Can you guess what this is?
Hint: it’s a piece that will soon belong to a 7000-tonne detector #AtCERN. 😉

Here we see the first ring of the @atlasexperiment Inner Tracker (ITk) Pixel Inner System, loaded with detector modules by teams at @slac_lab in early October.

ITk is a next-generation tracker that will transform the way the ATLAS experiment detects particle collisions for the #HiLumiLHC.

The ring will be located closer to the beam pipe than any other part of ATLAS, right at the heart of the detector, where protons collide in the #LHC.

The modules on the first side are now in place, and initial measurements confirm they are correctly positioned, providing an encouraging start to this stage of assembly.

Look what just flew into view! 🪶✨

Meet the Seagull Nebula as seen by NSF–DOE Rubin Observatory's engineering test camera, ComCam. Two years ago this month, ComCam began on-sky testing — the first time Rubin opened its eye to the sky!

Those glowing pink clouds? That's hydrogen gas energized by intense radiation from newborn stars. The blue haze shows cosmic dust scattering starlight, while the seagull’s piercing “eye” is a massive young triple-star system known as HD 53367.

At 144 megapixels, ComCam was Rubin’s warm-up act before the giant 3200-megapixel LSST Camera took the stage. This image release today commemorates that first 7-week on-sky period two years ago, which paved the way for #RubinFirstLook and the start of full science operations.

Not bad for a first observing run, right? 🔭

¡Mira quién acaba de aparecer en escena! 🪶✨

Conoce la Nebulosa de la Gaviota, captada por la ComCam, la cámara de pruebas de ingeniería del Observatorio Rubin de NSF–DOE. Hace dos años, en este mismo mes, la ComCam comenzó sus pruebas de observación del cielo: ¡fue la primera vez que Rubin abrió su ojo al Universo!

Las nubes rosadas que brillan en la imagen son gas de hidrógeno energizado por la intensa radiación de estrellas recién nacidas. La neblina azul corresponde a polvo cósmico que dispersa la luz de las estrellas, mientras que el penetrante "ojo" de la gaviota es un sistema masivo de tres estrellas jóvenes conocido como HD 53367.

Con 144 megapíxeles, la ComCam fue el ensayo previo a la gran protagonista: la Cámara LSST de 3.200 megapíxeles. La publicación de esta imagen conmemora aquellas primeras siete semanas de observaciones en el cielo, hace dos años, que allanaron el camino para la #PrimeraLuzdeRubin y el inicio de las operaciones científicas a plena capacidad.

Nada mal para una primera ronda de observaciones, ¿no? 🔭

#RubinObservatory #astronomy #astrophysics #nebula #SeagullNebula A close-up view of billowing cosmic gas clouds in soft peach-pink and powdery sky-blue. Near the upper center, warm pink gas meets cool blue mist, sliced by a jagged, snaking column of dark dust like a tear in the cloud. The lower half settles into textured, dusky blue and charcoal dust. Several bright, ice-blue stars surrounded by soft halos and a dusting of fine pinpoint stars sparkle across the velvety, glowing mist.

⚡ Una cámara capaz de congelar un electrón: récord mundial de pulso de rayos X, 100 a 400 attosegundos.

Científicos del láser LCLS de SLAC midieron los pulsos de rayos X de alta energía más cortos jamás registrados. Un attosegundo es una milmillonésima de una milmillonésima de segundo. Sirven para ver electrones moverse dentro de átomos y plasmas.

⚡ A camera that can freeze an electron: a world record for the shortest high-energy X-ray pulses, 100 to 400 attoseconds.

Researchers at SLAC's LCLS laser measured the shortest hard X-ray pulses ever recorded at an X-ray free-electron laser, letting scientists watch electrons move inside atoms and plasmas.

🧬🔬 E se pudéssemos assistir à formação da penicilina, átomo por átomo?

Parece ficção científica, mas é ciência!

Em um estudo publicado em 9 de outubro de 2026, na revista Nature Catalysis, pesquisadores utilizaram pulsos ultrarrápidos de raios X para investigar uma reação fundamental na biossíntese da penicilina.

🧪 A protagonista é a enzima isopenicilina N sintase (IPNS), que, com a participação de ferro e oxigênio, catalisa a formação dos dois anéis característicos do núcleo das penicilinas: o β-lactâmico e o tiazolidínico.

