A nearby planet has been torn apart by a white dwarf at the center of the Helix Nebula, helping to solve the mystery of strange X-ray signals from the nebula.
The X-rays likely come from the remains of a planet that got too close and was destroyed by the white dwarf's powerful gravity.
Observations suggest that leftover debris from the destroyed planet is still orbiting the white dwarf.
This discovery provides insights into the fate of planets when their stars transform into white dwarfs.
