Hoping to find out whether the Sun is capable of producing superflares, which are thousands of times more powerful than a solar flare, a team of scientists pored over data of 56,000 Sun-like stars.

The star was likely much larger than our sun. Studying an event like this can reveal more details about the collapse of stars, how matter interacts near the speed of light, and what conditions may ...
