Story summary
- A study in Astronomy & Astrophysics links a supernova 10 million years ago to Earth, using beryllium-10 from the Pacific Ocean.
- Researchers tie the beryllium-10 to cosmic rays from the nearby supernova.
- They estimate the event occurred 35–100 parsecs (114–326 light-years) from Earth, possibly in the Orion region.
- The findings suggest understanding ancient supernovae is vital for long-term life and environmental impacts and guiding future life-search efforts.
