A strange X-ray signal is the dying scream of a planet destroyed by a superdense stellar corpse called a white dwarf.

The signal originates from the heart of the Helix Nebula , which is the remains of a star similar to the sun.

White dwarfs like WD 2226-210 don't normally give off strong X-rays.

Astronomers had already suspected a Neptune -sized planet orbits the destructive dead star so closely that its year lasts three Earth days .
