Like many science journalists this week, I'll covering the #ArtemisII mission for @nature.com. Our first story is now up! We explore the science that the astronauts will do on their flight — and how this advances beyond the Apollo era. 🧪🔭 www.nature.com/articles/d41...

☄️ 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! 🔭🧪
