Summary:
- Astronomers have detected an X-ray signal that may indicate the remains of a destroyed planet orbiting a dead star, or white dwarf, called G29-38.
- The X-ray signal suggests the presence of heavy elements like iron and nickel, which are typically found in the cores of planets.
- This discovery provides insights into the fate of planetary systems after their host stars die and could help understand the composition and structure of exoplanets.
