Their existence points to the likelihood that Earth-sized worlds have been forming throughout most of the time that the universe has been around and should therefore be extremely common.The planets were found thanks to data collected by the Kepler Space Telescope which has so far identified 1,103 worlds orbiting distant stars and over 4,000 additional planetary candidates.

"There are far-reaching implications for this discovery," said Tiago Campante of the University of Birmingham. "We now know that earth-sized planets have formed throughout most of the Universe's 13.8 billion-year history, which could provide scope of the existence of ancient life."
