! This emission nebula’s red glow is due to light from the enshrouded stars exciting the surrounding gas. Check out the 🧵 for papers featuring nebulae

Did you know that Astro Data Lab hosts ready-to-use Jupyter notebooks for Gemini Observatory data reduction with DRAGONS? Simply launch a notebook in Astro Data Lab, access the latest tutorials, and start reducing your data directly in the cloud! Find them on 04_HowTos/DataReduction. #astronomy

From @noirlabastro.bsky.social: The wildlife near our observatories didn’t sign up for the night shift. These neighbors are part of the unique ecosystems that surround our sites in Chile. We’re guests in their home, so we keep the lights low, and the camera zooms high. #astronomy
