BREAKING: The largest 3D map of the Universe is now complete 🌌

Last night @desisurvey, mounted on the Nicholas U/ Mayall 4 meter telescope at @KittPeakNatObs, finished its 5-year survey of the cosmos, mapping 47M+ galaxies and quasars.

Golden hour at Cerro Tololo 🌅

For a few minutes each evening, the mountains around NSF @cerrotololo in northern Chile are transformed by the warm light of the setting Sun.

Looks like a pile of glitter? Think much, much older. ✨

This is NGC 6723, a globular cluster also known as the Chandelier Cluster.

Well, that went by fast 👀

NSF @NOIRLabAstro is turning 7!

In 2019, observatories and programs across Chile, Arizona, and Hawaiʻi came together under NSF NOIRLab as one national center for nighttime astronomy.

Here’s to our amazing staff who make it all possible! 🎉

Let’s go, airglow! 🧡
An orange glow hangs over Gemini North on Maunakea in Hawaiʻi. It’s airglow — light from atoms in Earth’s upper atmosphere. Orion and Sirius shine beyond.

What’s it like to drive up Cerro Pachón in Chile after the July storm? 🚙❄️
There’s still a little snow on the mountain, making for some spectacular views along the way.

This footage was taken in September 2026.

Clean, pristine spiral galaxies are fine, but we also like messy cosmic collisions.💥🌌
Centaurus A, seen here, is the byproduct of a merger between an elliptical galaxy and a smaller spiral galaxy.

A “typical” night shift at Cerro Pachón (if your definition of typical includes this view 🌌)

Watch the sky above the SOAR Telescope in Chile. SOAR is among the best research facilities available to astronomers in the Southern Hemisphere

Black holes: the Universe’s ultimate introverts. 🕳️
They pull you in, but they never open up. 👀

Happy September equinox! 🌞

Today marks one of two occurrences during the year where night and day last nearly an equal 12 hours. It also kicks off autumn in the Northern Hemisphere and spring in the Southern Hemisphere. 🍃🌎🍂

Somewhere between “I’ll just take a quick look” and “wait… WHAT am I looking at?”🤯 lies this cosmic treasure chest.

The large galaxy at the top is NGC 4261. Down in the bottom-left is NGC 4281, a lenticular galaxy.

High atop Cerro Pachón in Chile, the 4.1-meter SOAR Telescope gives astronomers a powerful view of the southern sky. Built for speed and precision, SOAR explores the cosmos from optical to near-infrared light.
Can you tell us what SOAR stands for? 🤔
