A dual-axis combination chart titled “Refereed papers with Gemini data and US participation” shows publication and citation statistics from 2017 to 2021. The primary vertical axis on the left represents the “Number of citations per year,” ranging from 0 to 9,100. Each year features a stacked bar chart representing total citations, with the colors indicating the breakdown: blue for refereed citations, red for non-refereed citations, and grey for total citations. The annual citation totals are displayed as numbers above or within each bar segment. The secondary vertical axis on the right represents the “Number of refereed papers per year,” ranging from 0 to 240. A teal line plot spans the years, showing the trend in annual paper production, with specific values labeled above key data points: 151 in 2017, 152 in 2018, 208 in 2019, 198 in 2020, and 89 in 2021.
Throwback post: Summary of refereed papers using Gemini data with US participation, from 2017 to today. More than 19,000 citations with an h-factor of 58. Very impressive numbers!

🚨Attention Gemini 2026A PIs! The Phase II deadline is January 16. Make sure your observations are fully set up before the deadline! @noirlabastro.bsky.social #astronomy
Big main character energy here from Gemini South. Sure, the telescope conducts world-class research and captures jaw-dropping images with its 8.1‑meter mirror… but honestly, it knows it’s photogenic too. #astronomy

Do you have Gemini GMOS MOS and IFU data and don’t know how to reduce it? Don’t panic, we have here the solution for you: the GMOS Data Reduction Cookbook nsf-noirlab.gitlab.io/csdc/usngo/g... #astronomy
Want to know more about us? The US NGO is part of the NSF NOIRLab. Our main goal is to support US Gemini users in the phases of the astronomical observing cycle, from proposal preparation to data analysis. More info about us and what we do 👉 noirlab.edu/science/prog...
The US partner received 266 Gemini proposals for the 2026A semester. About 75% of those were submitted within 48 hours of the (extended) deadline (we are not looking at you 🙂)! Our Time Allocation Committee will soon review and rank the proposals, so stay tuned! #astronomy

From @noirlabastro.bsky.social: These images show disks of gas, dust, and other materials orbiting young stars. The disks may eventually coalesce into newborn planets. #astronomy @aura-astronomy.bsky.social

Take a look at the new R400 grating available at Gemini North! It offers an improved throughput compared to the old R400 grating and it will be permanently installed on GMOS-N from August 1st, 2025 (HST). #astronomy
Grating B480 of GMOS-N is back in business! The grating has been secured in his holder position and is ready for science again at Gemini North. #astronomy
How busy are our Gemini telescopes every night? Due to its queue operations, we observe different programs, instruments, and weather conditions. Everything to maximize the resources we offer to our amazing community. Check all our time-lapse videos here: noirlab.edu/science/obse... #astronomy
From @noirlabastro.bsky.social: Remember that asteroid that’s been all over the news? Using Gemini South, astronomers constructed a 3D render of its hockey-puck shape 🥏 and determined it likely came from the main asteroid belt!🔗 noirlab.edu/public/news/...

The GMOS team at Gemini North has an update on the air bubbles found in the instrument's lens interfaces. More information and mitigation strategies are given here: www.gemini.edu/news/instrum... @noirlabastro.bsky.social #astronomy
Attention Gemini GHOST users: An issue was identified with the ThAr arc lamp in GCAL. The lamp was replaced, and PIs with data taken between 2025-02-14 UT and 2025-03-25 UT are advised to avoid calibration lamps for those dates. Details are given here: www.gemini.edu/news/instrum.... #astronomy
There is still time to get your 2025B Gemini proposal submitted. The deadline for the US is March 31st. Please reach out to us if you want to talk about your proposal or have instrument questions! More info here: gemini.edu/observing/ph... #astronomy

The US National Gemini Office is now on @bsky.app! We are part of NSF NOIRLab and support Gemini users in all the stages of the astronomical observing cycle, from proposal to data reduction. Our website is full of info and we will post content for the entire community! noirlab.edu/science/prog...
Did you know you can access reduced GHOST 👻 data directly from the Gemini Archive? Just search for observations made with GHOST. The reduced files will be highlighted in yellow for both the red and blue channels and have the suffix _dragons.fits or _calibrated.fits.
And thank you @emily.space for organizing and allowing the migration! 😉
