Helix nebula

Central star 
One study says that the white dwarf within the Helix Nebula destroyed a Jupiter-sized planet, creating a strange X-ray signal. Another study from 2025 found from X-ray observation that the central star may be accreting the remains of that planet. This would be closer than the planet found via optical variability.
