For decades, astronomers have seen the "before" and "after" of this process — when a planet is orbiting very close to its star and the bloated stellar old-timer has engulfed the planet. Just last year, an MIT-led research team caught a dying star in the act of absorbing a planet.

The discovery of an Earth-like planet 4,000 light years away in the Milky Way galaxy provides a preview of one possible fate for our planet billions of years in the future, when the sun has turned into a white dwarf,

A distant star system offers hope that our planet will keep spinning, even after the Sun expands into a red giant.

While the poet Robert Frost wrote that “Some say the world will end in fire/ Some say in ice,” earthlings may take cold comfort from a newly published discovery that suggests the latter is more likely than previously believed.
