Excited astronomers say that the discovery of a solar system with strong similarities to our own raises the chances of other life out there. The system has two gas giants similar to Jupiter and Saturn orbiting at a similar distance from the alien sun 5,000 light years away, and rocky, Earth-like planets may exist in closer orbits, reseachers write in the journal Science.
Experts believe the existence of this system could mean there are many similar solar systems to our own out there, and the more Earth-like planets there are, the likelier extra-terrestrial life is, the Daily Telegraph reports. "Once we know that planets similar to Earth are common, it is straightforward to investigate whether these harbor any forms of life," a professor said. (More space stories.)
