The Helix Nebula, also known as NGC7293, is a planetary nebula located 650 light years away in the constellation Aquarius.
X-ray emissions from the Helix Nebula have been identified as coming from the white dwarf at its center, designated WD 2226-210.
The emissions may be the result of a planet destroyed by the central star, as researchers propose the possibility of a destroyed Jupiter-like planet.
Observations reveal a consistent brightness and a periodicity of 2.9 hours in the X-ray signal, suggesting the presence of planetary remnants in close orbit around the white dwarf.
