#RubinObservatory
To celebrate the approaching end of NSF–DOE Rubin Observatory's construction period, we're reminiscing through the eyes of some of our talented staff.

Join us for the #RubinConstructionArchives series, every Tuesday and Thursday on Youtube through November! 🔭 🧪

8 new Near-Earth Asteroids have been discovered by the Vera Rubin Observatory from just 10 hours of sky scanning over the course of a few nights. Imagine what Rubin will do when it's fully operational. #LSST #RubinObservatory #NEO

Those 4 interacting galaxies is amazing. I can't stop staring at the whole image: skyviewer.app/explorer

Rubin's Cosmic Treasure Chest is an appropriate name.

Welcome to Rubin's #CommissioningNotes! Entry 1️⃣: we're in full swing!

Ok, but what's "commissioning?"

Rubin Observatory is the result of millions of hours of work by thousands of people around the world -- and now all that work is coming together! 🔭🧪

Like your digital camera, but bigger.

Much bigger.

The LSST Camera looks remarkably like a super-sized handheld digital camera. Here's how it stacks up against the camera you might have at home!

Which surprised you the most? 🔭🧪

Gave my talk on #RubinObservatory today at my local #u3a - Going to be the “gift that keeps on giving” assuming #megaconstellations let it do its job! Such an impressive set-up over in Chile 👏👏👏 #astronomy

If you want to see the 8 new #NEA asteroids discovered by the Vera C. Rubin Observatory tonight, northern hemisphere observers need to look to the southwestern sky. Not surprising, because #RubinObservatory is in Chile. They're also mag 24-25 so you'll need a huge telescope too.

The Vera C. Rubin Observatory in Chile is poised to scan the sky nightly for 10 years. And we get our first look at the images from the #RubinObservatory at 10 a.m. CDT tomorrow!

Watch the first look in the player here!

“First Light”

One year after Rubin First Look, the invitation still stands:

Come, all you watchers—young and wondering—

the sky has something new to show.

Not what we were, but what is waiting

just beyond what we can know.

The Rubin Observatory identified the fastest-spinning asteroid larger than 500 meters ever found. This record-breaking object was spotted during pre-survey commissioning, proving the new facility can detect what others miss.
