Five 'mass extinctions' have decimated our planet since it was formed - now scientists claim the answers to two could be written in the stars.

Astronomers have discovered four planets that are just a fraction of the mass of Earth orbiting Barnard’s Star, which is 6 ...

The planets closely orbit Barnard’s Star, zipping around their stellar host in a matter of days, compared with the year it takes Earth to complete one orbit around the sun. The outermost planet ...
