This week's science story: Discovery of an Earth-sized planet orbiting a cool, calm star about 11 light years away
Space scientists have confirmed the discovery of an Earth-sized planet orbiting a cool, calm star about 11 light years away.
As names go, Ross-128b belies the exciting potential of this remote, Earth-sized planet to harbour life. Perched in orbit around the dimly-glowing Class M red dwarf star called Ross 128, which is about one fifth of the size of the Sun, Ross 128b has taken researchers at the European Southern Observatory (ESO) more than a decade to detect.
The Naked Scientists says it has taken scientists; Xavier Bonfils and his colleagues about a decade to confirm the existence of this planet.
He goes on to say the planet has very good prospects of being Earth-like and possibly where life could be started.
