Gemini PIs: The deadline for Phase 2 is quickly approaching! Please remember to finalize your program setup and send it to your CS for review by July 17th! @GeminiObs @NOIRLabScience #astronomy

Throwback post: Sun, clouds, a few tourists, rain, humidity, lasers, stars, galaxies, satellites, more lasers, Moon, and Sun at Gemini North! #Astronomy

Using the Gemini North telescope, one half of the International Gemini Observatory, astronomers traced high-energy neutrino IC 210922A to a star-forming galaxy 11 billion light-years away, finding the likely source of the ghost particles. #astronomy 📸Gemini Observatory/NOIRLab/NSF/AURA/ALMA

Here is a summary of observations from both Gemini telescopes in June 2026, divided by instrument and color-coded by location. Gemini's Zorro 🦊 took the most observations again last month, totaling over 600! #Astronomy

Throwback post: The All-sky camera at Gemini South got a pretty good view of the Lunar eclipse last night! Note the very sharp decrease in brightness between 12-17 seconds! #discovertogether #Eclipse #EclipseLunar #Eclipse2022 #Astronomy

The Anglerfish Cluster. This galaxy cluster is so massive that its gravity warps space-time, turning it into a natural cosmic lens. Hubble saw only part of it; Gemini North revealed the rest. #astronomy 📸: International Gemini Observatory/NOIRLab/NSF/AURA

It's #NationalCameraDay, and we've got a great one, built by SLAC National Accelerator Lab 😎 Meet NSF–DOE Rubin Observatory's LSST Camera 📸 It captures an area of sky 45 times the size of the full Moon — that huge view is what'll enable Rubin to capture the entire visible sky every few nights!🔭🧪
