The planet was discovered in the “habitable zone” of the star, where it is neither too cold nor too hot for life to exist. The research was published in the Royal Astronomical Society’s monthly notices. The observation was absolutely unique to astronomers, according to Prof. Jay Farihi of University College London, who led the study. “This is the first time that anything has been seen in the habitable zone of a white dwarf. And thus there is a possibility of life on another world orbiting it,” he told in an interview. When huge stars die, they become black holes, but smaller stars, such as our Sun, become white dwarfs, or stars that have burned up all of their nuclear fuel and lost their outer layers. When they first form, they are the size of a planet and radiate a bluish-white light. The hypothetical planet is 60 times closer to the star than our planet is to the Sun, and it is 117 light-years away from Earth.
The researchers don’t have clear proof of the planet’s existence, but the movement of 65 Moon-sized objects around the white dwarf’s habitable zone suggests it exists. The distance between the structures does not fluctuate, indicating that they are affected by the gravity of a nearby planet. “Usually in astronomy, if we find one, it usually means that it’s common,” said Prof. Farihi.
