Story summary

The young Sun-like star EK Draconis produced a two-component coronal mass ejection, with hot plasma at 100,000 Kelvin moving 300–550 km/s, followed by cooler gas at 10,000 Kelvin moving 70 km/s.
Researchers used the Hubble Space Telescope and ground-based telescopes to detect the ejection components.
The study indicates strong CMEs could have influenced early planetary atmospheres and potentially the emergence of life on Earth and other planets.