⚛️ O mais fascinante? Os cientistas reconstruíram diferentes etapas da reação em resolução atômica e descobriram que moléculas de água e regiões da enzima distantes do centro ativo desempenham papéis importantes na catálise.

🎬 Inspirado nessa descoberta, recriei em animação molecular 3D no Blender uma representação da transformação química, aproximando a pesquisa científica da divulgação da ciência.

💡 Compreender como a natureza constrói moléculas tão importantes pode abrir caminhos para o desenvolvimento de novos antibióticos.

Welcome to Chile, @slac_lab LSST Camera team colleagues!

They arrived from California last week for scheduled camera work during NSF–DOE Rubin Observatory’s planned engineering downtime. This engineering period will last about three weeks in total. During this time, teams will carry out maintenance and other work, including maintenance work on the LSST Camera from the SLAC team.

Planned engineering downtimes are common in ground-based astronomy, especially in winter when the weather tends to be less favorable. This is a good time to do the important maintenance that keeps the observatory running smoothly during the rest of the year! 🔧🔭

¡Bienvenidos a Chile, equipo de la Cámara LSST del SLAC!

Han llegado la semana pasada desde California para realizar los trabajos programados en la cámara durante la parada técnica programada del Observatorio Rubin de NSF–DOE, que se extenderá por unas tres semanas en total. Mientras el observatorio está en pausa, los equipos aprovechan este tiempo para realizar mantenimiento y otras tareas esenciales. Entre ellas, el equipo del SLAC llevará a cabo trabajos de mantenimiento de la Cámara LSST.

Las paradas técnicas son parte habitual de la operación de los observatorios terrestres, especialmente en invierno, cuando las condiciones meteorológicas suelen ser menos favorables. Es un buen momento para realizar el mantenimiento necesario y asegurar el buen funcionamiento del observatorio durante el resto del año. 🔧🔭

MPL Summer 2026 at @slac_lab! 😎

SF State student researchers (Sam, Zeke, and Milo) spend the summer studying tendon nanostructure using small-angle X-ray scattering (SAXS) at the SLAC National Lab at Stanford with collaborators from NASA and SFSU Chemistry (Dr. Ichimura).

This machine is basically a giant round factory that produces the brightest X-ray light on earth to shine through our samples. This allows us to see the organization of collagen fibers at the nano-scale. Our collaboration requires expertise from chemistry, engineering, and kinesiology/physiology. Look for data coming soon!!

Just a totally normal, run-of-the-mill camera 📷

If your definition of “normal” includes:
🚗 The size of a car
🔭 A 3.2-billion-pixel sensor
🌌 A field of view that could fit ~45 full Moons
❄️ An operating temperature of −100°C
⏱️ A new 8-gigabyte image every ~40 seconds

Okay, maybe that's not normal.

NSF–DOE Rubin Observatory's LSST Camera is the largest digital camera ever built (thanks @slac_lab!). Over the next ten years, together with Rubin's 8.4-meter telescope, it'll #CaptureTheCosmos repeatedly every few nights and build the most complete timelapse record of the Universe we've ever had. #OnThisDay in 2020, we released its first-ever 3200-megapixel image, taken of a Romanesco! #OTD

Totally normal stuff.

Es una cámara totalmente normal, de lo más común 📷

Bueno, si tu definición de “normal” incluye:
🚗 El tamaño de un auto
🔭 Un sensor de 3.200 millones de píxeles
🌌 Un campo de visión capaz de abarcar unas 45 Lunas llenas
❄️ Una temperatura de operación de −100 °C
⏱️ Una nueva imagen de 8 gigabytes cada ~40 segundos

Entonces… quizás no sea taaan normal 😏

La Cámara LSST del Observatorio Rubin de NSF–DOE es la cámara digital más grande jamás construida (¡gracias, @slac_lab!). Durante los próximos diez años, junto con el telescopio de 8,4 metros de Rubin, va a #CapturarElCosmos una y otra vez en unas pocas noches para construir el registro en cámara rápida más completo que jamás hayamos tenido del Universo. El #EnUnDíaComoHoy de 2020, publicamos nuestra primera imagen de 3200 megapíxeles, ¡capturada de un romanesco! #TalDíaComoHoy

Todo muy normal. Cosas de todos los días.
