We Should Be Able To Hear 'Ghost Waves' Emitting From Dead Planets

  • 5 years ago
Dead planets orbiting dead stars can give off ghostly radio wave emissions that are detectable from Earth.
They allow us to track planets even billions of years after their stars have run out of fuel.
Researchers believe we could “tune into” radio waves given off by the cores of exoplanets that orbit around white dwarfs.
A core is created when a planet orbits a star which has burned through its fuel and stripes away its outer layers.
