Superflare with massive, high-velocity prominence eruption

A team of astronomers detected a massive superflare and prominence eruption on the star V1355 Orionis, which was capable of breaking free from the star's gravity and developing into Coronal Mass Ejections. The event released trillions of tons of material, making it one of the most massive ever observed.
