Shock proof: The Earth is in danger of being ripped apart by an unsuspecting enemy
According to Science Alert, a research team represented by astrophysicist Benjamin Zuckerman from the University of California at Los Angeles (UCLA - USA) presented at the 240th meeting of the American Astronomical Society on the amazing findings. from G238-44, a white dwarf.

White dwarfs are originally "zombies" of Sun-like stars, with huge masses but compressed into a small Earth-sized object. Stars that run out of energy will eventually explode into red giants, then collapse into white dwarfs. Our sun will be like that in less than 5 billion years.
Like other white dwarfs, G238-44 is not dead yet. Researchers have found shocking evidence that this dead parent star is tearing apart and eating the planets it once created and nurtured while "alive".
It is also so greedy that it "eats" things from the cold outer edges of the old star system, similar to the icy Kupier Belt material outside the solar system. This is revealed by the recent accretion of metallic and dead star rock.
10 elements heavier than helium have been discovered: carbon, nitrogen, oxygen, magnesium, aluminum, silicon, phosphorus, sulfur, calcium and iron, pointing directly to planets, asteroids and other elements. another object in the white dwarf's meal.
This is the first time that a white dwarf accretion of both the interior and exterior of the star system has been identified.
And it's a macabre "window of time" for humanity. If we are lucky enough to escape the danger that the Sun may become too large during the red giant phase, swallowing Mercury, Venus, Earth, Mars; we could still be ripped apart by it in the white dwarf stage.
