A coronal mass ejection on another star has been witnessed in its entirety for the first time, revealing that when these violent outbursts take place on young stars, they pack enough energy to potentially kickstart the chemistry of life on any orbiting planets.

Young stars can be much more tumultuous than older stars. Stellar physics predicts that in our sun's formative years it was throwing off flares of radiation and coronal mass ejections (CMEs) far more powerful and more frequent than what the sun can manage today.

Yet no one had actually seen a young sun-like star being so energetic — until now.

A coronal mass ejection and its accompanying flare occur when taut magnetic field lines on the sun or another star snap, releasing a huge burst of energy before the field lines reconnect. T
