☄️ 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! 🔭🧪
Some great coverage by David L. Chandler at Sky & Telescope about our recent MNRAS paper on 3I/ATLAS:
