Heads up, science squad! 🚀 On August 26, 2025, the Jiangmen Underground Neutrino Observatory (JUNO) hit a milestone: filling its giant tank with 20,000 tonnes of liquid scintillator and officially kicking off data collection. Located 700 meters under Guangdong in the Chinese mainland, JUNO is now the world's first ultra-large, ultra-precision neutrino experiment.
So, what’s the big deal? Here’s why it matters:
- Neutrino Mass Ordering 🔬: Scientists will tackle one of particle physics' biggest puzzles—figuring out the exact mass hierarchy of neutrinos, tiny particles that barely interact with matter.
- Solar, Supernova & Earth Neutrinos 🌞⭐🌍: JUNO can catch neutrinos from the sun, exploding stars, Earth’s core, and the atmosphere, opening a new window into our universe.
- Beyond Design ⚙️: Early data shows JUNO’s sensors outperform expectations, giving researchers extra power to hunt signals!
For young science buffs across South and Southeast Asia, this is your backstage pass to cutting-edge astro-research. Stay tuned as JUNO peels back cosmic layers and brings us closer to the secrets of the universe ✨.
