☄️ Say hello to Comet 3I/ATLAS as seen by NSF–DOE Rubin Observatory! Comet 3I/ATLAS is just the third interstellar object ever spotted in our Solar System. Rubin Observatory didn’t discover it, but… Interstellar Object Comet 3I/ATLAS as seen by NSF–DOE Rubin Observatory!

☄️ Say hello to Comet 3I/ATLAS, just the third interstellar object ever seen in our Solar System!

NSF–DOE Rubin Observatory didn’t discover the comet, but even during testing, it caught a glimpse. Imagine what we'll find once full science operations begin later this year! 🔭🧪

Interstellar Comet 3I/ATLAS: What We Know Now Observations have revealed the comet’s fuzzy coma, hinted at a weird tail, and suggested an ancient history.

Black and white photo of Sau Lan Wu standing in front of a chalkboard. She is wearing a floral jacker, and is holding her right hand up at roughly shoulder height with her index finger touched to her thumb. She has long black hair, is smiling, and is looking at the camera.

Physicist Sau Lan Wu was born #OTD in 1940.

She co-discovered three jet events in the TASSO experiment at DESY (supporting the existence of gluons), was on the team that discovered the J/Ψ particle, and works on the ATLAS experiment at CERN. 🧪 ⚛️ 👩‍🔬
