Iron bar found in Ring Nebula may reveal Earth’s future fate

Scientists have detected a never-before-seen 'iron bar' slicing through the Ring Nebula, 2,283 light-years away. Made of ionised iron, the structure has stunned astronomers and may be the remains of a vaporised Earth-like planet. Researchers say it could offer a chilling preview of what awaits Earth when the Sun turns into a red giant.
