Jakarta – astronomers may have cracked the puzzle of mysterious X-ray signals emanating from a dying star, a phenomenon that has baffled scientists since the 1980s.New data from NASA’s Chandra X-ray Observatory and the European Space Agency’s XMM-Newton satellite suggest a planet may have been consumed by a white dwarf, one of the faintest stars in the universe, located at the heart of the planetary nebula known as the Helix Nebula, or “WD 2226-210.”
The Helix Nebula and its Central White Dwarf
Planetary nebulae represent the final stage of a star’s life, characterized by the expulsion of its outer layers, leaving behind a small, dim star known as a white dwarf at its center.
We may have finally found the cause of a mystery that has lasted for more than 40 years.

A Planetary Death Knell?
The observed X-ray signals could be the result of planetary debris being drawn into the white dwarf.
We think these X-ray signals could be from the debris of a planet being pulled into the white dwarf, as a death knell from a planet being destroyed by the white dwarf in the Helix Nebula.
If confirmed, this would be the first instance of a planet observed being destroyed by a central star within a planetary nebula.
Chandra X-ray Observatory Data Reveals clues
The Chandra X-ray Observatory data provides compelling evidence.
The latest data suggests ther may be a subtle and regular change in that X-ray signal every 2.9 hours, giving evidence of remnants of a planet extremely close to the white dwarf.

Orbital Dynamics and Planetary Migration
Scientists previously suggested a neptune-sized planet orbited the white dwarf closely, completing a revolution in under three days. Though, recent studies propose a Jupiter-like planet could be even closer.
The CXC explains the potential orbital dynamics:
the planet could have originally been at a considerable distance from the white dwarf,but then migrated inward because of interactions with the gravity of other planets in the system. Once it got close to the white dwarf, the star’s gravity would have torn apart some or all of the planet.
Implications for Understanding Stellar Evolution
Understanding these systems is crucial for comprehending the life cycle of stars like our Sun and the fate of their planetary companions.
It’s important to find more systems like this because it can teach us about the survival or destruction of planets around stars like the Sun as they enter old age.

Key Findings:
- mysterious X-ray signals from a dying star may be caused by a planet being destroyed by a white dwarf.
- Data from the Chandra X-ray observatory supports this hypothesis.
- The discovery could provide insights into the fate of planets orbiting aging stars.
