Story summary

The study suggests coronal mass ejections from the young star EK Draconis shaped atmospheres of Earth, Mars, and Venus, aiding life’s origins.
An international team led by Kosuke Namekata of Kyoto University observed these CMEs.
They observed a CME with hot plasma at 300–550 km/s, followed by cooler gas at 70 km/s.
The findings were published in Nature Astronomy and highlight CMEs' role in shaping planetary environments and life conditions.
