Your vote counts! Help us bring Rubin Observatory to @SXSW 2025. Vote TODAY for our panel: "Revealing the universe's secrets with the biggest movie ever made." bit.ly/3LVAXvg #SXSW2025

Rubin Observatory doesn't look like other observatories, & its telescope doesn't move like others—it's way faster! But why? To answer cosmic questions we haven't been able to answer, we had to build an observatory unlike any other. Learn more via U.S. National Science Foundation ➡️ new.nsf.gov/science-matter…

The U.S. National Science Foundation-DOE Rubin Observatory will revolutionize the understanding of the cosmos. By capturing a high-precision chronicle of the universe, new insights into dark matter and dark energy will be uncovered.

Reminder! You still have five days to cast your vote for sessions for #SXSW2025! Might we suggest a vote for the U.S. National Science Foundation - DOE Office of Science Rubin panel? 🤩 Voting is open until August 18! 🔗: ls.st/sxsw2025

Say cheese! Rubin Observatory photographs pretty well, in our (not so) humble opinion ✨ Celebrate #WorldPhotographyDay with us by grabbing one of these new wallpapers for your phone! 📱📷

Everything we can see - or even measure with instruments - makes up only 5% of the universe. The rest is a mystery. Using a camera built SLAC to take massive images of the night sky, the U.S. National Science Foundation-DOE Rubin Observatory will vastly expand our knowledge: new.nsf.gov/science-matter…

📹 SLAC's Sydney Erickson is working to better understand dark energy, an unknown form of energy that causes the universe to expand at an accelerating rate. Rubin Observatory Read more: stanford.io/3CTulcw #SLACExplains #capturethecosmos #Astronomy #DarkMatter #DarkEnergy

Commissioning camera: ✅ With ComCam reinstalled, we officially have 2 out 3 main telescope components in place! In just a few weeks, summit staff will install the 8.4-meter primary/tertiary mirror—and Rubin will finally have a complete telescope system for the very first time!
