In the glittering sky above Rubin Observatory shines the Pleiades, or M45: an open star cluster with at least a thousand stars!✨ You don't need to be under some of the clearest skies on Earth (like Rubin is) to see M45! It's visible from October through April from most latitudes. 🌎 🔭

This week’s image is of the young star HR4796A! This image shows the star and the scattered light from a surrounding disk under normal light (left) and polarized light (right). Check out the 🧵 for more papers involving star systems! #Astronomy 📸 in thread

🚨 Attention! 2026 Gemini Large & Long Program (LLP) letters of intent are due next week (Feb 16, 2026) ⚠️ IGRINS2 and MAROON-X will both be offered at GN, but they share the same port, so won’t be available at the same time. Good news: B1 time is back again! www.gemini.edu/observing/ph... #astronomy

This week’s image is of Abell 1489! Gemini’s GMOS-N captured this striking image, where nearly every visible object is a galaxy. These crowded neighborhoods are excellent for studying the life cycle of galaxies. Check out the 🧵 for papers on galaxy clusters! #Astronomy 📸 credits in thread

This week’s image is of the spiral galaxy NGC 7331! This galaxy may look like our Milky Way, but it doesn’t behave the same. For instance, did you know that NGC 7331’s central bulge rotates in the opposite direction to its disk? Check out the 🧵 for papers on galaxies! #Astronomy 📸 credits in thread
