A metal scar found on the dead star's surface had never been seen before, said astronomer John Landstreet.
It was discovered at the astronomical research centre in Armagh Observatory and Planetarium.
The scar, believed to be 500km (310 miles) long, was on an Earth-sized remnant of a star from a nearby solar system.
The system no longer creates energy at its core, so the star is dead.
