🔎In the first discovery of its kind, astronomers have detected the chemical silane on an ancient brown dwarf nicknamed The Accident, unlocking clues into the formation of clouds on gas giants planets. 🔗 https://t.co/znMjg7Qr1i Illustration: NOIRLab/NSF/AURA/R. Proctor

We work in style, even when there’s snow 😎❄️ This time, Cerro Pachón in Chile got about 6–8 inches of snow, and Cerro Tololo about 4 inches. 🎛️DJ: Fabrizzio Bruno (song: Vicarious- Tool) 📹NOIRLab/NSF/AURA/F. Bruno #snow #telescope #chile #science

No, the sky didn’t get brighter, it’s a photographic trick! This stacked image from Cerro Pachón 🇨🇱, shows hours of starlight captured in trails with the setting Sun, passing car headlights, and the laser beam from @Geminiobs South. 📸 @GeminiObs/NOIRLab/NSF/AURA/P. Horálek

Does anyone mind if we crack a window? 🪟 Keeping a telescope cool helps it take the best possible measurements. Luckily, @Geminiobs South is equipped with 10-meter thermal vents to cool off when things get heated. 📷@geminiobs/NOIRLab/NSF/AURA

Say it 3 times: Betelgeuse, Betelgeuse, Betelgeuse. Astronomers using @Geminiobs North found a hidden companion star orbiting inside Betelgeuse’s atmosphere, the first close-in companion ever seen around a supergiant star. 🔗 https://t.co/8PUn3aS4Fj 📷GeminiObs/NOIRLab/NSF/AURA

This long-duration, fish-eye view of @Geminiobs North looks like a snow globe, but with stars instead of snow. ☃️The motions of the ⭐️ were captured through the night, along with the Gemini laser on the right, and the 🌙 on the left. 📸@GeminiObs/NOIRLab/NSF/AURA/J. Pollard

The Universe really said, “let’s kick it!” ⚽️✨ Some nebulae form elegant spirals and clouds…K61 decided to become a soccer ball. 🤗 Nonetheless, Gemini North, one half of @GeminiObs, captured it beautifully. 😌 📷@GeminiObs/NOIRLab/NSF/AURA

🚨 Astronomers just found the closest-ever link between a supernova and a mysterious fast X-ray flash! 🌟💥 Turns out, some massive stars may explode with “failed” gamma-ray bursts—jets that never escape. 🔗 https://t.co/kdA6PFq9ra

🚨 It’s #AsteroidDay! ✅ Appreciating cosmic rocks ❌ No need to panic —we’re watching them 😌 Telescopes like @VRubinObs & @cerrotololo help spot, track, and study near-Earth objects. Because nothing says “I care” like monitoring 30,000 mph space boulders. 🪨 (You’re welcome)

❄️ Snow’s back at Cerro Pachón! ❄️ @Geminiobs South and our neighboring telescopes just got their second snowfall of 2025. Not a blizzard, but enough to turn heads (and domes) 😉. 📸 NOIRLab/NSF/AURA/S. Olivares & F. Bruno

Even remote, high-altitude telescopes like @Geminiobs North on Maunakea can’t escape light from satellite constellations. While invisible to us, they leave bright streaks in sensitive long-exposure images. 🛰️🌌 📷 GeminiObs/NOIRLab/NSF/AURA/J. Pollard
