       |  _The radiation was a tell-tale sign of iron atoms that had been
       | so battered that they lost nine electrons -- the so-called "Fe X"
       | (or "Iron 10") line. The researchers checked another candidate
       | and found the same trait. While neither object had the
       | traditional appearance of a feeding black hole, it was hard to
       | imagine what else could be doing such violence to iron atoms._
