Astronomers discovered an Earth-like planet 4,000 light years away, offering a glimpse into Earth’s potential future when the sun becomes a white dwarf. This system, observed with the Keck telescope, features a white dwarf and an Earth-sized planet in a distant orbit. As the sun evolves into a red giant, it will likely force Earth to migrate outward, possibly doubling its current orbit. This process, starting in about 1 billion years, will vaporize Earth’s oceans. The discovery, to be published in Nature Astronomy, helps scientists understand stellar evolution and its impact on planetary systems.
