The discovery of a distant, Earth-like planet offers a stark warning; our own planet could face a similarly barren future once the sun exhausts its life cycle.
Studying the newly discovered planet reveals it was once habitable, orbiting a sun-like star, but now exists outside the white dwarf's habitable zone.
As our sun approaches the end of its life, it will not only vaporize Earth's oceans, but also potentially increase Earth's orbital distance significantly.
Once the sun becomes a red giant, it will expand dramatically, potentially incinerating inner planets like Mercury and Venus while drastically affecting Earth.
