[00:00:00]In the silent void between stars, a rogue planet drifts alone, a cold world without a sun to warm it.

[00:00:06]Its surface hides ancient scars from unfettered gravity, while faint internal heat keeps oceans and rocks from freezing solid.

[00:00:14]Astronomers detect these wanderers by their slight gravitational tug on nearby stars and by the faint glow from [music] lingering heat.

[00:00:22]If such a planet harbored life, it would rely on geothermal energy and occasional meteoric heat to power a fragile biosphere.
