Introducing...your sneak peek at the cosmos captured by NSF–DOE Vera C. Rubin Observatory!

Can you guess these regions of sky?

This is just a small peek...join us at 11am US EDT for your full First Look at how Rubin will #CaptureTheCosmos! 🔭🧪

#RubinFirstLook

A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. The image focuses on a collection of interacting galaxies connected by delicate streams of stars. At top center lies a large elliptical galaxy that is dense and smooth, like a polished stone glowing with golden light. Like delicate spider silk or stretched taffy, these stellar bridges link the large elliptical to the few larger galaxies beneath, evidence of past collisions. All throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors against the black of space. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black. A cosmic tapestry of glowing tan and pink gas clouds with dark dust lanes. In the upper right, the Trifid Nebula resembles a small flower in space. Its soft, pinkish gas petals are surrounded by blue gas, and streaked with dark, finger-like veins of dust that divide it into three parts. It radiates a gentle, misty glow, diffuse and soft like the warmth of breath on a cold hand. To the lower left, the much larger Lagoon Nebula stretches wide like a churning sea of magenta gas, with bright blue, knotted clumps sprinkled throughout where new stars are born. Both nebulae are embedded in a soft tan backdrop of gas that is brighter on the left than on the right, etched with dark tendrils of dust and sprinkled with the pinpricks of millions of stars. A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. To the lower left is a region filled with the hundreds of golden glittering gems of a distant galaxy cluster. In the foreground, below and right of center, two blue spiral galaxies look like eyes beneath the entangled mass of a triple galaxy merger in the upper right. A few bright blue points of foreground stars pierce the glittering tapestry.

A quarter for your thoughts? 🪙

We think Vera C. Rubin is a great choice to be honored with a quarter... and with an observatory! Rubin was an accomplished astronomer who provided the first convincing evidence of dark matter, influencing a new subfield of astrophysics. 🧪🔭

In the bottom third, text reads "U.S. Mint American Women Quarters Program. Dr. Vera Rubin is now on a U.S. quarter!" To the right of the text is an image of the Vera Rubin quarter.

This gives the telescope ENORMOUS light-collecting power while being compact! 🔆

The primary mirror is 8.4 m in diameter – taller than the height of a two-story house. Yet, the telescope also has a compact design so it's fast enough to cover the entire visible sky in just a few nights.

🔭 🧪
Rubin Observatory and its companion 1.2-meter telescope atop Cerro Pachón. Rubin is a boot-shaped building on the left with long white service sticking toward us and angular silver dome sticking up. The vertical dome slit is open, revealing the shiny ring of the top end of the 8.4-meter telescope. On the right, the small dome of the companion telescope sits atop its own hill.

We're worth the hype 😎 The 8.4-meter Simonyi Survey Telescope is part of what makes NSF–DOE Rubin Observatory so unique. Why?

Its primary mirror is the first of its kind, with two differently curved optical surfaces to direct light into the car-sized LSST Camera.

Eye to the sky…on-sky engineering tests have begun at NSF–DOE Rubin Observatory using the world’s largest digital camera! 🔭🧪

After installing and testing the LSST Camera, we turned the telescope to the sky—a moment 20 years in the making!

With that, Rubin #CommissioningNotes are back ✍️

🧵
Around two dozen people sit and stand at a long desk with computer monitors out of view. Several people are smiling or have their mouths open in amazement. One person in the back has their arms raised in celebration.

Now that the world's largest digital camera is installed, what work remains before Rubin goes live?

For starters, hooking up and testing all the camera's connections to the telescope, before cooling it down to -100 C (-148 F) 🥶

The huge LSST Camera mounted in the center of Rubin's Observatory's telescope. The camera is seen end-on, and look like a long black cylinder ending at a mirror. To the left and right of the camera, scaffolding is set up to allow work access to the camera.

Lights, camera, action!

The world's largest digital camera has been installed at NSF–DOE Rubin Observatory! 🤩

The LSST Camera was the final major component of the observatory. With it in place, Rubin officially enters its final phase of testing!🔭

You spin us right round, right round 🎶

Our summit team recently tested the function that the camera rotator is named for and all went well!

The remaining steps to complete before we install the largest camera in the world on our telescope are rapidly shrinking...stay tuned! 👀

When you turn it on and it works spectacularly!

The Rubin team has successfully completed the first on-sky engineering tests using the 144-Mpx engineering camera. Up next: installing the largest digital camera in the world, LSST Camera! 🔭🧪
