Eight billion years into the future, astronomers have discovered what may be a future Earth.
Astronomers have got a unique look at what our planet might look like in eight billion years.
The planet, known as KMT-2020-BLG-0414, is a rocky world 4,000 lightyears away from Earth that orbits a white dwarf, which is the burning remnant of a star.
In 5 billion years, our sun is predicted to change into a white dwarf.
But before then, Mercury, Venus, and maybe even Earth and Mars will be consumed by our sun as it accelerates outward into a red giant.
Humans may migrate to the icy moons Europa and Enceladus, which will become water worlds as the sun becomes a red giant.
