In six billion years, the sun will expand into a red giant, potentially consuming Mercury and Venus, and possibly incinerating Earth. However, scientists have discovered a rocky planet orbiting a white dwarf, suggesting Earth might survive by moving to a more distant orbit. This planet, found 4,000 light-years away, once orbited its star at a similar distance to Earth’s current orbit before being pushed outward. The discovery, made using microlensing, offers hope that Earth could endure the sun’s red giant phase. Further observations await more powerful telescopes.
