Astronomers have discovered a distant planet that has offered them a rare glimpse of what our planet may look like 8 billion years in the future.
The planet, called KMT-2020-BLG-0414 and located 4,000 light-years from Earth, is a rocky world orbiting a white dwarf — the embering husk of a star. Our sun is expected to transform into a white dwarf in 5 billion years’ time.
