NATAL, Brazil, May 20 (UPI) -- A distant star that's a twin to the sun but 2 billion years older may foretell Earth star's future and that of the planet, a team of Brazilian astronomers says.
If the sun evolves like its newly discovered relative, dubbed CoRoT Sol 1 -- the farthest of the so-called solar twins in the Milky Way galaxy -- all the water on Earth will boil away, they said.
