Space Science Saturday!
Scientists may have found the source of the most powerful neutrino ever detected!

According to Science Daily {https://www.sciencedaily.com/releases/2026/05/260523103912.htm} , a new study from the journal of cosmology and Astro particle physics shows that a mysterious particle from deep space has an interesting origin. Scientists were buzzing in 2023 after the most energetic neutrino ever detected slammed through the Mediterranean Sea. Now, researchers think they may have identified the cosmic “culprits” behind it: blazars; supermassive black holes blasting jets of matter straight toward Earth!
