Massive Superflare Eruption Observed from Distant Star

Astronomers have observed a superflare on one of the stars in the V1355 Orionis binary system, which is ten times more extensive than the largest solar flare ever recorded on the Sun. The superflare began with a massive, high-velocity prominence and developed into a coronal mass ejection that carried trillions of tons of material away into space. Understanding flares on stars, and why they occur, is important as they could affect the evolution of any nearby planets and their atmospheres.
