“Today, we exceed our planet’s capacity to sustain life, depriving billions of basic needs amid rising conflict. Yet, with collective will, we can bridge the gap between knowledge and action to safeguard life-support on Earth.” Www.iceblog.org

A set of workhorse telescopes can be seen in this time-lapse captured on Cerro Pachón in Chile. In the foreground is the SOAR Telescope. To its immediate right is Gemini South. Farther still to the right sits NSF–DOE @vrubinobs.bsky.social. #astronomy

When your Gen Z co-worker says RICO, the name of a print server, but you can't respond with "Suave!" because they won't understand, you'll have to explain it, and both of you will just end up disappointed.

Happy Tuesday! We're still keeping you updated with what the network has to offer on the Greenlandic crisis - starting with Rob Huebert's recent comments with Canadian Geographic. canadiangeographic.ca/articles/buy...

The interstellar visitor 3I/ATLAS has been stealing the spotlight lately. But it’s not the only comet capable of putting on a show!  Here you see C/2024 G3 (ATLAS), above Paranal early last year. https://www.eso.org/public/images/potw2505d/  📷 Y. Beletsky (LCO)/ESO #flashback 🔭

One of the big summer infrastructure projects is digging of a new intermediate sewer outfall tunnel. Here is a pic from Rich Overbeck earlier this summer early on in the project. #Antarctica #soutpole @NSF

This past weekend was the annual #southpole marathon! Since 2011, the marathon has been run annually in January (yes, outside!), usually consisting of 6-8 loops around station. All-time record is 4hrs02min by Ricky Gates in 2011! Pic by Michel Adamic. #Antarctica @NSF

Craters so beautiful, haters will say it's AI

This guy makes life better everyday. I ❤️🐶☕

Twilight over Cerro Pachón is unlike anywhere else on Earth. This mountaintop is home to the Gemini South telescope (right) and the 4.1-meter Southern Astrophysical Research telescope (left), both programs of @noirlabastro.bsky.social @aura-astronomy.bsky.social #astronomy

Lately I've let myself get stuck in a 2011-to-2014 nostalgia vortex (when things made sense) and one of today's things was Primeval: New World. The concept of people vs dinosaurs in Vancouver can do a lot of heavy lifting. And the intro remains excellent. www.youtube.com/watch?v=XcW8...

We have an SR Hadden. Now we need an Ellie Arroway and a Palmer Joss to get this Contact remake rolling. arstechnica.com/space/2026/0...

High on Cerro Pachón, Gemini South works the night shift, gathering faint starlight from across the Universe. By day, 668 solar panels take over—powering ~28% of operations. 🌙☀️ #astronomy 📷 International Gemini Observatory/NOIRLab/NSF/AURA/P. Horálek

We’re looking for a volunteer site host to help us work with hatchery winter steelhead at an acclimation site in Canyonville (Douglas County) through April 30. myodfw.com/news/volunteer…

Against a backdrop of snow and volcanic rock, the observatories at the summit of Maunakea in Hawai’i harbor some of the world’s most advanced astronomical equipment, including Gemini North, the open silver dome on the higher ridge. #astronomy Gemini Observatory/NOIRLab/NSF/AURA/J. Pollard

We have successfully drilled 200 metres of sediment core from beneath the ice sheet at Crary Ice Rise! The pipe is still spinning - with a bit of time up our sleeve, we’re not stopping drilling yet, as we continue to drill back through the geological archive hidden beneath the ice. 📷 Ana Tovey

It's a beautiful day in this neighborhood, a beautiful day for a neighbor 🎶 NSF–DOE Rubin Observatory is in good company on Cerro Pachón! 🔭 From right to left: The 8.4m Gemini South telescope The 4.1m SOAR Telescope Rubin's 1.2m Auxiliary Telescope And of course, Rubin itself✨

The Lick Observatory, a research center on the summit of 4,200-foot Mount Hamilton near San Jose, will remain closed as workers assess the damage caused by a storm and stabilize the building.

Welcome to the party, pal.

Watching the #Pluribus finale? Remember those huge dishes in the opening of Ep 1? 📡 That’s the NSF Very Large Array in New Mexico - the most versatile, widely-used radio telescope in the world - and yes, it’s open to visitors! VisitVLA.com 📸 Credit: Chris Smirnoff #VisitVLA #AppleTV #Astronomy

Milestone achieved: Shovel snow for the first time

Can we hear a little commotion for the AuxTel? 👏 Rubin's 1.2m Auxiliary Telescope measures how Earth’s atmosphere affects incoming light by monitoring well-studied stars. Scientists use this information to make Rubin data better — with a facility this precise, every bit counts! 🔭🧪

Happy Friday! 🪐 🐾 This week's #Planetary Pet is Chance, and he needs help finding a home! If you, or anyone you know, might have a space in your heart and home for this guy, please send an email with the subject line “Chance” to [email protected].

'Bout time

It’s a very Crary Christmas for our on-ice team in Antarctica! After several weeks of weather delays preventing them getting out to our deep-field camp at Crary Ice Rise, on Christmas Eve the team received the best possible present – a Basler flight to Crary! Crary Christmas from SWAIS2C!

Have a good one, News Eaglets.

Wishing you a bright and starry holiday season! ✨ We hope you celebrate, relax, and spend time with loved ones. And with Skysynth, you can enhance your festive cheer by experiencing Rubin data through sound! 🔭🧪 Press play and enjoy a cosmic soundtrack ✨ skyviewer.app/skysynth

The sky above Rubin is giving some serious festive-season glitter vibes ✨ NSF–DOE Rubin Observatory's dome is coated with aluminum, which reflects sunlight during the day and cools off slowly at night. This prevents thermal turbulence near the telescope, keeping images crisp. 🔭🧪

I don't know art but I know what I like (West Coast Indigenous paintings and carvings).

ESA could bring in a ton of money if it installed stadium seating on those flame diverters.

Pueo is launching! #Antarctica #southpole @NASA Watch live here: video.ibm.com/channel/nasa...

From a foggy Lake Temescal walk this morning.

Three days after launch, the GAPS (dark matter) balloon is doing well. Waiting for PUEO to launch, the balloon facility webcam is still capturing interesting activity: a LC-130 on deck and an Emperor penguin in the foreground @NASA #Antarctica www.csbf.nasa.gov/antarctica/p...

It’s been a busy semester at OCEH! ❄️ As the year draws to a close, we’re happy to share our third newsletter, capturing a cross-section of our work - from music and anthropology to food systems and environmental art. Read the full update here: shorturl.at/q0VXh

First pics are in from our deep-field camp at Crary Ice Rise! To melt a hole through the 500m ice sheet we need hot water, and there’s no shortage of a crucial ingredient - snow. The team made ’seed water’ by melting snow in a small tub. They use this to melt more snow in our big flubbers.

When we find out that aliens exist, do we still need to go to work the next day or............

Our new SOXS instrument has made its first observations! Installed at La Silla, it will observe fleeting cosmic events such as supernovae explosions or fast-moving asteroids.  https://www.eso.org/public/announcements/ann25011/ 🔭 🧪 #instrumentation 📷 P. Schipani/INAF
