Mysterious 'Ring Nebula' Reveals Iron Bar, Hints at Destroyed Planet

• The Ring Nebula, Messier 57, a well-known object 2,600 light-years away, continues to hold scientific mysteries despite centuries of observation.
• New research using the WEAVE instrument on the William Herschel Telescope discovered a 3.7 trillion-mile-long bar-shaped cloud of iron atoms within the nebula.
• This iron feature is unusual as no other elements in the nebula share the same shape, leading to speculation it could be from a destroyed rocky planet.
• The amount of iron detected is comparable to Earth's molten iron core, though this theory remains unproven.
• Led by Roger Wesson of Cardiff University, the study highlights new discoveries in a familiar cosmic object, aiding understanding of stellar evolution and element distribution.
